How MMXXI is built
Roman numerals are written one decimal place at a time, largest first.
- MMthousands · 2MM is 2 × M (1,000), written out 2 times.
- XXtens · 2X written 2 times: 2 × 10 = 20.
- Iones · 1I is 1.
2,000 + 20 + 1 = 2,021
No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
Mistakes to avoid
- There's no letter for zero. The zero is simply left out, which is why 2021 has 3 parts, not 4.
2021 for a tattoo or engraving
- Shortened to two digits ('21), it's XXI. Many date tattoos use this shorter form.
- MMXXI has 5 letters. 146 of the 201 years from 1900 to 2100 are longer.
- 2021 was not a leap year (365 days), and 1 January 2021 was a Friday.
