2000 in Roman Numerals
2000 is MM, the cleanest year in centuries. Just two M glyphs, nothing else. The millennium reset the modern date to two simple thousands.
How MM is formed
M + M = 1000 + 1000 = 2000.
Where MM is used
A year numeral turns up in different places from a bare number. These are the four that send people looking for MM.
- Date tattoos and engravings. A year-only piece is just MM, and a full date stacks the day and month above it. MM is 2 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 2000 carries MM 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 MM 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 2000 is 26 years old, so MM is the numeral for a 26th anniversary this year. Wedding and birth years are the two most common reasons to want MM written correctly.

Why is 2000 just MM?
