2003 in Roman Numerals
2003 is written MMIII in Roman numerals, 23 years in the past. Reading left to right, M + M + I + I + I add up to 2003, which is exactly why Roman-numeral years suit tattoos and dedications: the letters carry the date without a single Arabic digit.
How MMIII is formed
M + M + I + I + I = 1000 + 1000 + 1 + 1 + 1 = 2003.
Where MMIII is used
A year numeral turns up in different places from a bare number. These are the four that send people looking for MMIII.
- Date tattoos and engravings. A year-only piece is just MMIII, and a full date stacks the day and month above it. MMIII is 5 characters long, which matters more than people expect: it sets how wide the bottom line of a stacked date will sit.
- Copyright lines in credits. Film and television end credits have long set the copyright year in Roman numerals, so a production from 2003 carries MMIII on its end card. If you are reading a numeral off a title sequence rather than writing one, this is usually the one you have found.
- Cornerstones and dedications. Buildings, monuments and foundation stones carry their year in numerals, which is why MMIII turns up carved rather than typed. Every year between 2000 and 2099 opens with MM, so on a datestone it is the letters after MM that tell you which year you are actually looking at.
- Anniversaries. In 2026, a date from 2003 is 23 years old, so MMIII is the numeral for a 23rd anniversary this year. Wedding and birth years are the two most common reasons to want MMIII written correctly.

Why does MMIII start with MM?
MM is the numeral for 2000, and every year from 2000 to 2099 opens with it. The letters after it, III, carry the remaining 3.
Where will I see MMIII written down?
MMIII turns up on film and television copyright lines, foundation stones, memorials and date tattoos. If you are reading MMIII off a title sequence or a building, you have found the year 2003.
How do you write 2003 for a tattoo?
The correct form is MMIII. For a vertical piece the same letters are simply stacked, and for a full date the day and month sit above the year on their own lines. Keeping the spelling standard means a tattoo artist can copy it directly.
