About this tool
The year 2024 written in Roman numerals is MMXXIV. This page opens the converter with 2024 already entered, so the result and its construction are visible immediately: MM for 2000, XX for 20 and IV for 4.
The only subtlety in MMXXIV is the ending: 4 is written IV — one before five — using the subtractive rule, never IIII. That rule is what the converter's validator enforces in the other direction: paste MMXXIIII and it will be rejected as malformed, while MMXXIV decodes cleanly back to 2024.
Tattoo artists, engravers and designers use exactly this notation for birth years and anniversaries. Change the number in the field to check any other date — the numeral, the breakdown and the validation all update as you type, entirely in your browser.
Example. 1994 converts to MCMXCIV, and parsing MCMXCIV returns 1994.
Limit. Only the integers 1 through 3999 are accepted, and non-canonical forms such as IIII fail the strict pattern.
