Ab urbe condita
Ancient Roman calendar era
From Wikipedia, the free encyclopedia
Ab urbe condita (Latin: [ab ˈʊrbɛ ˈkɔndɪtaː]; 'from the founding of the City'), or anno urbis conditae (Latin: [ˈannoː ˈʊrbɪs ˈkɔndɪtae̯]; 'in the year since the city's founding'), abbreviated as AUC or AVC in Classical Latin inscriptions, expresses a date in years since 753 BC, the traditional founding of Rome.[1][2] It is an expression used in antiquity and by classical historians to refer to a given year in Ancient Rome. In reference to the traditional year of the foundation of Rome, the year 1 BC would be written AUC 753, whereas AD 1 would be AUC 754. The foundation of the Roman Empire in 27 BC would be AUC 727. The current year AD 2026 would be AUC 2779.

Usage of the term was more common during the Renaissance, when editors sometimes added AUC to Roman manuscripts they published, giving the false impression that the convention was commonly used in antiquity. In reality, the dominant method of identifying years in Roman times was to name the two consuls who held office that year.[3] In late antiquity, regnal years were also in use, as in Roman Egypt during the Diocletian era after AD 293, and in the Byzantine Empire from AD 537, following a decree by Justinian.
Use
Prior to the Roman state's adoption of the Varronian chronology – created by Titus Pomponius Atticus and Marcus Terentius Varro – there were many different dates posited for when the city was founded. This state of confusion required picking a canonical founding date for one to use an AUC date. The Varronian chronology, constructed from fragmentary sources and demonstrably about four years off of absolute events c. 340 BC,[4] placed the founding of the city on 21 April 753 BC. This date, likely arrived at by mechanical calculation but accepted with a variance of one year by the Augustan-era fasti Capitolini, has become the traditional date.[5]
From the time of Claudius (r. AD 41–54) onward, this calculation superseded other contemporary calculations. Celebrating the anniversary of the city became part of imperial propaganda. Claudius was the first to hold magnificent celebrations in honour of the anniversary of the city, in AD 47,[6][7] the eight hundredth year from the founding of the city.[8] Hadrian, in AD 121, and Antoninus Pius, in AD 147 and AD 148, held similar celebrations respectively.
In AD 248, Philip the Arab celebrated Rome's first millennium, together with Ludi saeculares for Rome's alleged tenth saeculum. Coins from his reign commemorate the celebrations. A coin by a contender for the imperial throne, Pacatianus, explicitly states "[y]ear one thousand and first", which is an indication that the citizens of the empire had a sense of the beginning of a new era, a Sæculum Novum.
Calendar era
The Anno Domini (AD) year numbering was developed by a monk named Dionysius Exiguus in Rome in AD 525 (AUC 1278), as a result of his work on calculating the date of Easter. Dionysius did not use the AUC convention, but instead based his calculations on the Diocletian era. This convention had been in use since AD 293, the year of the tetrarchy, as it became impractical to use regnal years of the current emperor.[9] In his Easter table, the year AD 532 (AUC 1285) was equated with the 248th regnal year of Diocletian. The table counted the years starting from the presumed birth of Christ, rather than the accession of the emperor Diocletian on 20 November AD 284 or, as stated by Dionysius: "sed magis elegimus ab incarnatione Domini nostri Jesu Christi annorum tempora praenotare" ("but rather we choose to name the times of the years from the incarnation of our Lord Jesus Christ").[10] Blackburn and Holford-Strevens review interpretations of Dionysius which place the Incarnation in 2 BC, 1 BC, or AD 1.[11]
The year AD 1 corresponds to AUC 754, based on the epoch of Varro. Thus:

Notes
- Urban Ottoman Turks identified as *Rûmî* (meaning "Romans") during the 15th, 16th, and 17th centuries; however, from the 18th century onwards, this identification fell out of use among Turks, who began to apply the term exclusively to the Greek and Christian population of the Ottoman Empire. With the abolition of the sultanate, the Turkish sultans' claim to the title of Caesars of Rome was also abolished.
