Roman Numeral Date Converter

Worked out on your device, so it follows your time zone and changes at midnight.

In the United States dates are written month, day, year, while most other countries put the day first (source: iso.mit.edu). July 4, 2026 is VII.IV.MMXXVI in the US order and IV.VII.MMXXVI day first. The converter starts with the US order; switch it if the reader is in the UK, Europe or Latin America.

Year, month, day is the ISO 8601 order (source: blog.ansi.org): MMXXVI-VII-IV. It cannot be confused, but few people read a date that way at a glance.

Dots are the most common choice (XI.XI.MMXXVI). A middle dot (XI·XI·MMXXVI) or spaces read well when engraved, because they leave a gap without a mark that can blur. Slashes and hyphens suit plain text. Whatever you pick, use the same one between every part.

Some documents keep the day and year in digits and write only the month in Roman numerals, so the two cannot be mixed up (source: en.wikipedia.org). Choose the style "Roman month only" to get, for example, 11.XI.2026: November is XI, the rest stays in digits.

There is no zero in Roman numerals, so there is no leading zero either: the 5th is V, never 0V. The same goes for a two-digit year: 2000 would be 00, so the converter asks for the full year. Years from 1 to 3999 work; for larger numbers use the converter with the bar.

Enter a date of birth and the result also shows the age it reaches today, in digits and in Roman numerals. December 25, 1990, for example, is XII.XXV.MCMXC, and the year alone is MCMXC. The year converter explains a single year in more detail.

Check each part on its own: day, month and year. The usual slips are swapping IV and VI, writing four I's in a row, and typing the digit 1 instead of the letter I. Paste each part into the validator, or press "Open in the Tattoo Generator" to see the same date in different fonts and layouts.
