Frequently Asked Questions
Why is the year range limited to 1-3999?
Roman numerals don't have a standard representation for numbers 4000 and above. 3999 (MMMCMXCIX) is the largest number representable with standard Roman numerals.
How do I represent the year 4000 and beyond?
There are various non-standard extensions, such as using a vinculum (overline) to multiply by 1000, but these are not universally accepted and best avoided for clarity.
Were there any other ways of counting the years?
Yes, one famous example is Ab Urbe Condita (AUC). This counts from the founding of Rome, which is equivalent to 753 BC.
How do I enter a Roman numeral date?
Use the format DD/MM/YYYY, where DD is the day, MM is the month, and YYYY is the year, all in Roman numerals. For example, V/I/MMXXIV is January 5, 2024.
Does this converter handle BC/BCE dates?
No, this converter only handles years 1-3999 AD/CE. Roman numerals were not commonly used for years before the Common Era.
