The 2000s in Roman Numerals
Every year of the 2000s, converted: 2000 is MM and 2009 is MMIX. Birth years from this decade are among the most converted numbers there are — for tattoos, pendants, anniversary pieces and the copyright line at the end of a film.
Year by year: 2000–2009
| Year | Roman numerals | Turns in 2026 | Year | Roman numerals | Turns in 2026 |
|---|---|---|---|---|---|
| 2000 | MM | 26 | 2001 | MMI | 25 |
| 2002 | MMII | 24 | 2003 | MMIII | 23 |
| 2004 | MMIV | 22 | 2005 | MMV | 21 |
| 2006 | MMVI | 20 | 2007 | MMVII | 19 |
| 2008 | MMVIII | 18 | 2009 | MMIX | 17 |
“Turns in 2026” is the age someone born in that year reaches on their birthday in 2026 — the number that matters for milestone pieces: a 40th in 2026 means a 1986 birth year, MCMLXXXVI.
Reading a 2000s year
Every year in this decade opens with MM — the 2000s. What changes from year to year is the tail: the tens and units follow exactly the pattern of the 1–100 chart, so 2004 ends in IV and 2009 in IX. If the year is part of a full date — a birth date on a pendant, a wedding date inside a ring — use the date converter so the day and month are converted with it, in the right order.
