About this tool

This converter turns a calendar date into Roman numerals — a popular choice for tattoos, jewelry engravings, wedding invitations, and anniversary keepsakes. It runs entirely in your browser, so the date you enter is never uploaded.

Each part of the date is converted separately using the standard subtractive Roman numeral algorithm, working down through the values M, CM, D, CD, C, XC, L, XL, X, IX, V, IV and I. For example, 14 becomes XIV, 3 becomes III, and 2024 becomes MMXXIV. You choose the order — day·month·year, month·day·year, or year·month·day — and the separator (interpunct ·, slash /, dash –, or dot .), and the three numerals are joined accordingly. So 14 March 2024 in day-month-year order with an interpunct reads XIV·III·MMXXIV.

Set the date, pick your order and separator, and the full Roman date plus each individual component appears instantly. Use the Copy button to grab the exact text for a design or tattoo reference.

Frequently asked questions

How are the numerals formed?
Day, month, and year are each converted independently with the standard subtractive method, which uses pairs like CM (900), CD (400), XC (90), XL (40), IX (9) and IV (4) so numerals are never repeated more than three times in a row.
Which order and separator should I use for a tattoo?
It is a style choice. Day·month·year with an interpunct (·) is the most common look for tattoos, but the tool lets you preview month-first and year-first orders and slash, dash, or dot separators too.
There is no Roman symbol for zero — how are single-digit days shown?
Romans had no leading zeros, so the 3rd of a month is simply III, not 0III. Each number is written in its shortest standard form.
Is my date kept private?
Yes. The conversion happens locally in your browser with no network calls, so nothing about your date is stored or sent anywhere.
