In lunar religious calendars, Ashvin begins on the new moon or the full moon around the time of the September equinox . Ashvini is the first star that appears in

230-642: A leap day being added to February in the leap years . The months and length of months in the Gregorian calendar are the same as for the Julian calendar. The only difference is that the Gregorian reform omitted a leap day in three centurial years every 400 years and left the leap day unchanged. A leap year normally occurs every four years: the leap day, historically, was inserted by doubling 24 February – there were indeed two days dated 24 February . However, for many years it has been customary to put

345-562: A two-volume printed version of the Vulgata in the early 1450s. High and Low German , Italian, Dutch, Spanish, Czech and Catalan translations of the Bible were published between 1466 and 1492; in France, the Bible's abridged French versions gained popularity. Laypeople who read the Bible could challenge their priests' sermons, as it happened already in 1515. Completed by Jerome (d. 420),

ISO 8601 uses astronomical year numbering which includes a year 0 and negative numbers before it. Thus the ISO 8601 time line is −0001 , 0000, 0001, and 0002.

575-567: A "rhetoric of reform". Medieval examples include the Cluniac Reform in the 10th–11th centuries , and the 11th-century Gregorian Reform , both striving against lay influence over church affairs. When demanding a church reform, medieval authors mainly adopted a conservative and utopian approach, expressing their admiration for a previous "golden age" or "apostolic age" when the Church had allegedly been perfect and free of abuses. Both

The radical Hussites set up their own Church known as the Union of Bohemian Brethren . They rejected the separation of clergy and laity, and condemned all forms of violence and oath taking. Marshall writes that the Lollards, Hussites and conciliarist theologians "collectively give

805-406: A clear distinction between the supernatural and the human, Renaissance artists depicted God and the saints in a more human way. The institutional church was the reliable religious authority, through its bishops and priests, transmitting without error both apostolic tradition and the Bible, as interpreted by the decisions of ecumenical councils and by papal authority , through the mechanism of

920-407: A closely argued, 800-page volume. He would later defend his and Lilius's work against detractors. Clavius's opinion was that the correction should take place in one move, and it was this advice that prevailed with Gregory. The second component consisted of an approximation that would provide an accurate yet simple, rule-based calendar. Lilius's formula was a 10-day correction to revert the drift since

1035-572: A community of believers whose religious ideal—constantly aspired to if seldom attained—was peace and mutual love." The Catholic Church taught that entry into heaven required dying in a state of grace . Based on Christ's parable on the Last Judgement , the Church considered the performance of good works by the faithful, such as feeding the hungry and visiting the sick, as an important condition of salvation. Villagers and urban laypeople were frequently members of confraternities (such as

1150-623: A computation for the date of Easter that achieved the same result as Gregory's rules, without actually referring to him. Britain and the British Empire (including the eastern part of what is now the United States) adopted the Gregorian calendar in 1752. Sweden followed in 1753. Prior to 1917, Turkey used the lunar Islamic calendar with the Hijri era for general purposes and the Julian calendar for fiscal purposes. The start of

Apostolic tradition verified religious practices that some Protestant groups say had no explicit Biblical foundations, such as infant baptism . Latin was the language of public worship in most dioceses of Catholic Europe although few laypeople understood Latin. The Eucharist, the central element of liturgy ,

1380-714: A major schism within Western Christianity. It is considered one of the events that signified the end of the Middle Ages and the beginning of the early modern period in Europe. When the Reformation era ended is disputed among modern scholars. Prior to Martin Luther and other Protestant Reformers , there were earlier reform movements within Western Christianity. The Protestant Reformation, however,

Historian John Bossy (as summarized by Eamon Duffy) emphasized that "medieval Christianity had been fundamentally concerned with the creation and maintenance of peace in a violent world. “Christianity” in medieval Europe denoted neither an ideology nor an institution, but

1610-505: A protest (or dissent) against the edict of the Diet of Speyer (1529) , were the first individuals to be called Protestants. The edict reversed concessions made to the Lutherans with the approval of Holy Roman Emperor Charles V three years earlier . Europe experienced a period of dreadful calamities from the early 14th century . These culminated in a devastating pandemic known as

1725-525: A special emphasis on the education of laypeople. A leader of the movement the Dutch Wessel Gansfort (d. 1489) attacked abuses of indulgences. As the manufacturing of paper from rags and the printing machine with movable type were spreading in Europe, books could be bought at a reasonable price from the 15th century . Demand for religious literature was especially high. The German inventor Johannes Gutenberg (d. 1468) first published

1840-610: A theology professor at the University of Wittenberg in Saxony. Born into a middle-class family, Luther entered an Augustinian monastery after a heavy thunderstorm dreadfully reminded him the risk of sudden death and eternal damnation, but his anxiety about his sinfulness did not abate. His studies on the works of the Late Roman theologian Augustine of Hippo (d. 430) convinced him that those whom God chose as his elect received

1955-425: Is ⁠365 + 97 / 400 ⁠ days = 365.2425 days, or 365 days, 5 hours, 49 minutes and 12 seconds. The Gregorian calendar was a reform of the Julian calendar. It was instituted by papal bull Inter gravissimas dated 24 February 1582 by Pope Gregory XIII, after whom the calendar is named. The motivation for the adjustment was to bring the date for the celebration of Easter to the time of year in which it

2070-473: Is 365.2425463 days. As the average length of a Julian year is 365.25 days, the Julian year is almost 11 minutes longer than the mean tropical year. The discrepancy results in a drift of about three days every 400 years. Lilius's proposal resulted in an average year of 365.2425 days (see Accuracy ). At the time of Gregory's reform there had already been a drift of 10 days since the Council of Nicaea, resulting in

2185-458: Is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull Inter gravissimas issued by Pope Gregory XIII , which introduced it as a modification of, and replacement for, the Julian calendar . The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating

2300-415: Is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and the early 20th century. In England , Wales , Ireland , and Britain's American colonies , there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded

2415-423: Is the year using astronomical year numbering , that is, use 1 − (year BC) for BC years. ⌊ x ⌋ {\displaystyle \left\lfloor {x}\right\rfloor } means that if the result of the division is not an integer it is rounded down to the nearest integer. The general rule, in years which are leap years in the Julian calendar but not the Gregorian, is: Up to 28 February in

2530-581: Is usually considered to have started on 31 October 1517 with the publication of the Ninety-five Theses , authored by Martin Luther. Over three years later, on 3 January 1521, Luther was excommunicated by Pope Leo X . On 25 May 1521, at the Diet of Worms , Luther was condemned by the Holy Roman Empire , which officially banned citizens from defending or propagating Luther's ideas. Luther survived after being declared an outlaw due to

2645-505: The Age of Exploration , Pope Alexander VI claimed the right to distribute the newly discovered lands between Spain and Portugal, and his decision was confirmed in the Treaty of Tordesillas in 1494. The Spanish and Portuguese conquests and developing trade networks contributed to the global expansion of Catholicism. The popes were generous patrons of art and architecture. Julius II ordered

The faithful made pilgrimages to saints' shrines , but the proliferation in the saints' number undermined their reputation. Church buildings were richly decorated with paintings, sculptures, and stained glass windows. While Romanesque and Gothic art made

2875-924: The Battle of Agincourt is universally considered to have been fought on 25 October 1415 which is Saint Crispin 's Day. Usually, the mapping of new dates onto old dates with a start of year adjustment works well with little confusion for events that happened before the introduction of the Gregorian calendar. But for the period between the first introduction of the Gregorian calendar on 15 October 1582 and its introduction in Britain on 14 September 1752, there can be considerable confusion between events in continental western Europe and in British domains in English language histories. Events in continental western Europe are usually reported in English language histories as happening under

2990-477: The Black Death which hit Europe, killing about one third of the population. Around 1500, the population of Europe was about 60–85 million people—no more than 75 percent of the mid-14th-century demographic maximum. Due to a shortage of workforce, the landlords began to restrict the rights of their tenants which led to rural revolts that often ended with a compromise. The constant fear of unexpected death

3105-518: The Catholic countries of Europe and their overseas possessions. Over the next three centuries, the Protestant and Eastern Orthodox countries also gradually moved to what they called the " Improved calendar ", with Greece being the last European country to adopt the calendar (for civil use only) in 1923. However, many Orthodox churches continue to use the Julian calendar for religious rites and

3220-616: The College of Cardinals developed into the Western Schism (1378-1417) when his opponents declared his election invalid and proclaimed the French Clement VII ( r.  1378–1394 ) pope. Clement returned to Avignon, establishing a rival line of popes who were considered as antipopes by their opponents. When taking sides between the two popes, church leaders mainly accepted the local ruler's decision, which weakened

3335-555: The Council of Trent authorised Pope Paul III to reform the calendar, requiring that the date of the vernal equinox be restored to that which it held at the time of the First Council of Nicaea in 325 and that an alteration to the calendar be designed to prevent future drift. This would allow for more consistent and accurate scheduling of the feast of Easter. In 1577, a Compendium was sent to expert mathematicians outside

3450-562: The Eucharist , and priestly ordination as the seven sacraments of the Catholic Church . Women were not ordained priests but could live as nuns in convents after taking the three monastic vows of poverty, chastity, and obedience . The authority of the papacy was based on a well-organised system of communication and bureaucracy. The popes claimed the power of binding and loosing that Christ had reportedly granted to Peter

3565-585: The First Council of Nicaea in AD 325, the excess leap days introduced by the Julian algorithm had caused the calendar to drift such that the March equinox was occurring well before its nominal 21 March date. This date was important to the Christian churches because it is fundamental to the calculation of the date of Easter . To reinstate the association, the reform advanced the date by 10 days: Thursday 4 October 1582

3680-470: The Nicene Creed in 325. Its Western text contained a unilateral addition which contributed to the schism between Catholicism and Eastern Orthodoxy . The Creed contained the dogma of Trinity about one God uniting three equal persons: Father , Son , and Holy Spirit . Church authorities acknowledged that an individual might exceptionally receive direct revelations from God but maintained that

Pope Alexander VI ( r.  1492–1503 ) appointed his relatives , among them his own illegitimate sons to high offices.

Towards the end of the Renaissance , the Reformation marked the beginning of Protestantism and in turn resulted in

4025-576: The Radical Reformation , and the Catholic Reformation . Historian John Bossy criticized the term Reformation for "wrongly implying that bad religion was giving way to good," but also because it has "little application to actual social behaviour and little or no sensitivity to thought, feeling or culture." Some historians have also suggested a persisting Erasmian Reformation . Anglican theologian Alister McGrath explains

4140-537: The Roman Republic and the Roman Empire was the consular year, which began on the day when consuls first entered office—probably 1 May before 222 BC, 15 March from 222 BC and 1 January from 153 BC. The Julian calendar, which began in 45 BC, continued to use 1 January as the first day of the new year . Even though the year used for dates changed, the civil year always displayed its months in

4255-501: The rediscovery of the Ancient Greek philosopher Plato ( 347/348 BC ). Plato's ideas about an ultimate reality lying beyond visible reality posed a serious challenge to scholastic theologians' rigorous definitions. Textual criticism called into question the reliability of some of the fundamental texts of papal privilege: humanist scholars, like Nicholas of Cusa (d. 1464) proved that one of the basic documents of papal authority,

4370-650: The sacraments and liturgy . Western and Eastern Christians believed that the sacramental bread and wine of the Eucharist changed into the Body and Blood of Christ , though not in outward appearance. This belief, formulated as " transubstantiation ", was declared a Catholic dogma in 1215. From the 12th and 13th centuries, laypeople only received the bread during the Eucharist . The ecumenical councils' decisions were binding to all Catholics. The crucial elements of mainstream Christianity had been first summarised in

The rule for leap years is: Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the year 2000 is. There were two reasons to establish

The Reformation in Germanic countries was instigated by Martin Luther, however historians note that many of his ideas were pre-dated by Wycliff, Huss, Erasmus , Zwingli and others, both heretic and orthodox. Pope Leo X ( r.  1513–1521 ) decided to complete the construction of the new St. Peter's Basilica in Rome. As

4945-460: The Council of Nicaea was corrected by a deletion of 10 days. The Julian calendar day Thursday, 4 October 1582 was followed by the first day of the Gregorian calendar, Friday, 15 October 1582 (the cycle of weekdays was not affected). A month after having decreed the reform, the pope (with a brief of 3 April 1582) granted to one Antoni Lilio the exclusive right to publish the calendar for a period of ten years. The Lunario Novo secondo la nuova riforma

5060-401: The Council of Nicaea, and the imposition of a leap day in only 97 years in 400 rather than in 1 year in 4. The proposed rule was that "years divisible by 100 would be leap years only if they were divisible by 400 as well". The 19-year cycle used for the lunar calendar required revision because the astronomical new moon was, at the time of the reform, four days before the calculated new moon. It

5175-531: The Eucharist was to be administered sub utraque specie ('in both kinds') to the laity. The most radical Hussites, called Taborites after their new town of Tábor , held their property in common. Their millenarianism shocked the Utraquists who destroyed them in the Battle of Lipany in 1434. By this time, the remaining Catholic communities in Bohemia were almost exclusively German-speaking. The lack of

Astronomers avoid this ambiguity by the use of the Julian day number . For dates before the year 1, unlike the proleptic Gregorian calendar used in the international standard ISO 8601 , the traditional proleptic Gregorian calendar (like the older Julian calendar) does not have

5520-412: The Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes . Second, in the years since

5635-606: The Gregorian calendar. For example, the Battle of Blenheim is always given as 13 August 1704. Confusion occurs when an event affects both. For example, William III of England set sail from the Netherlands on 11 November 1688 (Gregorian calendar) and arrived at Brixham in England on 5 November 1688 (Julian calendar). Shakespeare and Cervantes seemingly died on exactly the same date (23 April 1616), but Cervantes predeceased Shakespeare by ten days in real time (as Spain used

5750-520: The Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so. To accommodate the two calendar changes, writers used dual dating to identify a given day by giving its date according to both styles of dating. For countries such as Russia where no start of year adjustment took place, O.S. and N.S. simply indicate the Julian and Gregorian dating systems. Many Eastern Orthodox countries continue to use

5865-605: The Reformation started when the Swiss priest Huldrych Zwingli (d. 1531) first preached against abuses in the Church in 1516. The end date of the Reformation is even more disputed, with 25 September 1555 (when the Peace of Augsburg was accepted), 23 May 1618, and 24 October 1648 (when the Thirty Years' War began and ended, respectively) being the most commonly mentioned terminuses. The Reformation has always been presented as one of

5980-803: The Vulgate contained the Septuagint version of the Old Testament . The systematic study of Biblical manuscripts revealed that Jerome had sometimes misinterpreted his sources of translation. A series of Latin-Greek editions of the New Testament was completed by the Dutch humanist Erasmus (d. 1536). These new Latin translations challenged the scriptural proof texts for some Catholic dogmas. After Arianism —a Christological doctrine condemned as heresy at ecumenical councils—disappeared in

6095-431: The absent priests' deputies were often poorly educated and underpaid. The clergy consisted of two major groups, the regular clergy and the secular clergy . Regular clerics lived under a monastic rule within the framework of a religious order ; secular clerics were responsible for pastoral care. The Church was a hierarchical organisation. The pope was elected by high-ranking clergymen, the cardinals , and assisted by

6210-489: The allegedly 4th-century Donation of Constantine was a medieval forgery. New religious movements promoted the deeper involvement of laity in religious practices. The Brethren of the Common Life dissuaded their members' priestly ordination and often placed their houses under the protection of urban authorities. They were closely associated with the devotio moderna , a new method of Catholic spirituality with

6325-483: The architect of the Gregorian calendar, noted that the tables agreed neither on the time when the Sun passed through the vernal equinox nor on the length of the mean tropical year. Tycho Brahe also noticed discrepancies. The Gregorian leap year rule (97 leap years in 400 years) was put forward by Petrus Pitatus of Verona in 1560. He noted that it is consistent with the tropical year of the Alfonsine tables and with

6440-430: The calendar being converted from , add one day less or subtract one day more than the calculated value. Give February the appropriate number of days for the calendar being converted into . When subtracting days to calculate the Gregorian equivalent of 29 February (Julian), 29 February is discounted. Thus if the calculated value is −4 the Gregorian equivalent of this date is 24 February. The year used in dates during

6555-644: The campaign, applied unusually aggressive marketing methods. A slogan attributed to him famously claimed that "As soon as the coin into the box rings, a soul from purgatory to heaven springs". Frederick the Wise , Prince-elector of Saxony ( r.  1486–1525 ) forbade the campaign because the Sacrosanctis suspended the sale of previous indulgences, depriving him of revenues that he had spent on his collection of relics . The campaign's vulgarity shocked many serious-minded believers, among them Martin Luther,

6670-518: The change a few months later: 9 December was followed by 20 December. Many Protestant countries initially objected to adopting a Catholic innovation; some Protestants feared the new calendar was part of a plot to return them to the Catholic fold. For example, the British could not bring themselves to adopt the Catholic system explicitly: the Annexe to their Calendar (New Style) Act 1750 established

6785-479: The clerics' monopoly of public ministry, and allowed all trained members of their community, men and women alike, to preach. The Western Schism reinforced a general desire for church reform. The Oxford theologian John Wycliffe (d. 1384) was one of the most radical critics. He attacked pilgrimages, the veneration of saints, and the doctrine of transubstantiation. He regarded the Church as an exclusive community of those chosen by God to salvation, and argued that

6900-498: The dating of major feasts. To unambiguously specify a date during the transition period (in contemporary documents or in history texts), both notations were given , tagged as 'Old Style' or 'New Style' as appropriate. During the 20th century, most non- Western countries also adopted the calendar, at least for civil purposes . The Gregorian calendar, like the Julian calendar , is a solar calendar with 12 months of 28–31 days each. The year in both calendars consists of 365 days, with

7015-470: The demolition of the ruined 4th-century St. Peter's Basilica in preparation for the building of a new Renaissance basilica . The necessity of a church reform in capite et membris ('in head and limbs') was frequently discussed at the ecumenical councils from the late 13th century . However, most stakeholders—popes, prelates and kings—preferred the status quo because they did not want to lose privileges or revenues. The system of papal dispensations

In contrast, Duns Scotus (d. 1308) and Gregory of Rimini (d. 1358) argued that an individual's choice could not influence God's decision; Rimini also asserted that God predestined the fate of both the saved and the damned. Justification before God and the timing of grace was also the subject of controversy. Many theologians such as Scotus, Ockham, and Gabriel Biel (d. 1495) taught that God established rules how

Other prelates might be regents or the power behind the throne. Believers were expected to pay the tithe (one tenth of their income) to the Church. Pluralism—the practice of holding multiple Church offices (or benefices )—was not unusual. This led to non-residence, and

Ashvin also stands for the divine twins , the Ashvins , the gods of vision, Ayurvedic medicine , the glow of sunrise and sunset, and the aversion of misfortune and sickness in Hindu mythology . Asawin is the Thai variant of Ashvin and stands for the warrior. The term is often translated into English as "knight". The Ashvins are described as representing

7475-417: The extra day at the end of the month of February, adding a 29 February for the leap day. Before the 1969 revision of its General Roman Calendar , the Catholic Church delayed February feasts after the 23rd by one day in leap years; masses celebrated according to the previous calendar still reflect this delay. Gregorian years are identified by consecutive year numbers. A calendar date is fully specified by

7590-449: The faithful could gain divine grace. Other theologians such as Rimini, and Hugolino of Orvieto (d. 1374) proposed that no one could deserve divine favour without God's direct intercession. Western Christianity displayed a remarkable unity. This was the outcome of the Gregorian Reform that established papal supremacy over the Catholic Church , and achieved the legal separation of the Catholic clergy from laity . Clerical celibacy

7705-419: The fiscal year was eventually fixed at 1 March and the year number was roughly equivalent to the Hijri year (see Rumi calendar ). As the solar year is longer than the lunar year this originally entailed the use of "escape years" every so often when the number of the fiscal year would jump. From 1 March 1917 the fiscal year became Gregorian, rather than Julian. On 1 January 1926, the use of the Gregorian calendar

7820-423: The increasing divergence between the canonical date of the equinox and observed reality. Easter is celebrated on the Sunday after the ecclesiastical full moon on or after 21 March, which was adopted as an approximation to the March equinox. European scholars had been well aware of the calendar drift since the early medieval period. Bede , writing in the 8th century, showed that the accumulated error in his time

7935-471: The issues that would soon come to the fore. A new intellectual movement known as Humanism emerged in the Late Middle Ages . The Humanists' slogan ad fontes ! ('back to the sources!') demonstrated their enthusiasm for Classical texts and textual criticism . The rise of the Ottoman Empire led to the mass immigration of Byzantine scholars to Western Europe, and many of them brought manuscripts previously unknown to western scholarship. This led to

8050-442: The late 7th century , no major disputes menaced the theological unity of the Western Church. Religious enthusiasts could organise their followers into nonconformist groups but they disbanded after their founder died. The Waldensians were a notable exception. Due to their efficient organisation, they survived not only the death of their founder Peter Waldo (d. c. 1205), but also a series of anti-heretic crusades . They rejected

8165-455: The law of the Catholic Church in 1582, but it was not recognised by Protestant Churches , Eastern Orthodox Churches , Oriental Orthodox Churches , and a few others. Consequently, the days on which Easter and related holidays were celebrated by different Christian Churches again diverged. On 29 September 1582, Philip II of Spain decreed the change from the Julian to the Gregorian calendar. This affected much of Roman Catholic Europe, as Philip

8280-642: The lie to any suggestion that torpor and complacency were the hallmarks of religious life in the century before Martin Luther." Historians customarily refer to Wycliffe and Hus as "Forerunners of the Reformation". The two reformers' emphasis on the Bible is often regarded as an early example of one of the basic principles of the Reformation—the idea sola scriptura ('by the Scriptures alone'), although prominent scholastic theologians were also convinced that Scripture, interpreted reasonably and in accord with

8510-453: The most crucial episodes of the early modern period, or even regarded as the event separating the modern era from the Middle Ages . The term Protestant, though initially purely political in nature, later acquired a broader sense, referring to a member of any Western church that subscribed to the main Reformation (or anti-Catholic ) principles . Six princes of the Holy Roman Empire and rulers of fourteen Imperial Free Cities , who issued

8625-402: The most solemn of forms available to the Church, the bull had no authority beyond the Catholic Church (of which he was the supreme religious authority) and the Papal States (which he personally ruled). The changes that he was proposing were changes to the civil calendar, which required adoption by the civil authorities in each country to have legal effect. The bull Inter gravissimas became

8740-475: The new year was moved to 1 September. In common usage, 1 January was regarded as New Year's Day and celebrated as such, but from the 12th century until 1751 the legal year in England began on 25 March ( Lady Day ). So, for example, the Parliamentary record lists the execution of Charles I on 30 January as occurring in 1648 (as the year did not end until 24 March), although later histories adjust

8855-524: The norm, can be identified. In other countries, the customs varied, and the start of the year moved back and forth as fashion and influence from other countries dictated various customs. Neither the papal bull nor its attached canons explicitly fix such a date, though the latter states that the " Golden number " of 1752 ends in December and a new year (and new Golden number) begins in January 1753. During

8970-470: The number of leap years in four centuries from 100 to 97, by making three out of four centurial years common instead of leap years. He also produced an original and practical scheme for adjusting the epacts of the Moon when calculating the annual date of Easter, solving a long-standing obstacle to calendar reform. Ancient tables provided the Sun's mean longitude. The German mathematician Christopher Clavius ,

9085-451: The older Julian calendar for religious purposes. Extending the Gregorian calendar backwards to dates preceding its official introduction produces a proleptic calendar , which should be used with some caution. For ordinary purposes, the dates of events occurring prior to 15 October 1582 are generally shown as they appeared in the Julian calendar, with the year starting on 1 January, and no conversion to their Gregorian equivalents. For example,

9200-621: The order January to December from the Roman Republican period until the present. During the Middle Ages, under the influence of the Catholic Church, many Western European countries moved the start of the year to one of several important Christian festivals—25 December ( Christmas ), 25 March ( Annunciation ), or Easter, while the Byzantine Empire began its year on 1 September and Russia did so on 1 March until 1492 when

9315-725: The papacy as a precondition for salvation . A year later, French troops arrested him, and in 1309, the seat of the papacy was transferred from the chaotic Rome to Avignon . During the period of the Avignon Papacy , the popes assumed control of the appointment of all senior Catholic clerics. The appointees had to pay fees and other contributions to the Roman Curia. The idea that Rome was the legitimate center of Catholicism never ceased, with Pope Gregory XI ( r.  1370–1378 ) returning to Rome. However, conflict between his successor Urban VII ( r.  1378–1389 ) and

9430-454: The period between 1582, when the first countries adopted the Gregorian calendar, and 1923, when the last European country adopted it, it was often necessary to indicate the date of some event in both the Julian calendar and in the Gregorian calendar, for example, "10/21 February 1750/51", where the dual year accounts for some countries already beginning their numbered year on 1 January while others were still using some other date. Even before 1582,

9545-434: The popes owed obedience to the ecumenical councils . This idea known as conciliarism was condemned by Pope Pius II ( r.  1458–1467 ) in a papal bull , but ecclesiastic and secular leaders often referred to it during their conflicts with the papacy. Relationships between the papacy and powerful Catholic rulers were regulated in special agreements known as concordats , limiting papal authority. As princes of

9660-454: The precision of observations towards the end of the 15th century made the question more pressing. Numerous publications over the following decades called for a calendar reform, among them two papers sent to the Vatican by the University of Salamanca in 1515 and 1578, but the project was not taken up again until the 1540s, and implemented only under Pope Gregory XIII (r. 1572–1585). In 1545,

9775-517: The professional staff of the Roman Curia . Secular clerics were organised into territorial units known as dioceses , each ruled by a bishop or archbishop . Each diocese was divided into parishes headed by parish priests who administered most sacraments to the faithful. These were sacred rites thought to transfer divine grace to humankind. The Council of Florence declared baptism , confirmation , marriage , extreme unction , penance ,

9890-573: The protection of Elector Frederick the Wise . The spread of Gutenberg's printing press provided the means for the rapid dissemination of religious materials in the vernacular. The initial movement in Germany diversified, and nearby other reformers such as Huldrych Zwingli and John Calvin with different theologies arose. In general, the Reformers argued that salvation in Christianity

10005-485: The reform commission for comments. Some of these experts, including Giambattista Benedetti and Giuseppe Moleto , believed Easter should be computed from the true motions of the Sun and Moon, rather than using a tabular method, but these recommendations were not adopted. The reform adopted was a modification of a proposal made by the Calabrian doctor Aloysius Lilius (or Lilio). Lilius's proposal included reducing

10120-526: The resistance of autonomous institutions such as cathedral chapters . Neither could they exercise authority over non-resident clerics who had received their benefice from the papacy. On the eve of the Reformation, the Fifth Council of the Lateran was the last occasion when efforts to introduce a far-reaching reform from above could have achieved but it was dissolved in 1517 without making decisions on

10235-405: The sale of certificates of indulgences had been a well-established method of papal fund raising, he announced new indulgences in the papal bull Sacrosanctis in 1515. On the advice of the banker Jakob Fugger (d. 1525), he appointed the pluralist prelate Albert of Brandenburg (d. 1545) to supervise the sale campaign in Germany. The Dominican friar Johann Tetzel (d. 1519), a leading figure in

10350-410: The same basis, for years before 1582), and the difference between Gregorian and Julian calendar dates increases by three days every four centuries (all date ranges are inclusive). The following equation gives the number of days that the Gregorian calendar is ahead of the Julian calendar, called the "secular difference" between the two calendars. A negative difference means the Julian calendar is ahead of

10465-399: The same day, it took almost five centuries before virtually all Christians achieved that objective by adopting the rules of the Church of Alexandria (see Easter for the issues which arose). Because the date of Easter is a function – the computus  – of the date of the spring equinox in the northern hemisphere, the Catholic Church considered unacceptable

10580-525: The same to two sexagesimal places (0;14,33, equal to decimal 0.2425) and this is also the mean length of the Gregorian year. Thus Pitatus's solution would have commended itself to the astronomers. Lilius's proposals had two components. First, he proposed a correction to the length of the year. The mean tropical year is 365.24219 days long. A commonly used value in Lilius's time, from the Alfonsine tables,

10695-505: The start of the year to 1 January and record the execution as occurring in 1649. Most Western European countries changed the start of the year to 1 January before they adopted the Gregorian calendar. For example, Scotland changed the start of the Scottish New Year to 1 January in 1600 (this means that 1599 was a short year). England, Ireland and the British colonies changed the start of the year to 1 January in 1752 (so 1751

10810-607: The starting and ending date of the Reformation have always been debated. The most commonly used starting date is 31 October 1517—the day when the German theologian Martin Luther (d. 1546) allegedly nailed up a copy of his disputation paper on indulgences and papal power known as the Ninety-five Theses to the door of the castle church in Wittenberg in Electoral Saxony . Calvinist historians often propose that

10925-493: The state could seize the corrupt clerics' endowments. Known as Lollards , Wycliffe's followers rejected clerical celibacy and the grant of indulgences. The Parliament of England passed a law against heretics , but Lollard communities survived the purges. Wycliffe's theology had a marked impact on the Prague academic Jan Hus (d. 1415). He delivered popular sermons against the clerics' wealth and temporal powers, for which he

11040-480: The supranational character of the Catholic Church. In 1409, cardinals from both sides elected a new pope at the Council of Pisa but his two rivals refused to resign. More prudent preparations paved the way for the Council of Constance . Here, one of the three popes resigned, his two rivals were deposed, and the newly elected Martin V ( r.  1417–1431 ) was acknowledged as the legitimate pope throughout Catholic Europe. The Council of Constance declared that

11155-403: The term "Reformation" as "an interpretative category—a way of mapping out a slice of history in which certain ideas, attitudes, and values were developed, explored, and applied". The historian Peter Marshall emphasizes that the "call for 'reform' within Christianity is about as old as the religion itself, and in every age there have been urgent attempts to bring it about". Charlemagne employed

11270-427: The vernal equinox falling on 10 or 11 March instead of the ecclesiastically fixed date of 21 March, and if unreformed it would have drifted further. Lilius proposed that the 10-day drift should be corrected by deleting the Julian leap day on each of its ten occurrences over a period of forty years, thereby providing for a gradual return of the equinox to 21 March. Lilius's work was expanded upon by Christopher Clavius in

11385-612: The year (numbered according to a calendar era , in this case Anno Domini or Common Era ), the month (identified by name or number), and the day of the month (numbered sequentially starting from 1). Although the calendar year currently runs from 1 January to 31 December, at previous times year numbers were based on a different starting point within the calendar (see the "beginning of the year" section below). Calendar cycles repeat completely every 400 years, which equals 146,097 days. Of these 400 years, 303 are regular years of 365 days and 97 are leap years of 366 days. A mean calendar year

11500-432: The year sometimes had to be double-dated because of the different beginnings of the year in various countries. Woolley, writing in his biography of John Dee (1527–1608/9), notes that immediately after 1582 English letter writers "customarily" used "two dates" on their letters, one OS and one NS. "Old Style" (O.S.) and "New Style" (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this

11615-540: Was a completed status based on faith in Jesus alone and not a process that could involve good works , as in the Catholic view. Protestantism also introduced new ecclesiology . The Counter-Reformation was the Catholic reform efforts initiated in response to the Protestant Reformation and its causes. In the 16th-century context, the term mainly covers four major movements: Lutheranism , Calvinism ,

11730-528: Was a principal obstacle to the implementation of reform measures, as the Holy See regularly granted immunities to those who did not want to execute them. Within regular clergy, the so-called " congregations of strict observance" spread. These were monastic communities that returned to the strict interpretation of their order's rule. Reformist bishops tried to discipline their clergy through regular canonical visitations but their attempts mainly failed due to

11845-479: Was a short year with only 282 days). Later in 1752 in September the Gregorian calendar was introduced throughout Britain and the British colonies (see the section Adoption ). These two reforms were implemented by the Calendar (New Style) Act 1750 . In some countries, an official decree or law specified that the start of the year should be 1 January. For such countries, a specific date when a "1 January year" became

11960-650: Was also celebrated in Latin. Catholics regarded the Vulgate as the Bible's authentic Latin translation. Commentators applied several methods of interpretations to resolve contradictions between Bible texts. In the universities, scholastic theology held sway. Legitimate debates among scholastic theologians were not uncommon. Predestination —God's decision about an individual's fate in afterlife—was frequently discussed. Ockhamist theologians taught that God destined to salvation those about whom foreknew that they would accept

12075-462: Was also growing, and witch-hunts intensified. From the end of the 15th century , a new, sexually transmitted infection spread in Europe. This was syphilis that destroyed its victims' looks with ulcers and scabs before killing them. Along with the French invasion of Italy , the syphilis gave the background to the success of the charismatic preacher Girolamo Savonarola (d. 1498) who called for

12190-642: Was at the time ruler over Spain and Portugal as well as much of Italy . In these territories, as well as in the Polish–Lithuanian Commonwealth and in the Papal States, the new calendar was implemented on the date specified by the bull, with Julian Thursday, 4 October 1582, being followed by Gregorian Friday, 15 October. The Spanish and Portuguese colonies followed somewhat later de facto because of delay in communication. The other major Catholic power of Western Europe, France, adopted

12305-457: Was celebrated when it was introduced by the early Church. The error in the Julian calendar (its assumption that there are exactly 365.25 days in a year) had led to the date of the equinox according to the calendar drifting from the observed reality, and thus an error had been introduced into the calculation of the date of Easter . Although a recommendation of the First Council of Nicaea in 325 specified that all Christians should celebrate Easter on

12420-404: Was extended to include use for general purposes and the number of the year became the same as in most other countries. This section always places the intercalary day on 29 February even though it was always obtained by doubling 24 February (the bissextum (twice sixth) or bissextile day) until the late Middle Ages . The Gregorian calendar is proleptic before 1582 (calculated backwards on

12535-415: Was followed by Friday 15 October 1582. In addition, the reform also altered the lunar cycle used by the Church to calculate the date for Easter, because astronomical new moons were occurring four days before the calculated dates. Whilst the reform introduced minor changes, the calendar continued to be fundamentally based on the same geocentric theory as its predecessor. The reform was adopted initially by

12650-408: Was mirrored by popular artistic motifs, such as the allegory of danse macabre ('dance of death'). The fear also contributed to the growing popularity of Masses for the dead . Already detectable among early Christians , these ceremonies indicated a widespread belief in purgatory —a transitory state for souls that needed purification before entering heaven . Fear of malevolent magical practice

12765-482: Was more than three days. Roger Bacon in c.  1200 estimated the error at seven or eight days. Dante , writing c.  1300 , was aware of the need for calendar reform. An attempt to go forward with such a reform was undertaken by Pope Sixtus IV , who in 1475 invited Regiomontanus to the Vatican for this purpose. However, the project was interrupted by the death of Regiomontanus shortly after his arrival in Rome. The increase of astronomical knowledge and

12880-404: Was printed by Vincenzo Accolti, one of the first calendars printed in Rome after the reform, notes at the bottom that it was signed with papal authorization and by Lilio ( Con licentia delli Superiori... et permissu Ant(onii) Lilij ). The papal brief was revoked on 20 September 1582, because Antonio Lilio proved unable to keep up with the demand for copies. Although Gregory's reform was enacted in

12995-487: Was reinforced through the prohibition of clerical marriage ; ecclesiastical courts were granted exclusive jurisdiction over clerics, and also over matrimonial causes. Priests were ordained by bishops in accordance with the principle of apostolic succession —a claim to the uninterrupted transmission of their consecrating power from Christ's Apostles through generations of bishops. Bishops, abbots , abbesses , and other prelates might possess remarkable wealth. Some of

13110-539: Was summoned to the Council of Constance. Although the German king Sigismund of Luxemburg ( r.  1410–1437 ) had granted him safe conduct, Hus was sentenced to death for heresy and burned at the stake on 6 July 1415. His execution led to a nationwide religious movement in Bohemia , and the papacy called for a series of crusades against Hus's followers. The moderate Hussites , mainly Czech aristocrats and academics, were known as Utraquists for they taught that

13225-412: Was to be corrected by one day every 300 or 400 years (8 times in 2500 years) along with corrections for the years that are no longer leap years (i.e. 1700, 1800, 1900, 2100, etc.) In fact, a new method for computing the date of Easter was introduced. The method proposed by Lilius was revised somewhat in the final reform. When the new calendar was put in use, the error accumulated in the 13 centuries since
