How it works
Date order survives the numeral change
Converting a date to Roman numerals changes its notation, not its day-month order. IV/V/MMXXVI can be ambiguous without an order label. Confirm the selected format before using the result on an invitation, engraving or permanent design.
Converting a number or a calendar date
Roman numerals use symbol combinations rather than ordinary positional decimal digits. Choose number conversion or date conversion depending on the input. A converted date keeps the selected date fields but changes their written representation. Check the supported value range and notation rules before using an output in a design, because historical conventions can differ from a modern standardized conversion.
Roman numerals: formula and assumptions
Use standard subtractive notation: IV, IX, XL, XC, CD, CM.
Roman numerals have no standard zero or negative representation in this mode.
Date in Roman numerals: formula and assumptions
Convert each validated date component using standard Roman notation.
Years are limited to 1–3,999 in standard notation.
Worked example
Using the Roman numerals example:
- Integer or Roman numeral

Common questions
Can this mode represent zero or negative numbers?
No. Its standard Roman notation covers integers from 1 to 3,999 without a zero or negative representation.
Why is 4 written IV rather than IIII here?
This converter uses standard subtractive pairs, including IV, IX, XL, XC, CD and CM.
