How MCMXXVIII is built
Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 1928 separately and joining the pieces gives MCMXXVIII:
| Place | Digit | Value | Numeral |
|---|---|---|---|
| Thousands | 1 | 1,000 | M |
| Hundreds | 9 | 900 | CM |
| Tens | 2 | 20 | XX |
| 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
- X = 10 → running total 1,910
- X = 10 → running total 1,920
- V = 5 → running total 1,925
- I = 1 → running total 1,926
- I = 1 → running total 1,927
- I = 1 → running total 1,928
Why MCMXXVIII has 9 letters
Every year from 1900 to 1999 begins with MCM (1,900); the rest of MCMXXVIII after MCM — XXVIII — spells out 28. Of the 201 years from 1900 to 2100, 6 have a longer numeral and 179 a shorter one.
The rules MCMXXVIII follows
- Largest to smallest. MCMXXVIII uses the symbols M, C, X, V and I (9 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 MCMXXVIII uses one of them.
- Repetition. XX repeats X two 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 1928
- MDCCCCXXVIII — wrong because standard numerals never repeat a symbol four times; 900 is written CM. The correct form is MCMXXVIII.
The year 1928 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 MCMXXVIII may be cut into a date stone or lintel from 1928.
- An Olympiad year. 1928 is the year of the Games of the IX Olympiad — Amsterdam.
- On a calendar. 1928 was a leap year, with 366 days, and January 1 fell on a Sunday. A full date such as July 4, 1928 is often written VII · IV · MCMXXVIII.
