84-771: Many of the students are participants of all kinds of the city, national and international Olympiads , contests, conferences and competitions. The gymnasium is usually involved in international projects such as the MUN project with its annual international conferences, the Russian-Finnish project “ICT-based Education as a Driver of Change in Learning”, the International Science Olympiad and others; cultural exchange programmes, international festivals and competitions. Apart from Russia's basic curriculum,

168-514: A 27- or 28-day intercalary month , the Mensis Intercalaris , was sometimes inserted between February and March. This intercalary month was formed by inserting 22 or 23 days after the first 23 days of February; the last five days of February, which counted down toward the start of March, became the last five days of Intercalaris. The net effect was to add 22 or 23 days to the year, forming an intercalary year of 377 or 378 days. Some say

252-523: A common year and the 25th to 29th in a leap year). Hence he regarded the bissextum as the first half of the doubled day. All later writers, including Macrobius about 430, Bede in 725, and other medieval computists (calculators of Easter) followed this rule, as does the liturgical calendar of the Roman Catholic Church. However, Celsus' definition continued to be used for legal purposes. It was incorporated into Justinian's Digest , and in

336-517: A corruption of Winnimanoth "pasture-month"), Brachmanoth (" fallow -month"), Heuuimanoth ("hay month"), Aranmanoth (" reaping month"), Witumanoth ("wood month"), Windumemanoth ("vintage month"), Herbistmanoth ("harvest month"), and Heilagmanoth ("holy month"). The calendar month names used in western and northern Europe, in Byzantium, and by the Amazigh (Berbers) , were derived from

420-561: A four year period. For example, the first year of Olympiad 140 began in the summer of 220  BC and lasted until the middle of 219  BC . After the 2nd, 3rd, and 4th years of Olympiad 140, the games in the summer of 216  BC would begin the first year of Olympiad 141. The sophist Hippias was the first writer to compile a comprehensive list of the Olympic victors ( ολυμπιονίκες , olympioníkes ). Although his Olympic Record ( Ὀλυμπιονικῶν Ἀναγραφή , Olympionikō̂n Anagraphḗ )

504-489: A large number of festivals were decreed to celebrate events of dynastic importance, which caused the character of the associated dates to be changed to NP . However, this practice was discontinued around the reign of Claudius , and the practice of characterising days fell into disuse around the end of the first century AD: the Antonine jurist Gaius speaks of dies nefasti as a thing of the past. The old intercalary month

588-487: A leap year of 366 days. They follow a simple cycle of three normal years and one leap year, giving an average year that is 365.25 days long. That is more than the actual solar year value of approximately 365.2422 days (the current value, which varies), which means the Julian calendar gains one day every 129 years. In other words, the Julian calendar gains 3.1 days every 400 years. Gregory's calendar reform modified

672-508: A long cruise on the Nile with Cleopatra before leaving the country in June 47 BC. Caesar returned to Rome in 46 BC and, according to Plutarch , called in the best philosophers and mathematicians of his time to solve the problem of the calendar. Pliny says that Caesar was aided in his reform by the astronomer Sosigenes of Alexandria who is generally considered the principal designer of

756-519: A peace, and a banquet was held to celebrate the event. Lucan depicted Caesar talking to a wise man called Acoreus during the feast, stating his intention to create a calendar more perfect than that of Eudoxus (Eudoxus was popularly credited with having determined the length of the year to be 365 + 1 ⁄ 4 days). But the war soon resumed and Caesar was attacked by the Egyptian army for several months until he achieved victory. He then enjoyed

840-435: A pontifex could lengthen a year in which he or one of his political allies was in office, or refuse to lengthen one in which his opponents were in power. Caesar's reform was intended to solve this problem permanently, by creating a calendar that remained aligned to the sun without any human intervention. This proved useful very soon after the new calendar came into effect. Varro used it in 37 BC to fix calendar dates for

924-552: A practical emphasis. The name was changed from Petrograd Second Gymnasium to the 1st Unified Labor School of the Kazansky district ; after that, the school was repeatedly renamed during the Soviet rule. In 1962 it was able to get a new status – profound study of English was introduced into curriculum, and that enabled the school's authorities to establish contacts with some schools abroad and start several exchanges programmes. In 1990

1008-536: A reform of the earlier Roman calendar , which was largely a lunisolar one. It took effect on 1 January 45 BC , by his edict . Caesar's calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years, until 1582 when Pope Gregory XIII promulgated a revised calendar. The Julian calendar has two types of years: a normal year of 365 days and

1092-428: A technical fashion to refer to the earlier of the two days, which requires the inscription to refer to the whole 48-hour day as the bissextile. Some later historians share this view. Others, following Mommsen , take the view that Celsus was using the ordinary Latin (and English) meaning of "posterior". A third view is that neither half of the 48-hour "bis sextum" was originally formally designated as intercalated, but that

1176-547: Is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Amazigh people (also known as the Berbers). The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar , as

1260-517: Is no basis for the statement sometimes seen that they were called " Undecimber " and " Duodecimber ", terms that arose in the 18th century over a millennium after the Roman Empire's collapse. Their individual lengths are unknown, as is the position of the Nones and Ides within them. Because 46 BC was the last of a series of irregular years, this extra-long year was, and is, referred to as

1344-466: Is now entirely lost, it apparently formed the basis of all later Olympic dating. By the time of Eratosthenes , his dating of Coroebus 's victory to 776  BC had been generally accepted. The panhellenic nature of the games, their regular schedule, and the improved victor list allowed Greek historians to use the Olympiads as a way of reckoning time that did not depend on the various calendars of

1428-594: Is sometimes extended further by media references to "Summer Olympiads". However, the IOC does not seem to make an official distinction between Olympiads for the summer and winter games, and such usage, particularly for the Winter Olympics, is inconsistent with the numbering discussed above. Some Olympic Committees often use the term quadrennium , which it claims refers to the same four-year period. However, it indicates these quadrennia in calendar years, starting with

1512-476: Is used to indicate a regular event of international competition for top achieving participants; it does not necessarily indicate a four-year period. In some languages, like Czech and Slovak , Olympiad ( Czech : olympiáda ) is the correct term for the games. The Olympiad ( L'Olimpiade ) is also the name of some 60 operas set in Ancient Greece. Julian calendar The Julian calendar

1596-577: The Chronicle of Eusebius . Though the games were held without interruption, on more than one occasion they were held by others than the Eleians . The Eleians declared such games Anolympiads (non-Olympics), but it is assumed the winners were nevertheless recorded. During the 3rd century , records of the games are so scanty that historians are not certain whether after 261 they were still held every four years. Some winners were recorded though, until

1680-732: The Egyptian calendar , a fixed year of 365 days was in use, drifting by one day against the sun in four years. An unsuccessful attempt to add an extra day every fourth year was made in 238 BC ( Decree of Canopus ). Caesar probably experienced this "wandering" or "vague" calendar in that country. He landed in the Nile delta in October 48 BC and soon became embroiled in the Ptolemaic dynastic war, especially after Cleopatra managed to be "introduced" to him in Alexandria . Caesar imposed

1764-551: The Hellenistic period that the first recorded Olympic contest was used as a calendar epoch . Ancient authors agreed that other Olympics had been held before the race won by Coroebus but disagreed on how many; the convention was established to place Coroebus's victory at a time equivalent to the summer of 776  BC in the Proleptic Julian calendar, and to treat it as Year 1 of Olympiad 1. Olympiad 2 began with

1848-793: The International Linguistics Olympiad and their associated national qualifying tests (e.g., the United States of America Mathematical Olympiad , the USA Forensics Olympiad or the United Kingdom Linguistics Olympiad ), and also events in mind-sports, such as the Science Olympiad , Mindsport Olympiad , Chess Olympiad , International History Olympiad and Computer Olympiad . In these cases Olympiad

1932-450: The Roman calendar . However, in the following decades many of the local civic and provincial calendars of the empire and neighbouring client kingdoms were aligned to the Julian calendar by transforming them into calendars with years of 365 days with an extra day intercalated every four years. The reformed calendars typically retained many features of the unreformed calendars. In many cases,

2016-540: The city-states . (See e.g. the Attic calendar of the Athenians .) The first to do so consistently was Timaeus of Tauromenium in the third century  BC . Nevertheless, since for events of the early history of the games the reckoning was used in retrospect, some of the dates given by later historian for events before the 5th century  BC are very unreliable. In the 2nd century , Phlegon of Tralles summarized

2100-527: The mensis intercalaris always had 27 days and began on either the first or the second day after the Terminalia (23 February). If managed correctly this system could have allowed the Roman year to stay roughly aligned to a tropical year . However, since the pontifices were often politicians, and because a Roman magistrate's term of office corresponded with a calendar year, this power was prone to abuse:

2184-745: The "Pentathlon of the Muses", as their purpose was to bring artists to present their work and compete for "art" medals across five categories: architecture, music, literature, sculpture and painting. Nowadays, while there are no competitions as such, cultural and artistic practice is displayed via the Cultural Olympiad. The 2010 Winter Olympics in Vancouver presented the Cultural Olympiad Digital Edition . The 2012 Olympics included an extensive Cultural Olympiad with

2268-411: The "last year of confusion". The new calendar began operation after the realignment had been completed, in 45 BC. The Julian months were formed by adding ten days to a regular pre-Julian Roman year of 355 days, creating a regular Julian year of 365 days. Two extra days were added to January, Sextilis (August) and December, and one extra day was added to April, June, September, and November. February

2352-516: The 293rd and last Olympiad of AD  393. In 394, Roman Emperor Theodosius I outlawed the games at Olympia as pagan. Though it would have been possible to continue the reckoning by just counting four-year periods, by the middle of the 5th century reckoning by Olympiads had ceased. The Summer Olympics are more correctly referred to as the Games of the Olympiad. The first poster to announce

2436-546: The 4th year of the 700th Olympiad begins roughly around 2 August 2024. In reference to the modern Olympics, their Olympiads are four year periods beginning on January 1 of the year of the Summer Games . Thus, the modern Olympiad I began 1 January 1896, Olympiad II began 1 January 1900, and so on. Olympiad XXXIII began 1 January 2024. Because the Julian and Gregorian calendars go directly from 1  BC to AD  1,

2520-425: The 7-day week in the first century AD, and dominical letters began to appear alongside nundinal letters in the fasti. The Julian calendar has two types of year: "normal" years of 365 days and "leap" years of 366 days. There is a simple cycle of three "normal" years followed by a leap year and this pattern repeats forever without exception. The Julian year is, therefore, on average 365.25 days long. Consequently,

The Asian calendar was an adaptation of the Ancient Macedonian calendar used in the Roman province of Asia and, with minor variations, in nearby cities and provinces. It is known in detail through the survival of decrees promulgating it issued in 8   BC by the proconsul Paullus Fabius Maximus . It renamed the first month Dios as Kaisar , and arranged

2688-483: The English Statute De Anno et Die Bissextili of 1236, which was not formally repealed until 1879. The effect of the bissextile day on the nundinal cycle is not discussed in the sources. According to Dio Cassius, a leap day was inserted in 41 BC to ensure that the first market day of 40 BC did not fall on 1 January, which implies that the old 8-day cycle was not immediately affected by

2772-790: The Games resumed in 1948 as the Games of the XIV Olympiad . However, the 1936 Winter Games were the IV Winter Olympic Games , and on the resumption of the Winter Games in 1948 , the event was designated the V Winter Olympic Games . The 2020 Summer Games were the Games of the XXXII Olympiad . On 24 March 2020, due to the COVID-19 pandemic , it was postponed to 2021 rather than cancelled, and thus becoming

Many notable university professors were invited to teach at the gymnasium, and its diplomas were considered on par with those of universities for public service employment. After 1917 the gymnasium became a co-ed school, and its focus steadily shifted to providing general education with

2940-560: The Julian reform. However, he also reports that in AD ;44, and on some previous occasions, the market day was changed to avoid a conflict with a religious festival. This may indicate that a single nundinal letter was assigned to both halves of the 48-hour bissextile day by this time, so that the Regifugium and the market day might fall on the same date but on different days. In any case, the 8-day nundinal cycle began to be displaced by

3024-539: The Julian rule, to reduce the average length of the calendar year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the solar year : the Gregorian calendar gains just 0.1 day over 400 years. For any given event during the years from 1901 through 2099, its date according to the Julian calendar is 13 days behind its corresponding Gregorian date (for instance Julian 1 January falls on Gregorian 14 January). Most Catholic countries adopted

3108-432: The Julian year drifts over time with respect to the tropical (solar) year (365.24217 days). Although Greek astronomers had known, at least since Hipparchus , a century before the Julian reform, that the tropical year was slightly shorter than 365.25 days, the calendar did not compensate for this difference. As a result, the calendar year gains about three days every four centuries compared to observed equinox times and

3192-578: The Latin names. However, in eastern Europe older seasonal month names continued to be used into the 19th century, and in some cases are still in use, in many languages, including: Belarusian , Bulgarian , Croatian , Czech , Finnish, Georgian , Lithuanian , Macedonian , Polish , Romanian , Slovene , Ukrainian . When the Ottoman Empire adopted the Julian calendar, in the form of the Rumi calendar,

3276-806: The London 2012 Festival in the host city, and events elsewhere including the World Shakespeare Festival produced by the RSC . The 2016 games' Cultural Olympiad was scaled back due to Brazil's recession ; there was no published programme, with director Carla Camurati promising "secret" and "spontaneous" events such as flash mobs . Cultural events in time for the 2020 Summer Olympics in Tokyo were planned before being canceled due to pandemic restrictions in Japan . Instead, an alternative virtual event

3360-474: The New Year was not on 1 January, the leap day was not on the traditional bissextile day , the old month names were retained, the lengths of the reformed months did not match the lengths of Julian months, and, even if they did, their first days did not match the first day of the corresponding Julian month. Nevertheless, since the reformed calendars had fixed relationships to each other and to the Julian calendar,

3444-624: The Olympic Games. From one Games to the next, the scale of the Cultural Olympiad varies considerably, sometimes involving activity over the entire Olympiad and other times emphasizing specific periods within it. Baron Pierre de Coubertin established the principle of Olympic Art Competitions at a special congress in Paris in 1906, and the first official programme was presented during the 1912 Games in Stockholm. These competitions were also named

3528-504: The Second Gymnasium provides an opportunity of extensive English and a second language (either German , Spanish , Chinese or French ) learning. The Gymnasium opened its doors on 7 September 1805 (it was named St. Petersburg Provincial Gymnasium back then). 96 pupils were admitted to the school on the opening day, but soon the number of students reached 400. Initially intended as a boarding school for boys of noble families,

3612-422: The beginning of the fifth. This error continued for thirty-six years by which time twelve intercalary days had been inserted instead of the number actually due, namely nine. But when this error was at length recognised, it too was corrected, by an order of Augustus, that twelve years should be allowed to pass without an intercalary day, since the sequence of twelve such years would account for the three days which, in

The octaeteris , a cycle of eight lunar years popularised by Cleostratus (and also commonly attributed to Eudoxus ) which was used in some early Greek calendars, notably in Athens , is 1.53 days longer than eight mean Julian years . The length of nineteen years in the cycle of Meton was 6,940 days, six hours longer than the mean Julian year. The mean Julian year

3780-595: The correct Julian calendar. Due to the confusion about this period, we cannot be sure exactly what day (e.g. Julian day number ) any particular Roman date refers to before March of 8 BC, except for those used in Egypt in 24   BC which are secured by astronomy. An inscription has been discovered which orders a new calendar to be used in the Province of Asia to replace the previous Greek lunar calendar. According to one translation Intercalation shall commence on

3864-464: The course of thirty-six years, had been introduced by the premature actions of the priests. So, according to Macrobius, Some people have had different ideas as to how the leap years went. The above scheme is that of Scaliger (1583) in the table below. He established that the Augustan reform was instituted in 8 BC. The table below shows for each reconstruction the implied proleptic Julian date for

3948-609: The cycle of modern Olympiads is ahead of the ancient cycle by one year. Each olympiad started with the holding of the games, which originally began on the first or second full moon after the summer solstice . After the introduction of the Metonic cycle about 432 BC, the start of the games was determined slightly differently. Within each olympiad, time was reckoned by referring to its 1st, 2nd, 3rd, or 4th year. Ancient writers sometimes describe their Olympiads as lasting five years but do so by counting inclusively ; in fact each comprised

4032-469: The date in both calendars was the same. The dates in the Alexandrian and Julian calendars are in one-to-one correspondence except for the period from 29 August in the year preceding a Julian leap year to the following 24 February. From a comparison of the astronomical data with the Egyptian and Roman dates, Alexander Jones concluded that the Egyptian astronomers (as opposed to travellers from Rome) used

4116-408: The day after 14 Peritius [a.d. IX Kal. Feb, which would have been 15 Peritius] as it is currently constituted in the third year following promulgation of the decree. Xanthicus shall have 32 days in this intercalary year. This is historically correct. It was decreed by the proconsul that the first day of the year in the new calendar shall be Augustus' birthday, a.d. IX Kal. Oct. Every month begins on

4200-407: The early Julian calendar. The earliest direct evidence is a statement of the 2nd century jurist Celsus , who states that there were two-halves of a 48-hour day, and that the intercalated day was the "posterior" half. An inscription from AD 168 states that a.d. V Kal. Mart. was the day after the bissextile day. The 19th century chronologist Ideler argued that Celsus used the term "posterior" in

4284-726: The ephemeral month names of the post-Augustan Roman emperors were the Old High German names introduced by Charlemagne . According to his biographer, Einhard, Charlemagne renamed all of the months agriculturally in German. These names were used until the 15th century, over 700 years after his rule, and continued, with some modifications, to be used as "traditional" month names until the late 18th century. The names (January to December) were: Wintarmanoth ("winter month"), Hornung , Lentzinmanoth ("spring month", " Lent month"), Ostarmanoth (" Easter month"), Wonnemanoth (" joy -month",

4368-463: The events of each Olympiad in a book called Olympiads ; fragments survive in the work of the Byzantine writer Photius . Christian chroniclers continued to use this Greek system of dating as a way of synchronizing biblical events with Greek and Roman history. In the 3rd century , Sextus Julius Africanus compiled a list of Olympic victors up to 217  BC , and this list has been preserved in

4452-479: The first day of Caesar's reformed calendar and the first Julian date on which the Roman calendar date matches the Julian calendar after the completion of Augustus' reform. By the systems of Scaliger, Ideler and Bünting, the leap years prior to the suspension happen to be BC years that are divisible by 3, just as, after leap year resumption, they are the AD years divisible by 4. Pierre Brind'Amour argued that "only one day

4536-538: The first postponement in the 124-year history of the Olympics. Some media people have from time to time referred to a particular (e.g., the n th) Winter Olympics as "the Games of the n th Winter Olympiad", perhaps believing it to be the correct formal name for the Winter Games by analogy with that of the Summer Games. Indeed, at least one IOC-published article has applied this nomenclature as well. This analogy

4620-661: The first year after the Summer Olympics and ending with the year the next Olympics are held. This would suggest a more precise period of four years, but, for example, the 2001–2004 Quadrennium would then not be exactly the same period as the XXVII Olympiad , which was 2000–2003. A Cultural Olympiad is a concept protected by the International Olympic Committee and may be used only within the limits defined by an Organizing Committee for

4704-543: The games using this term was the one for the 1932 Summer Olympics , in Los Angeles, using the phrase: Call to the games of the Xth Olympiad . The modern Olympiad is a period of four years: the first Olympiad started on 1 January 1896, and an Olympiad starts on 1 January of the years evenly divisible by four. This means that the count of the Olympiads continues, even if Olympic Games are cancelled: For instance,

4788-519: The insertion of a regular intercalary month in February. When Caesar decreed the reform, probably shortly after his return from the African campaign in late Quintilis (July), he added 67 more days by inserting two extraordinary intercalary months between November and December. These months are called Intercalaris Prior and Intercalaris Posterior in letters of Cicero written at the time; there

4872-460: The months such that each month started on the ninth day before the kalends of the corresponding Roman month; thus the year began on 23 September, Augustus's birthday. The first step of the reform was to realign the start of the calendar year (1 January) to the tropical year by making 46 BC 445 days long, compensating for the intercalations which had been missed during Caesar's pontificate. This year had already been extended from 355 to 378 days by

4956-461: The months. Macrobius states that the extra days were added immediately before the last day of each month to avoid disturbing the position of the established religious ceremonies relative to the Nones and Ides of the month. The inserted days were all initially characterised as dies fasti ( F – see Roman calendar ). The character of a few festival days was changed. In the early Julio-Claudian period

5040-459: The need to do so arose as the concept of a 48-hour day became obsolete. There is no doubt that the bissextile day eventually became the earlier of the two days for most purposes. In 238 Censorinus stated that it was inserted after the Terminalia (23 February) and was followed by the last five days of February, i.e., a.d. VI, V, IV, III and prid. Kal. Mart. (which would be 24 to 28 February in

5124-403: The new calendar immediately; Protestant countries did so slowly in the course of the following two centuries or so; most Orthodox countries retain the Julian calendar for religious purposes but adopted the Gregorian as their civil calendar in the early part of the twentieth century. The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition,

SECTION 60

#1732780214583

5208-399: The new calendar was much simpler than the pre-Julian calendar, the pontifices initially added a leap day every three years, instead of every four. There are accounts of this in Solinus, Pliny, Ammianus, Suetonius, and Censorinus. Macrobius gives the following account of the introduction of the Julian calendar: Caesar's regulation of the civil year to accord with his revised measurement

5292-479: The new one as 24 January, a.d. IX Kal. Feb 5 BC in the Julian calendar, which was a leap year. Thus from inception the dates of the reformed Asian calendar are in one-to-one correspondence with the Julian. Another translation of this inscription is Intercalation shall commence on the day after the fourteenth day in the current month of Peritius [a.d. IX Kal. Feb], occurring every third year. Xanthicus shall have 32 days in this intercalary year. This would move

5376-497: The next games in the summer of 772  BC . Thus, for N less than 195, Olympiad N is reckoned as having started in the year 780 − ( 4 × N ) {\displaystyle 780-(4\times N)}   BC and ended four years later. For N greater than or equal to 195, Olympiad N began in AD   ( 4 × N ) − 779 {\displaystyle (4\times N)-779} and ended four years later. By extrapolation,

5460-405: The ninth day before the kalends. The date of introduction, the day after 14 Peritius, was 1 Dystrus, the next month. The month after that was Xanthicus. Thus Xanthicus began on a.d. IX Kal. Mart., and normally contained 31 days. In leap year, however, it contained an extra "Sebaste day", the Roman leap day, and thus had 32 days. From the lunar nature of the old calendar we can fix the starting date of

5544-464: The official numbering of the Winter Olympics does not count Olympiads, it counts only the Games themselves. For example, the first Winter Games, in 1924 , are not designated as Winter Games of the VII Olympiad , but as the I Winter Olympic Games . (The first Winter Games were termed as "Olympic" in a later year.) The 1936 Summer Games were the Games of the XI Olympiad . After the 1940 and 1944 Summer Games were canceled due to World War II ,

5628-526: The process of converting dates between them became quite straightforward, through the use of conversion tables known as "hemerologia". The three most important of these calendars are the Alexandrian calendar and the Ancient Macedonian calendar ─which had two forms: the Syro-Macedonian and the 'Asian' calendars. Other reformed calendars are known from Cappadocia , Cyprus and the cities of (Roman) Syria and Palestine. Unreformed calendars continued to be used in Gaul (the Coligny calendar ), Greece, Macedon,

5712-411: The provincial calendars that were aligned to the Julian calendar. Other name changes were proposed but were never implemented. Tiberius rejected a senatorial proposal to rename September as "Tiberius" and October as "Livius", after his mother Livia. Antoninus Pius rejected a senatorial decree renaming September as "Antoninus" and November as "Faustina", after his empress . Much more lasting than

5796-451: The reform. Sosigenes may also have been the author of the astronomical almanac published by Caesar to facilitate the reform. Eventually, it was decided to establish a calendar that would be a combination between the old Roman months, the fixed length of the Egyptian calendar, and the 365 + 1 ⁄ 4 days of Greek astronomy. According to Macrobius, Caesar was assisted in this by a certain Marcus Flavius. Caesar's reform only applied to

5880-444: The regular intervals would have meant (summer) Olympic Games should have occurred in 1940 and 1944, but both were cancelled due to World War II . Nonetheless, the count of the Olympiads continued: The 1936 Games were those of the XI Olympiad, while the next Summer Games were those of 1948, which were the Games of the XIV Olympiad. The current Olympiad is the XXXIII of the modern era, which began on 1 January 2024. Note, however, that

Olympiad An olympiad ( Greek : Ὀλυμπιάς , Olympiás ) is a period of four years, particularly those associated with the ancient and modern Olympic Games . Although the ancient Olympics were established during Greece's Archaic Era , it was not until Hippias that a consistent list was established and not until Ephorus in

The Gregorian calendar has the same months and month lengths as the Julian calendar, but, in the Gregorian calendar, year numbers evenly divisible by 100 are not leap years, except that those evenly divisible by 400 remain leap years (even then, the Gregorian calendar diverges from astronomical observations by one day in 3,030 years). Although

6132-487: The start of the four seasons, which would have been impossible only 8 years earlier. A century later, when Pliny dated the winter solstice to 25 December because the sun entered the 8th degree of Capricorn on that date, this stability had become an ordinary fact of life. Although the approximation of 365 + 1 ⁄ 4 days for the tropical year had been known for a long time, ancient solar calendars had used less precise periods, resulting in gradual misalignment of

6216-422: The starting date back three years to 8 BC, and from the lunar synchronism back to 26 January (Julian). But since the corresponding Roman date in the inscription is 24 January, this must be according to the incorrect calendar which in 8 BC Augustus had ordered to be corrected by the omission of leap days. As the authors of the previous paper point out, with the correct four-year cycle being used in Egypt and

6300-653: The three-year cycle abolished in Rome, it is unlikely that Augustus would have ordered the three-year cycle to be introduced in Asia. The Julian reform did not immediately cause the names of any months to be changed. The old intercalary month was abolished and replaced with a single intercalary day at the same point (i.e., five days before the end of February). The Romans later renamed months after Julius Caesar and Augustus, renaming Quintilis as "Iulius" (July) in 44 BC and Sextilis as "Augustus" (August) in 8 BC. Quintilis

6384-510: Was abolished. The new leap day was dated as ante diem bis sextum Kalendas Martias ('the sixth doubled day before the Kalends of March'), usually abbreviated as a.d. bis VI Kal. Mart. ; hence it is called in English the bissextile day. The year in which it occurred was termed annus bissextus , in English the bissextile year. There is debate about the exact position of the bissextile day in

6468-567: Was held. The English term is still often used popularly to indicate the games themselves, a usage that is uncommon in ancient Greek (as an Olympiad is most often the time period between and including sets of games). It is also used to indicate international competitions other than physical sports . This includes international science olympiads , such as the International Geography Olympiad , International Mathematical Olympiad , International Forensics Olympiad, and

6552-467: Was intercalated between 1/1/45 and 1/1/40 (disregarding a momentary 'fiddling' in December of 41) to avoid the nundinum falling on Kal. Ian." Alexander Jones says that the correct Julian calendar was in use in Egypt in 24 BC, implying that the first day of the reform in both Egypt and Rome, 1 January 45 BC , was the Julian date 1 January if 45 BC was a leap year and 2 January if it

6636-434: Was not changed in ordinary years, and so continued to be the traditional 28 days. Thus, the ordinary (i.e., non-leap year) lengths of all of the months were set by the Julian calendar to the same values they still hold today. The Julian reform did not change the method used to account days of the month in the pre-Julian calendar , based on the Kalends, Nones and Ides, nor did it change the positions of these three dates within

6720-476: Was not. This necessitates fourteen leap days up to and including AD 8 if 45 BC was a leap year and thirteen if it was not. In 1999, a papyrus was discovered which gives the dates of astronomical phenomena in 24 BC in both the Egyptian and Roman calendars. From 30 August 26 BC (Julian) , Egypt had two calendars: the old Egyptian in which every year had 365 days and the new Alexandrian in which every fourth year had 366 days. Up to 28 August 22 BC (Julian)

6804-428: Was proclaimed publicly by edict, and the arrangement might have continued to stand had not the correction itself of the calendar led the priests to introduce a new error of their own; for they proceeded to insert the intercalary day, which represented the four quarter-days, at the beginning of each fourth year instead of at its end, although the intercalation ought to have been made at the end of each fourth year and before

6888-693: Was renamed to honour Caesar because it was the month of his birth. According to a senatus consultum quoted by Macrobius, Sextilis was renamed to honour Augustus because several of the most significant events in his rise to power, culminating in the fall of Alexandria, occurred in that month. Other months were renamed by other emperors, but apparently none of the later changes survived their deaths. In AD 37, Caligula renamed September as "Germanicus" after his father ; in AD 65, Nero renamed April as "Neroneus", May as "Claudius" and June as "Germanicus"; and in AD 84 Domitian renamed September as "Germanicus" and October as "Domitianus". Commodus

6972-619: Was the basis of the 76-year cycle devised by Callippus (a student under Eudoxus) to improve the Metonic cycle. In Persia (Iran) after the reform in the Persian calendar by introduction of the Persian Zoroastrian (i. e. Young Avestan) calendar in 503 BC and afterwards, the first day of the year (1 Farvardin= Nowruz ) slipped against the vernal equinox at the rate of approximately one day every four years. Likewise in

7056-496: Was unique in renaming all twelve months after his own adopted names (January to December): "Amazonius", "Invictus", "Felix", "Pius", "Lucius", "Aelius", "Aurelius", "Commodus", "Augustus", "Herculeus", "Romanus", and "Exsuperatorius". The emperor Tacitus is said to have ordered that September, the month of his birth and accession, be renamed after him, but the story is doubtful since he did not become emperor before November 275. Similar honorific month names were implemented in many of
