Question: how is a date written in roman numerals?
Answer: Date in Roman numerals for large numbers are nowadays seen mainly in the form of year numbers, as in these historical examples: 1776 (M+DCC+LXX+VI) = MDCCLXXVI (the date written on the book held by the Statue of Liberty). 1954 (M+CM+L+IV) = MCMLIV (as in the trailer for the movie The Last Time I Saw Paris).
