Frequently asked questions
How is a date written in Roman numerals?
Each part of the date is converted on its own. The day, month and year become separate Roman numerals joined by a separator, for example XI . VI . MMXXVI for 11 June 2026.
Which order should I use for a tattoo?
Day-month-year is the most common style worldwide, while month-day-year is popular in the United States. Both are valid, so pick the one you prefer.
Why is there no zero in Roman numerals?
The Roman system has no symbol for zero, so single-digit days and months are written normally. The 6th becomes VI and the 9th becomes IX.
What is the largest year this supports?
Standard Roman numerals reach 3999 (MMMCMXCIX). Years from 1 to 3999 are supported, which covers every realistic date.
Can it convert a Roman numeral back to a number?
Yes. The engine includes a parser that reads a Roman numeral and returns its value, and it rejects non-standard forms like IIII.
