How MCMI is built
Roman numerals are written one decimal place at a time, largest first.
- Mthousands · 1M is 1,000.
- CMhundreds · 9C before M means 1,000 − 100 = 900. This saves writing DCCCC.
- Iones · 1I is 1.
1,000 + 900 + 1 = 1,901
The pair CM uses subtraction: a smaller letter before a larger one is taken away from it. Only six pairs work this way: IV, IX, XL, XC, CD and CM. More on subtraction
Mistakes to avoid
- Not MDCCCCI (7 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MCMI (4 letters) is the standard.
- There's no letter for zero. The zero is simply left out, which is why 1901 has 3 parts, not 4.
1901 for a tattoo or engraving
- Shortened to two digits ('01), it's I. Many date tattoos use this shorter form.
- MCMI has 4 letters. 178 of the 201 years from 1900 to 2100 are longer.
- 1901 was not a leap year (365 days), and 1 January 1901 was a Tuesday.
