How MCMXVII 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.
- Xtens · 1X is 10.
- VIIones · 7V (5) plus II (2) makes 7.
1,000 + 900 + 10 + 7 = 1,917
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 MDCCCCXVII (10 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MCMXVII (7 letters) is the standard.
1917 for a tattoo or engraving
- Shortened to two digits ('17), it's XVII. Many date tattoos use this shorter form.
- MCMXVII has 7 letters. 54 of the 201 years from 1900 to 2100 are longer.
- 1917 was not a leap year (365 days), and 1 January 1917 was a Monday.
