How MMXLIII is built

Roman numerals are written one decimal place at a time, from the largest place to the smallest. Converting each digit of 2043 separately and joining the pieces gives MMXLIII:

PlaceDigitValueNumeral
Thousands22,000MM
Hundreds00— (zero has no symbol)
Tens440XL
Ones33III

Reading it back, left to right:

  • M = 1,000 → running total 1,000
  • M = 1,000 → running total 2,000
  • XL = 40 (L minus X) → running total 2,040
  • I = 1 → running total 2,041
  • I = 1 → running total 2,042
  • I = 1 → running total 2,043

Why MMXLIII has 7 letters

Every year from 2000 to 2099 begins with MM (2,000); the rest of MMXLIII after MM — XLIII — spells out 43. Of the 201 years from 1900 to 2100, 54 have a longer numeral and 101 a shorter one.

The rules MMXLIII follows

  • Largest to smallest. MMXLIII uses the symbols M, X, L and I (7 characters in all), and the values never increase from left to right except inside a subtractive pair.
  • Subtraction. XL (40) 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 MMXLIII uses one of them.
  • Repetition. MM repeats M 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 2043

  • MMXXXXIII — wrong because standard numerals never repeat a symbol four times; 40 is written XL. The correct form is MMXLIII.

The year 2043 in Roman numerals: where it appears

  • Planning ahead. If you are designing a date stone, a time-capsule plaque or an anniversary engraving for 2043, MMXLIII is the standard form to carve or engrave.
  • Championship numbering. The pro football championship due in early 2043 will be game LXXVII (77), since the series began with game I in January 1967.
  • On a calendar. 2043 is not a leap year (365 days), and January 1 falls on a Thursday. A full date such as July 4, 2043 is often written VII · IV · MMXLIII.
