How MCMXXIV is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1924 separately and joining the pieces gives MCMXXIV:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 2 | 20 | XX |
| Ones | 4 | 4 | IV |
Reading it back, left to right:
- M = 1,000 → running total 1,000
- CM = 900 (M minus C) → running total 1,900
- X = 10 → running total 1,910
- X = 10 → running total 1,920
- IV = 4 (V minus I) → running total 1,924
Why MCMXXIV has 7 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMXXIV after MCM — XXIV — spells out 24. Of the 201 years from 1900 to 2100, 54 have a longer numeral and 101 a shorter one.
The rules MCMXXIV follows
- Largest to smallest. MCMXXIV uses the symbols M, C, X, I and V (7 characters in all), and the values never increase from left to right except inside a subtractive pair.
- Subtraction. CM (900) and IV (4) are subtractive pairs: 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 MCMXXIV uses two of them.
- Repetition. XX repeats X two 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 1924
- MDCCCCXXIV — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMXXIV.
- MCMXXIIII — wrong because standard numerals never repeat a symbol four times; 4 is written IV. The correct form is MCMXXIV.
The year 1924 in Roman numerals: where it appears
- Cornerstones and public buildings. Buildings, bridges and monuments from the early 20th century often have their completion year carved as a numeral, so MCMXXIV may be cut into a date stone or lintel from 1924.
- An Olympiad year. 1924 is the year of the Games of the VIII Olympiad — Paris.
- On a calendar. 1924 was a leap year, with 366 days, and January 1 fell on a Tuesday. A full date such as July 4, 1924 is often written VII · IV · MCMXXIV.

No. MDCCCCXXIV is wrong because standard numerals never repeat a symbol four times; 900 is written CM. The standard numeral for 1924 is MCMXXIV.
