The 2020s in Roman Numerals
Every year of the 2020s, converted: 2020 is MMXX and 2029 is MMXXIX. 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: 2020–2029
| Year | Roman numerals | Turns in 2026 | Year | Roman numerals | Turns in 2026 |
|---|---|---|---|---|---|
| 2020 | MMXX | 6 | 2021 | MMXXI | 5 |
| 2022 | MMXXII | 4 | 2023 | MMXXIII | 3 |
| 2024 | MMXXIV | 2 | 2025 | MMXXV | 1 |
| 2026 | MMXXVI | 0 | 2027 | MMXXVII | -1 |
| 2028 | MMXXVIII | -2 | 2029 | MMXXIX | -3 |
“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 2020s 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 2024 ends in IV and 2029 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.
