2010 in Roman Numerals
2010 is MMX, opening a new decade with three clean glyphs: two M and a single X.
How MMX is formed
M + M + X = 1000 + 1000 + 10 = 2010.
Where MMX is used
A year numeral turns up in different places from a bare number. These are the four that send people looking for MMX.
- Date tattoos and engravings. A year-only piece is just MMX, and a full date stacks the day and month above it. MMX is 3 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 2010 carries MMX 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 MMX 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 2010 is 16 years old, so MMX is the numeral for a 16th anniversary this year. Wedding and birth years are the two most common reasons to want MMX written correctly.
