About this tool

Roman numeral dates are a classic choice for wedding rings, tattoos, monument engravings, and anniversary gifts — a way of writing a meaningful date that feels timeless. This tool splits whatever you type on slashes, dashes, dots or spaces, converts every purely numeric segment (month, day, and year) into its Roman numeral equivalent using the standard subtractive notation, and leaves any non-numeric segment untouched. Enter a date like 09/18/2026 and get back the month, day, and year each rendered in numerals, separated for easy reading.

What date formats can I enter?

Any format that separates the month, day and year with a slash, dash, dot or space works — for example 09/18/2026, 09-18-2026, or 09.18.2026 all convert the same way.

How does it handle the year 2026, which is a large number?

Roman numerals can represent any positive whole number using repeated combinations of the standard symbols (M, D, C, L, X, V, I), so a four-digit year like 2026 converts correctly to MMXXVI with no upper limit issue for realistic dates.

Can I convert just a single number instead of a full date?

Yes — type any single number on its own and it converts to its Roman numeral form the same way each date segment does.

Dates and numbers in Roman numerals

Type a date or a run of numbers and each number is converted to Roman numerals, separated by dots. Write the date in the order you want it to appear, since the tool simply converts each number as it comes.

The classic use is a tattoo, an engraving or an anniversary gift where the date looks better in numerals. It also helps with film credits, clock faces, book chapters and tidy headings.

Roman numerals have no zero, so a 0 comes out as a dash, and numbers from 4000 up are just a long row of M's. Check anything unusual before you commit it to ink.

A quick example

Before
9/18/2026
After
IX · XVIII · MMXXVI

Good to know

For a date in day-month-year order, type it that way: 18/09/2026 gives XVIII · IX · MMXXVI. Anything that isn't a number, like a month name, is left as it is.
