How MCMLXIV 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.
- LXtens · 6L (50) plus X (10) makes 60.
- IVones · 4I before V means 5 − 1 = 4. This saves writing IIII.
1,000 + 900 + 60 + 4 = 1,964
The pairs CM and IV use 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 MDCCCCLXIIII (12 letters). That adds everything up without subtraction. The Romans sometimes wrote numbers this way, and clocks still show 4 as IIII, but today MCMLXIV (7 letters) is the standard.
1964 for a tattoo or engraving
- Shortened to two digits ('64), it's LXIV. Many date tattoos use this shorter form.
- MCMLXIV has 7 letters. 54 of the 201 years from 1900 to 2100 are longer.
- 1964 was a leap year, with 366 days, and 1 January 1964 was a Wednesday.
