Convert a date to Roman numerals

How date conversion works

The day, month, and year are three separate numbers. For 19 September 2026 in day-month-year order, the components are 19 = XIX, 9 = IX, and 2026 = MMXXVI. The formatted result is XIX·IX·MMXXVI.

This is a modern decorative format, not a claim about how every ancient Roman inscription recorded dates. If a date will be engraved or tattooed, confirm the source date and regional order independently before committing.

Frequently asked questions

Should a zero be included for a single-digit month?

No. Standard Roman numerals have no zero, so September is IX, not 09 in Roman form.

Can this convert years after 3999?

No. The plain-text converter uses the common 1–3999 system. Larger years need special overline notation.

Can I decode the individual parts?

Yes. Paste each part into the Roman numeral converter.
