What is January 23 2007 in roman numerals?

Answer 1

Using our system of counting the days of the months it would be XXIII January MMVII. However, the Romans would have said/written this differently. Their system of counting the days of the month was different.

The Roman months had three special days, the Kalends, Nones and Ides. The Kalends were the first day of the month. The Nones, fell on the 5th of months with 29 days and the 7th of months with 31 days (March, May, July, and October). It is thought that originally this was the day of the half moon. The Idesfell on the 13th of months with 29 days and the 15th of months with 31 days. It is thought that originally it was the day of the full moon.

The Romans counted the days backwards from the Kalends, Nones, or Ides days, depending on which one was nearer. The count included the said days. Therefore 23rd January would be:

Ante Diem IX Kalendas Februarias Anno MMVII, which translates as the 9th day before the Kalends of February of the year 2007. It would have been the 9th day because our current month of January has 31 days, unlike the January of the Romans which had 29 days.

This could be abbreviated a: a. d. IX Kal. Feb. a. MMVII
