Origin of AUC

From Latin AUC, (anno) ab urbe condita (“from the founding of the city”) or anno urbis conditae (“in the year of the city's having been founded”), both in reference to Rome's legendary establishment by Romulus. The era was not in common use by the Romans, who preferred dating by the years' consuls, but Roman historians give several dates for this era. The one most commonly used in the present day is Varro's, which dates from the third year of the sixth Olympiad (753 bc).
