Convert modern calendar dates to Roman numerals, Classical Roman calendar style (Kalends, Nones, Ides), and Ab Urbe Condita (AUC) dating.
In ancient Rome, days were counted backwards towards three primary monthly markers: Kalends (Kalendae) (the 1st of every month), Nones (Nonae) (the 5th or 7th), and Ides (Idus) (the 13th or 15th). The founding of Rome is traditionally dated to 753 BC (Ab Urbe Condita - AUC).
