How MCMLXXXIII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1983 separately and joining the pieces gives MCMLXXXIII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 8 | 80 | LXXX |
| Ones | 3 | 3 | III |
Reading it back, left to right:
- M = 1,000 → running total 1,000
- CM = 900 (M minus C) → running total 1,900
- L = 50 → running total 1,950
- X = 10 → running total 1,960
- X = 10 → running total 1,970
- X = 10 → running total 1,980
- I = 1 → running total 1,981
- I = 1 → running total 1,982
- I = 1 → running total 1,983
Why MCMLXXXIII has 10 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMLXXXIII after MCM — LXXXIII — spells out 83. Of the 201 years from 1900 to 2100, 1 have a longer numeral and 195 a shorter one.
The rules MCMLXXXIII follows
- Largest to smallest. MCMLXXXIII uses the symbols M, C, L, X and I (10 characters in all), and the values never increase from left to right except inside a subtractive pair.
- Subtraction. CM (900) is a subtractive pair: a smaller symbol in front of a larger one is taken away from it. Only six pairs are allowed — IV, IX, XL, XC, CD and CM — and MCMLXXXIII uses one of them.
- Repetition. XXX repeats X three times and III repeats I three times. I, X, C and M may repeat up to three times in a row; V, L and D never repeat.
Common mistakes when writing 1983
- MDCCCCLXXXIII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMLXXXIII.
The year 1983 in Roman numerals: where it appears
- Film and TV credits. Copyright lines at the end of films and TV programs of the period commonly gave the year in numerals — a 1983 production might end with “Copyright MCMLXXXIII.”
- Championship numbering. The pro football championship played in early 1983 was game XVII (17), since the series began with game I in January 1967.
- On a calendar. 1983 was not a leap year (365 days), and January 1 fell on a Saturday. A full date such as July 4, 1983 is often written VII · IV · MCMLXXXIII.
