Olbia ( Italian pronunciation: [ˈɔlbja] , locally [ˈolbja] ; Sardinian : Terranoa ; Gallurese : Tarranoa ) is a city and commune of 60,346 inhabitants (May 2018) in the Italian insular province of Sassari in northeastern Sardinia , Italy, in the historical region of Gallura . Called Olbia in the Roman age, Civita in the Middle Ages ( Judicates period) and the Terranova Pausania until the 1940s, Olbia has again been the official name of the city since the fascist period .
60-772: Although the name is of Greek origin, due to the Greek presence during the seventh century B.C. , the city of Olbia was first settled either by the Nuragics or by Phoenicians , according to the archaeological findings. It contains ruins from the Nuragic era to the Roman era, when it was an important port, and the Middle Ages, when it was the capital of the Giudicato of Gallura , one of the four independent states of Sardinia. During
120-668: A general tax from the known world by Octavian or the end of the roman conquest of the peninsula during the civil war of the Second Triumvirate . Either way the date traditionally marks the establishment of Roman rule in Spain and was used in official documents by the Suebian and Visigothic kingdoms and later in Portugal , Aragon , Valencia , Castile , and southern France . This system of calibrating years fell to disuse in
180-526: A referendum seven years later. Olbia is a tourist destination thanks to its sea and beaches and also for the large number of places of cultural interest to visit. Olbia has a Mediterranean climate ( Csa ), with mild winters, warm springs and autumns and hot summers. Olbia Calcio 1905 represents Olbia in Serie C , the third division of Italian football . Olbia hosted several legs of Aquabike World Championship (powerboating) in 2003, 2004, 2018, 2019. Olbia
240-515: Is always placed after the year number (for example: 70 BC but AD 70), which preserves syntactic order. The abbreviation "AD" is also widely used after the number of a century or millennium , as in "fourth century AD" or "second millennium AD" (although conservative usage formerly rejected such expressions). Since "BC" is the English abbreviation for Before Christ , it is sometimes incorrectly concluded that AD means After Death (i.e., after
300-452: Is generally accepted by experts there is a 27-year difference between AP and AD reference. The date of birth of Jesus of Nazareth is not stated in the gospels or in any secular text, but most scholars assume a date of birth between 6 BC and 4 BC. The historical evidence is too fragmentary to allow a definitive dating, but the date is estimated through two different approaches—one by analyzing references to known historical events mentioned in
360-518: Is one of the main connections between Sardinia and the Italian peninsula, with an airport ( Olbia – Costa Smeralda ), a passenger port (Olbia-Isola Bianca), and a railway from Olbia railway station to Porto Torres , Golfo Aranci and Cagliari . There is an expressway to Nuoro and Cagliari (SS131) and national roads to Sassari (SS199-E840), Tempio Pausania (SS127) and Palau (SS125). The internal city public transport and bus connections with
420-594: Is the year 2024 as per the Gregorian calendar, which numbers its years in the Western Christian era (the Coptic Orthodox and Ethiopian Orthodox churches have their own Christian eras). In antiquity, regnal years were counted from the accession of a monarch. This makes the chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as
480-653: The Byzantine Era . No single Anno Mundi epoch was dominant throughout the Christian world . Eusebius of Caesarea in his Chronicle used an era beginning with the birth of Abraham , dated in 2016 BC (AD 1 = 2017 Anno Abrahami). Spain and Portugal continued to date by the Spanish Era (also called Era of the Caesars ), which began counting from 38 BC, well into the Middle Ages. In 1422, Portugal became

Although anno Domini was in widespread use by the 9th century, the term "Before Christ" (or its equivalent) did not become common until much later. Bede used the expression "anno [...] ante incarnationem Dominicam" (in the year before the incarnation of the Lord) twice. "Anno ante Christi nativitatem" (in
600-671: The Carolingian Empire ultimately lies at the core of the system's prevalence. According to the Catholic Encyclopedia , popes continued to date documents according to regnal years for some time, but usage of AD gradually became more common in Catholic countries from the 11th to the 14th centuries. In 1422, Portugal became the last Western European country to switch to the system begun by Dionysius. Eastern Orthodox countries only began to adopt AD instead of
660-523: The Diocese of Tempio–Ampurias (also integrating the Diocese of Ampurias , which was in personal union with the see of Civita from 1506). It is the economic centre of this part of the island (commercial centres, food industry) and is very close to the Costa Smeralda tourist area. It was one of the administrative capitals of the province of Olbia-Tempio , operative since 2005 and canceled after

#1732764762836720-688: The Early Middle Ages , roughly between the 6th and 10th centuries. The era based on the Incarnation of Christ was introduced by Dionysius Exiguus in 525 and is in continued use with various reforms and derivations. The distinction between the Incarnation occurring with the conception or the Nativity of Jesus was not drawn until the late ninth century. The first day of the numbered year varied from place to place and depended on
780-669: The First Punic War , the Romans fought against the Carthaginians and the Sardinians near Olbia, where the general Hanno died in battle. From 1113 it was the episcopal see of the Diocese of Cività (succeeding to the Diocese of Gallura , the 1070 restoration of the Diocese of Fausania , c. 500–750), which was renamed in 1839 as Diocese of Civita–Tempio until its formal suppression in favor of (in fact merger into)
840-527: The Gregorian and Julian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord" but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase " anno Domini nostri Jesu Christi ", which translates to "in the year of our Lord Jesus Christ ". The form "BC" is specific to English , and equivalent abbreviations are used in other languages:
900-554: The Julian or Gregorian calendars , AD 1 is immediately preceded by 1 BC, with nothing in between them (there was no year zero ). There are debates as to whether a new decade, century, or millennium begins on a year ending in zero or one. For computational reasons, astronomical year numbering and the ISO 8601 standard designate years so that AD 1 = year 1, 1 BC = year 0, 2 BC = year −1, etc. In common usage, ancient dates are expressed in
960-455: The Latin form, rarely used in English, is ante Christum natum (ACN) or ante Christum (AC). This calendar era takes as its epoch the traditionally reckoned year of the conception or birth of Jesus. Years AD are counted forward since that epoch and years BC are counted backward from the epoch. There is no year zero in this scheme; thus the year AD 1 immediately follows
1020-669: The Sumerian King List and the Babylonian Canon of Kings . In East Asia, reckoning by era names chosen by ruling monarchs ceased in the 20th century except for Japan , where they are still used. For over a thousand years, ancient Assyria used a system of eponyms to identify each year. Each year at the Akitu festival (celebrating the Mesopotamian new year), one of a small group of high officials (including
1080-572: The death of Jesus ), which would mean that the approximately 33 years commonly associated with the life of Jesus would be included in neither the BC nor the AD time scales. The anno Domini dating system was devised in 525 by Dionysius Exiguus to enumerate years in his Easter table . His system was to replace the Diocletian era that had been used in older Easter tables , as he did not wish to continue
1140-529: The 3rd year of the 6th Olympiad. Because the Parilia had become associated with the founding of the city by his time, he took the specific date to have been 21 April 753 BC. This became the official chronology of the empire by at least the time of Claudius , who held Secular Games in AD 47 to celebrate the city's 800th anniversary. The 900th and 1000th anniversaries were then celebrated in 148 under Antoninus Pius and in 248 under Philip I . The AUC era
1200-477: The Common Era (BCE). Astronomical year numbering and ISO 8601 avoid words or abbreviations related to Christianity, but use the same numbers for AD years (but not for BC years in the case of astronomical years; e.g., 1 BC is year 0, 45 BC is year −44). Traditionally, English follows Latin usage by placing the "AD" abbreviation before the year number, though it is also found after the year. In contrast, "BC"
1260-669: The Early Modern Age and was replaced by today's Anno Domini . The months and years are the same as the Julian Calendar . Throughout the Roman and Byzantine periods, the Decapolis and other Hellenized cities of Syria and Palestine used the Pompeian era , counting dates from the Roman general Pompey 's conquest of the region in 63 BC. A different form of calendar was used to track longer periods of time, and for

#17327647628361320-476: The Julian calendar, but ISO 8601 uses the Gregorian calendar and astronomers may use a variety of time scales depending on the application. Thus dates using the year 0 or negative years may require further investigation before being converted to BC or AD. Calendar era A calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. For example, it
1380-702: The Nativity accounts in the Gospels of Luke and Matthew and the second by working backwards from the estimation of the start of the ministry of Jesus . The Anglo-Saxon historian Bede , who was familiar with the work of Dionysius Exiguus, used anno Domini dating in his Ecclesiastical History of the English People , which he completed in AD 731. In the History he also used the Latin phrase ante [...] incarnationis dominicae tempus anno sexagesimo ("in
1440-543: The alternative abbreviations CE and BCE (sometimes written C.E. and B.C.E.) are sometimes used in place of AD and BC. The "Common/Current Era" ("CE") terminology is often preferred by those who desire a term that does not explicitly make religious references but still uses the same epoch as the anno Domini notation. For example, Cunningham and Starr (1998) write that "B.C.E./C.E. […] do not presuppose faith in Christ and hence are more appropriate for interfaith dialog than
1500-643: The beginning of the year. Modern application of the AUC era generally ignores this, the known mistakes in Varro's own calculations, and the 752 BC epoch used by the Fasti and later Secular Games, such that AD 2024 is generally considered equivalent to AUC 2777 (2024 + 753). Another system that is less commonly found than might be thought was the use of the regnal year of the Roman emperor . At first, Augustus indicated
1560-537: The calendar year is taken as starting on 1 Tishri or on 1 Nisan (respectively the start of the Jewish civil and ecclesiastical years) the Seleucid era begins either in 311 BC (the Jewish reckoning) or in 312 BC (the Greek reckoning: October–September). An early and common practice was Roman ' consular ' dating. This involved naming both consules ordinarii who had taken up this office on 1 January (since 153 BC) of
1620-640: The conventional B.C./A.D." Upon its foundation, the Republic of China adopted the Minguo Era but used the Western calendar for international purposes. The translated term was 西 元 ( xī yuán ; 'Western Era'). Later, in 1949, the People's Republic of China adopted 公元 ( gōngyuán ; 'Common Era') for all purposes domestic and foreign. In the AD year numbering system, whether applied to
1680-629: The cycle, an indiction being a year in duration. Documents and events began to be dated by the year of the cycle (e.g., "fifth indiction", "tenth indiction") in the 4th century, and this system was used long after the tax ceased to be collected. It was used in Gaul , in Egypt until the Islamic conquest , and in the Eastern Roman Empire until its conquest in 1453. A useful chart providing all
1740-519: The dead and end of the world would occur 500 years after the birth of Jesus. The old Anno Mundi calendar theoretically commenced with the creation of the world based on information in the Old Testament . It was believed that, based on the Anno Mundi calendar, Jesus was born in the year 5500 (5500 years after the world was created) with the year 6000 of the Anno Mundi calendar marking
1800-408: The early 1st millennium BC. This is an invaluable chronological aid, because a solar eclipse was recorded as having taken place in the limmu of Bur-Sagale, governor of Guzana . Astronomers have identified this eclipse as one that took place on 15 June 763 BC , which has allowed absolute dates of 892 to 648 BC to be assigned to that sequence of eponyms. This list of absolute dates has allowed many of
1860-479: The emperor Justinian I discontinued appointing consuls. The last consul nominated was Anicius Faustus Albinus Basilius . Soon afterwards, imperial regnal dating was adopted in its place. Another method of dating was ab urbe condita (Latin for "from the founding of the city" of Rome) or anno urbis conditae (Latin for "in the year of the founding of the city"), both abbreviated AUC. Several epochs for this date were in use by Roman historians , all based on

1920-502: The end of the world. Anno Mundi 6000 (approximately AD 500) was thus equated with the end of the world but this date had already passed in the time of Dionysius. The " Historia Brittonum " attributed to Nennius written in the 9th century makes extensive use of the Anno Passionis (AP) dating system which was in common use as well as the newer AD dating system. The AP dating system took its start from 'The Year of The Passion'. It
1980-528: The equivalents can be found in Chaîne's book on chronology, and can easily be consulted online at the Internet Archive, from page 134 to page 172 . A rule for computing the indiction from an AD year number was stated by Dionysius Exiguus : add 3 and divide by 15; the remainder is the indiction, with 0 understood to be the fifteenth indiction. Thus the indiction of 2001 was 9. The beginning of
2040-583: The events of the Neo-Assyrian Period to be dated to a specific year, avoiding the chronological debates that characterize earlier periods of Mesopotamian history. Among the ancient Greek historians and scholars, a common method of indicating the passage of years was based on the Olympic Games , first held in 776 BC . The Olympic Games provided the various independent city-states with a mutually recognizable system of dates. Olympiad dating
2100-404: The incomplete surviving list of Roman consuls and the myths of the city's founding by Romulus and Remus . The chronology established by Marcus Terentius Varro in the 1st century BC intercalated several years of dictatorships , a period of anarchy, and a standardized length of reign for all of Rome's former kings to arrive at a year running from 754–753 BC, taken as equivalent to
2160-598: The inscription of calendar dates (i.e., identifying when one event occurred in relation to others). This form, known as the Long Count , is based upon the number of elapsed days since a mythological starting-point. According to the calibration between the Long Count and Western calendars accepted by the great majority of Maya researchers (known as the GMT correlation), this starting-point is equivalent to 11 August, 3114 BC in
2220-771: The king in later periods) would be chosen by lot to serve as the limmu for the year, which meant that he would preside over the Akitu festival and the year would bear his name. The earliest attested limmu eponyms are from the Assyrian trading colony at Karum Kanesh in Anatolia, dating to the very beginning of the 2nd millennium BC, and they continued in use until the end of the Neo-Assyrian Period , c. 612 BC . Assyrian scribes compiled limmu lists, including an unbroken sequence of almost 250 eponyms from
2280-579: The last Catholic country to adopt the anno Domini system. The Era of Martyrs , which numbered years from the accession of Diocletian in 284, who launched the most severe persecution of Christians , was used by the Church of Alexandria and is still officially used by the Coptic Orthodox and Coptic Catholic churches. It was also used by the Ethiopian and Eritrean churches. Another system
2340-420: The last non-imperial consul, Basilius , was appointed in 541 by Emperor Justinian I , later emperors through to Constans II (641–668) were appointed consuls on the first of January after their accession. All of these emperors, except Justinian, used imperial post-consular years for the years of their reign, along with their regnal years. Long unused, this practice was not formally abolished until Novell XCIV of
2400-711: The law code of Leo VI did so in 888. Another calculation had been developed by the Alexandrian monk Annianus around the year AD 400, placing the Annunciation on 25 March AD 9 (Julian)—eight to ten years after the date that Dionysius was to imply. Although this incarnation was popular during the early centuries of the Byzantine Empire , years numbered from it, an Era of Incarnation , were exclusively used and are still used in Ethiopia . This accounts for
2460-412: The memory of a tyrant who persecuted Christians . The last year of the old table, Diocletian Anno Martyrium 247, was immediately followed by the first year of his table, anno Domini 532. When Dionysius devised his table, Julian calendar years were identified by naming the consuls who held office that year— Dionysius himself stated that the "present year" was "the consulship of Probus Junior ", which

2520-582: The memory of the Roman Republic faded (about AD 200), when they began to use their regnal year openly. Some regions of the Roman Empire dated their calendars from the date of Roman conquest, or the establishment of Roman rule. The Spanish era , or the Era of Caesar , counted the years from 38 BC and, although the exact reasons for this are unknown, it is usually attributed to either the levy of
2580-446: The proleptic Gregorian calendar or 6 September in the Julian calendar (−3113 astronomical). A great many local systems or eras were also important, for example the year from the foundation of one particular city, the regnal year of the neighboring Persian emperor , and eventually even the year of the reigning Caliph . Most of the traditional calendar eras in use today were introduced at the time of transition from Late Antiquity to
2640-408: The relevant civil year. Sometimes one or both consuls might not be appointed until November or December of the previous year, and news of the appointment may not have reached parts of the Roman empire for several months into the current year; thus we find the occasional inscription where the year is defined as "after the consulate" of a pair of consuls. The use of consular dating ended in AD 541 when
2700-504: The seven- or eight-year discrepancy between the Gregorian and Ethiopian calendars . Byzantine chroniclers like Maximus the Confessor , George Syncellus , and Theophanes dated their years from Annianus' creation of the world. This era, called Anno Mundi , "year of the world" (abbreviated AM), by modern scholars, began its first year on 25 March 5492 BC. Later Byzantine chroniclers used Anno Mundi years from 1 September 5509 BC,

Both Dionysius and Bede regarded anno Domini as beginning at the incarnation of Jesus Christ , but "the distinction between Incarnation and Nativity was not drawn until the late 9th century, when in some places the Incarnation epoch

Other private carriers operate with lines under concession. The major hospitals in the area are: Anno Domini The terms anno Domini ( AD ) and before Christ ( BC ) are used when designating years in
2880-410: The underlying date." Bonnie J. Blackburn and Leofranc Holford-Strevens briefly present arguments for 2 BC, 1 BC, or AD 1 as the year Dionysius intended for the Nativity or incarnation . Among the sources of confusion are: It is not known how Dionysius established the year of Jesus's birth. One major theory is that Dionysius based his calculation on the Gospel of Luke , which states that Jesus
2940-407: The year 1 BC . This dating system was devised in 525 by Dionysius Exiguus but was not widely used until the 9th century. (Modern scholars believe that the actual date of birth of Jesus was about 5 BC.) Terminology that is viewed by some as being more neutral and inclusive of non-Christian people is to call this the Common Era (abbreviated as CE), with the preceding years referred to as Before
3000-470: The year before the birth of Christ) is found in 1474 in a work by a German monk. In 1627, the French Jesuit theologian Denis Pétau (Dionysius Petavius in Latin), with his work De doctrina temporum , popularized the usage ante Christum (Latin for "Before Christ") to mark years prior to AD. When the reckoning from Jesus' incarnation began replacing the previous dating systems in western Europe, various people chose different Christian feast days to begin
3060-416: The year for the indiction varied. The Seleucid era was used in much of the Middle East from the 4th century BC to the 6th century AD, and continued until the 10th century AD among Oriental Christians. The era is computed from the epoch 312 BC: in August of that year Seleucus I Nicator captured Babylon and began his reign over the Asian portions of Alexander the Great 's empire. Thus depending on whether

TRP), carefully observing the fiction that his powers came from these offices granted to him, rather than from his own person or the many legions under his control. His successors followed his practice until
3180-543: The year: Christmas, Annunciation , or Easter. Thus, depending on the time and place, the year number changed on different days in the year, which created slightly different styles in chronology: With these various styles, the same day could, in some cases, be dated in 1099, 1100 or 1101. During the first six centuries of what would come to be known as the Christian era, European countries used various systems to count years. Systems in use included consular dating , imperial regnal year dating, and Creation dating . Although
3240-588: Was "about thirty years old" shortly after "the fifteenth year of the reign of Tiberius Caesar", and hence subtracted thirty years from that date, or that Dionysius counted back 532 years from the first year of his new table. This method was probably the one used by ancient historians such as Tertullian , Eusebius or Epiphanius , all of whom agree that Jesus was born in 2 BC, probably following this statement of Jesus' age (i.e. subtracting thirty years from AD 29). Alternatively, Dionysius may have used an earlier unknown source. The Chronograph of 354 states that Jesus
3300-451: Was 525 years "since the incarnation of our Lord Jesus Christ". Thus, Dionysius implied that Jesus' incarnation occurred 525 years earlier, without stating the specific year during which his birth or conception occurred. "However, nowhere in his exposition of his table does Dionysius relate his epoch to any other dating system, whether consulate, Olympiad , year of the world , or regnal year of Augustus; much less does he explain or justify
3360-403: Was born during the consulship of Caesar and Paullus (AD 1), but the logic behind this is also unknown. It has also been speculated by Georges Declercq that Dionysius' desire to replace Diocletian years with a calendar based on the incarnation of Christ was intended to prevent people from believing the imminent end of the world . At the time, it was believed by some that the resurrection of

On the continent of Europe, anno Domini was introduced as the era of choice of the Carolingian Renaissance by the English cleric and scholar Alcuin in the late eighth century.

The modern Olympic Games (or Summer Olympic Games beginning 1896) do not continue the four year periods from ancient Greece: the 669th Olympiad would have begun in the summer of 1897, but the modern Olympics were first held in 1896. The indiction cycle was an agricultural tax cycle implemented in Roman Egypt. 15 indictions made up
3540-552: Was seldom used in the traditional Roman or early Julian calendars . Naming each year by its two consuls or by the emperor's regnal years predominated, with Hadrian 's aurei and sestertii marking the Romaea in AUC 874 ( ann dccclxxiiii nat vrb ) a notable exception. AUC dating became more common in late antiquity, appearing in Censorinus , Orosius , and others. During the early Middle Ages, some church officials like Boniface IV employed AUC and AD dating together. Historical Roman dating employed several different dates for
3600-458: Was to date from the crucifixion of Jesus , which as early as Hippolytus and Tertullian was believed to have occurred in the consulate of the Gemini (AD 29), which appears in some medieval manuscripts. Alternative names for the anno Domini era include vulgaris aerae (found 1615 in Latin), "Vulgar Era" (in English, as early as 1635), "Christian Era" (in English, in 1652), " Common Era " (in English, 1708), and "Current Era".
