Roman Numeral Date Converter
Convert a date into Roman numerals, the way it appears on monuments and clocks.
Dates in Roman numerals
Roman numerals turn up on foundation stones, monuments, book copyright lines and film credits, often rendering a whole date in the old style. Writing or reading one is fiddly, especially a four-digit year full of numerals. This converts a date into Roman numerals and back, so you can decode the date carved on a building or render a date in that classic style for a design.

Years, and the clock quirk
Years are where Roman dates get long and error-prone — a year like 1888 is a mouthful of numerals, which is exactly why decoding one by hand is a chore. There is also a charming quirk worth knowing from Roman-numeral clock faces: four is very often shown as IIII rather than the usual IV, a traditional convention on clocks for visual balance. For dates on monuments and formal designs, converting removes the guesswork of assembling or reading a long string of numerals correctly.
