📖 How It Works

Roman numerals are the number system used by ancient Rome, and they still appear all around us today. The system uses seven basic symbols: I (1), V (5), X (10), L (50), C (100), D (500), and M (1000). Numbers are written by combining these symbols from largest to smallest and adding their values, so VI is 5 + 1 = 6 and XVII is 10 + 5 + 1 + 1 = 17.

For numbers like 4 and 9, the Romans used subtractive notation: a smaller symbol placed before a larger one is subtracted instead of added. That is why 4 is written IV (5 − 1) rather than IIII, and 9 is written IX (10 − 1). The same rule gives us XL (40), XC (90), CD (400), and CM (900).

This calculator works in three simple steps. First, it works out your exact age in full years from your birth date. Next, it converts your age, birth year, and birth month into Roman numerals using the same rules the Romans used. Finally, it presents everything side by side so you can see your age in both standard and Roman form at a glance.
