Roman Numeral Converter Date

Wedding dates, birthdays and anniversaries look timeless in Roman numerals — on a tattoo, a ring engraving or an invitation. Enter a date and this converter writes it in Roman numerals in the order you choose, shows exactly how each part is built so you can double-check it, and prints a large, clean version. It also converts Roman numerals back into numbers.

How Roman numerals work

Numerals are written from largest to smallest and added up: VIII = 5 + 1 + 1 + 1 = 8. When a smaller symbol comes before a larger one, it is subtracted — but only in six standard pairs: IV (4), IX (9), XL (40), XC (90), CD (400) and CM (900). A symbol is never repeated more than three times in a row, so 4 is IV rather than IIII (although IIII appears on some clock faces).

Writing a year

Break the year into thousands, hundreds, tens and ones, and convert each part. 1994 = 1000 + 900 + 90 + 4 = M + CM + XC + IV = MCMXCIV. 2026 = 2000 + 20 + 6 = MM + XX + VI = MMXXVI. 1987 = M + CM + LXXX + VII = MCMLXXXVII. The tool shows this breakdown for every part of your date, so you can check it digit by digit before anything is inked or engraved.

Common dates in Roman numerals

Choosing the order and separator

• Use the order people around you read dates in: month first in the US, day first in most other countries.
• Year-first order (YYYY.MM.DD) avoids ambiguity completely.
• Dots are the most common separator for tattoos; middle dots and bars look elegant in print.
• Two-digit years (XXVI for 2026) are shorter, but make the date less clear.
• Write down the plain date beside the numerals when you brief an artist or engraver.

Before you get a Roman numeral tattoo

1. Convert the date here and check each part against the breakdown.
2. Decide the order — and remember others may read it differently.
3. Print the date large and check it at the actual size you want.
4. Ask the artist to confirm the spelling from your printout, not from memory.
5. Look at the stencil carefully before the needle starts: a missing I changes the date.

Roman numerals back to numbers

Type a Roman numeral in the second box to convert it to a number. Read left to right, adding each value unless it is smaller than the next symbol, in which case you subtract it: MCMXCIV = 1000 + (1000 − 100) + (100 − 10) + (5 − 1) = 1994. The tool also warns you if a numeral is written in a non-standard way, such as IIII or IC, and shows the standard form.

Roman numerals on clocks, films and events

Roman numerals are still used where a formal or classic look matters: clock faces, book chapters, monarchs and popes (Elizabeth II), film copyright dates, and major sporting events. Clock faces are a famous exception to the usual rules: many use IIII for four instead of IV, a tradition often explained as giving the dial better visual balance opposite VIII.

Common mistakes to avoid

Mistakes like these are easy to make when converting by hand and impossible to fix once they are tattooed or engraved, which is why the converter shows a breakdown you can check.

Reading dates on buildings and documents

Foundation stones, old books and film credits often give a year in Roman numerals. Split the numeral into thousands, hundreds, tens and ones as you read: MDCCLXXVI is M (1000) + DCC (700) + LXX (70) + VI (6) = 1776.

Engraving and invitations

For ring engravings, space is tight: a US-order date such as VI.XIV.MMXXVI is 13 characters, while the two-digit year form VI.XIV.XXVI is 11. Ask your jeweller how many characters fit. On wedding invitations, Roman numerals look best set in a classic serif typeface with generous letter spacing, and many couples add the plain date elsewhere on the card for clarity.

Limits

Standard Roman numerals have no symbol for zero and are normally used for numbers from 1 to 3,999. Larger numbers were written with a bar over a numeral to multiply it by 1,000, but those forms are rarely used today.

Printable pack

The optional pack includes a Roman numerals chart from 1 to 100, a years chart from 1900 to 2050, days 1–31 and months 1–12 reference cards, a practice worksheet with answers and a large-print date template for tattoo and engraving planning. The converter above is free.
