1938 in Roman Numerals
1938 is MCMXXXVIII in Roman numerals. The numeral uses the subtractive rule, a smaller glyph placed before a larger one, which keeps MCMXXXVIII shorter than simply repeating symbols would.
How MCMXXXVIII is formed
M + CM + X + X + X + V + I + I + I = 1000 + 900 + 10 + 10 + 10 + 5 + 1 + 1 + 1 = 1938.
Where MCMXXXVIII is used
A year numeral turns up in different places from a bare number. These are the four that send people looking for MCMXXXVIII.
- Date tattoos and engravings. A year-only piece is just MCMXXXVIII, and a full date stacks the day and month above it. MCMXXXVIII is 10 characters long, which matters more than people expect: it sets how wide the bottom line of a stacked date will sit.
- Copyright lines in credits. Film and television end credits have long set the copyright year in Roman numerals, so a production from 1938 carries MCMXXXVIII on its end card. If you are reading a numeral off a title sequence rather than writing one, this is usually the one you have found.
- Cornerstones and dedications. Buildings, monuments and foundation stones carry their year in numerals, which is why MCMXXXVIII turns up carved rather than typed. Every year between 1900 and 1999 opens with MCM, so on a datestone it is the letters after MCM that tell you which year you are actually looking at.
- Anniversaries. In 2026, a date from 1938 is 88 years old, so MCMXXXVIII is the numeral for a 88th anniversary this year. Wedding and birth years are the two most common reasons to want MCMXXXVIII written correctly.
