How MCMLXXXVIII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1988 separately and joining the pieces gives MCMLXXXVIII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 8 | 80 | LXXX |
| Ones | 8 | 8 | VIII |
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
- V = 5 → running total 1,985
- I = 1 → running total 1,986
- I = 1 → running total 1,987
- I = 1 → running total 1,988
Why MCMLXXXVIII has 11 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMLXXXVIII after MCM — LXXXVIII — spells out 88. With 11 letters, MCMLXXXVIII is the longest numeral of any year from 1900 to 2100.
The rules MCMLXXXVIII follows
- Largest to smallest. MCMLXXXVIII uses the symbols M, C, L, X, V and I (11 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 MCMLXXXVIII 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 1988
- MDCCCCLXXXVIII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMLXXXVIII.
The year 1988 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 1988 production might end with “Copyright MCMLXXXVIII.”
- An Olympiad year. 1988 is the year of the Games of the XXIV Olympiad — Seoul.
- Championship numbering. The pro football championship played in early 1988 was game XXII (22), since the series began with game I in January 1967.
- On a calendar. 1988 was a leap year, with 366 days, and January 1 fell on a Friday. A full date such as July 4, 1988 is often written VII · IV · MCMLXXXVIII.
