Ab urbe condita Classical orthography: AUC is a year-numbering ab urbe condita dating used by some ancient Roman historians to identify particular Roman years.

The dominant method of identifying Roman years in Roman times ab urbe condita dating to name the two consuls who held office that year. The regnal year of the emperor was also used to identify years, especially in the Byzantine Empire afterwhen Justinian required its use. The traditional date for the founding of Rome of 21 April BC, was initiated by 1st century BC scholar Marcus Terentius Varro. Varro may have used the consular ab urbe condita dating with its mistakes ab urbe condita dating called the year of the first consuls " ab urbe condita ", accepting the year interval from Dionysius of Halicarnassus for the kings after the foundation of Rome.

In his Easter table the year was equated with the regnal year of Emperor Diocletian.

The table counted the years starting from the presumed birth of Christ, rather than the accession of the emperor Diocletian on 20 Novemberor as stated by Dionysius: This however resulted in that year not corresponding with the lifetimes of historical figures reputed to be alive, or otherwise mentioned in connection with the Christian incarnation, e.
