How MCMLXXXI 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.
- LXXXtens · 8L (50) plus XXX (30) makes 80.
- Iones · 1I is 1.
1,000 + 900 + 80 + 1 = 1,981
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 MDCCCCLXXXI (11 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MCMLXXXI (8 letters) is the standard.
1981 for a tattoo or engraving
- Shortened to two digits ('81), it's LXXXI. Many date tattoos use this shorter form.
- MCMLXXXI has 8 letters. 22 of the 201 years from 1900 to 2100 are longer.
- 1981 was not a leap year (365 days), and 1 January 1981 was a Thursday.
