About this tool
Convert any calendar date into Roman numerals (day.month.year format, e.g. July 4, 2024 → IV.VII.MMXXIV) or decode a Roman numeral date back into a regular calendar date — a popular novelty format for tattoos, engravings, and anniversary gifts.
Frequently asked questions
- What format is used for the date?
- Day.Month.Year, each part converted to Roman numerals and separated by periods — a common convention for this kind of date display.
- Can Roman numerals represent zero or negative years?
- No — classical Roman numerals have no representation for zero, so only positive year values (1 and above) are supported.
- What's the largest year this supports?
- Up to 3999 (MMMCMXCIX), the traditional practical limit of standard Roman numeral notation without special extended symbols.
