What format does this tool use for Roman numeral dates?

The tool uses the DD·MM·YYYY convention with an interpunct (·) as the separator — for example, 14·II·MMXXV for February 14, 2025. This is the most common format used for tattoos and formal inscriptions.

Can the tool parse any Roman numeral date I type?

Yes. Switch to Parse mode, enter a Roman numeral date in DD·MM·YYYY or DD MM YYYY format (using either · or spaces as separators), and the tool will decode it to a standard date.

What years are supported?

The converter supports years from 1 to 3999, which is the full range expressible with standard Roman numerals. Years outside this range cannot be represented classically.

Does Roman numeral notation have a zero?

No. Classical Roman numerals have no symbol for zero. This means the Roman numeral system starts at I (1). Dates involving the year 0 are not representable.

Why does the year 2025 become MMXXV?

MM = 2000, XX = 20, V = 5. Roman numerals are built by combining values from largest to smallest, with subtractive notation for 4s and 9s (e.g. IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900).

Is this tool suitable for tattoo date formatting?

Yes. The DD·MM·YYYY format with interpuncts is the most popular Roman numeral tattoo date style. Always double-check the output against a second source before getting inked.
