Roman numerals to a date or number

Each 1 among the letters was read as the letter I.

These three numbers are not a real date in any common order.

  • (July 4, 1776): VII.IV.MDCCLXXVI, month first.
  • (July 20, 1969): VII.XX.MCMLXIX, or XX.VII.MCMLXIX day first.
  • (November 9, 1989): XI.IX.MCMLXXXIX, a date whose month-first and day-first forms both look like real dates.

What is today's date in Roman numerals?

Today, November 11, 2026, is XI.XI.MMXXVI in the US order (month, day, year) and XI.XI.MMXXVI in the day-first order used in the UK and Europe. Year first, it is MMXXVI.XI.XI.

How to write a date in Roman numerals

Convert the month, the day and the year separately, then put them in the order you want with a mark between them. July 4, 1776 is month 7 (VII), day 4 (IV) and year 1776 (MDCCLXXVI), so it is VII.IV.MDCCLXXVI in the US order and IV.VII.MDCCLXXVI in the day-first order used in the UK and most of Europe.

Roman numerals have no zero, so there are no leading zeros either: the 7th month is VII, never 07 or 0VII. Dots are a common mark between the parts. Middle dots (VII·IV·MDCCLXXVI) echo the dots Roman inscriptions used between words, and dashes, slashes or plain spaces work too.

Getting a date tattoo right

A Roman numeral date does not say which order it is in. XI.IX.MCMLXXXIX is November 9 to an American and 11 September to a British reader, so decide the order before you go to the artist, and keep it the same as the way you write dates.

Check the year letter by letter against the converter: the common mistakes are writing 4 as IIII, 9 as VIIII, or 90 as LXXXX (1990 is MCMXC, not MCMLXXXX). A year in the 1900s starts MCM and one in the 2000s starts MM, so 1988 is MCMLXXXVIII (11 letters) and 2008 is MMVIII. The longest year so far is 1888, MDCCCLXXXVIII, at 13 letters.

Recent years in Roman numerals

An I can look like a 1 in print, so a year that seems to read MMXX11 is really MMXXII (2022), and MMXV1 is MMXVI (2016). The converter reads a 1 among the letters as an I.

2000 = MM 2001 = MMI 2002 = MMII 2003 = MMIII 2004 = MMIV 2005 = MMV 2006 = MMVI 2007 = MMVII 2008 = MMVIII 2009 = MMIX 2010 = MMX 2011 = MMXI 2012 = MMXII 2013 = MMXIII 2014 = MMXIV 2015 = MMXV 2016 = MMXVI 2017 = MMXVII 2018 = MMXVIII 2019 = MMXIX 2020 = MMXX 2021 = MMXXI 2022 = MMXXII 2023 = MMXXIII 2024 = MMXXIV 2025 = MMXXV 2026 = MMXXVI 2027 = MMXXVII 2028 = MMXXVIII 2029 = MMXXIX 2030 = MMXXX

Years from 1900 to 1999 in Roman numerals

Every year of the 1900s starts with MCM, which is 1900. The last two digits follow, so 1985 is MCM + LXXX + V: MCMLXXXV.

1900 = MCM 1901 = MCMI 1902 = MCMII 1903 = MCMIII 1904 = MCMIV 1905 = MCMV 1906 = MCMVI 1907 = MCMVII 1908 = MCMVIII 1909 = MCMIX 1910 = MCMX 1911 = MCMXI 1912 = MCMXII 1913 = MCMXIII 1914 = MCMXIV 1915 = MCMXV 1916 = MCMXVI 1917 = MCMXVII 1918 = MCMXVIII 1919 = MCMXIX 1920 = MCMXX 1921 = MCMXXI 1922 = MCMXXII 1923 = MCMXXIII 1924 = MCMXXIV 1925 = MCMXXV 1926 = MCMXXVI 1927 = MCMXXVII 1928 = MCMXXVIII 1929 = MCMXXIX 1930 = MCMXXX 1931 = MCMXXXI 1932 = MCMXXXII 1933 = MCMXXXIII 1934 = MCMXXXIV 1935 = MCMXXXV 1936 = MCMXXXVI 1937 = MCMXXXVII 1938 = MCMXXXVIII 1939 = MCMXXXIX 1940 = MCMXL 1941 = MCMXLI 1942 = MCMXLII 1943 = MCMXLIII 1944 = MCMXLIV 1945 = MCMXLV 1946 = MCMXLVI 1947 = MCMXLVII 1948 = MCMXLVIII 1949 = MCMXLIX 1950 = MCML 1951 = MCMLI 1952 = MCMLII 1953 = MCMLIII 1954 = MCMLIV 1955 = MCMLV 1956 = MCMLVI 1957 = MCMLVII 1958 = MCMLVIII 1959 = MCMLIX 1960 = MCMLX 1961 = MCMLXI 1962 = MCMLXII 1963 = MCMLXIII 1964 = MCMLXIV 1965 = MCMLXV 1966 = MCMLXVI 1967 = MCMLXVII 1968 = MCMLXVIII 1969 = MCMLXIX 1970 = MCMLXX 1971 = MCMLXXI 1972 = MCMLXXII 1973 = MCMLXXIII 1974 = MCMLXXIV 1975 = MCMLXXV 1976 = MCMLXXVI 1977 = MCMLXXVII 1978 = MCMLXXVIII 1979 = MCMLXXIX 1980 = MCMLXXX 1981 = MCMLXXXI 1982 = MCMLXXXII 1983 = MCMLXXXIII 1984 = MCMLXXXIV 1985 = MCMLXXXV 1986 = MCMLXXXVI 1987 = MCMLXXXVII 1988 = MCMLXXXVIII 1989 = MCMLXXXIX 1990 = MCMXC 1991 = MCMXCI 1992 = MCMXCII 1993 = MCMXCIII 1994 = MCMXCIV 1995 = MCMXCV 1996 = MCMXCVI 1997 = MCMXCVII 1998 = MCMXCVIII 1999 = MCMXCIX

Older years in Roman numerals

Each hundred from 1000 to 1800, with three years people often look up: 1066, 1492 and 1776.

1000 = M 1066 = MLXVI 1100 = MC 1200 = MCC 1300 = MCCC 1400 = MCD 1492 = MCDXCII 1500 = MD 1600 = MDC 1700 = MDCC 1776 = MDCCLXXVI 1800 = MDCCC

Roman numerals for months and days

The months are I (January) to XII (December). Days run from I to XXXI:

1 = I 2 = II 3 = III 4 = IV 5 = V 6 = VI 7 = VII 8 = VIII 9 = IX 10 = X 11 = XI 12 = XII 13 = XIII 14 = XIV 15 = XV 16 = XVI 17 = XVII 18 = XVIII 19 = XIX 20 = XX 21 = XXI 22 = XXII 23 = XXIII 24 = XXIV 25 = XXV 26 = XXVI 27 = XXVII 28 = XXVIII 29 = XXIX 30 = XXX 31 = XXXI

How Roman numerals work

There are seven letters: I is 1, V is 5, X is 10, L is 50, C is 100, D is 500 and M is 1000. Write the value from the largest letter down and add them up: MDCCLXXVI is 1000 + 500 + 100 + 100 + 50 + 10 + 10 + 5 + 1 = 1776.

Six pairs subtract instead: a smaller letter just before a larger one is taken away from it. IV is 4, IX is 9, XL is 40, XC is 90, CD is 400 and CM is 900. That is why 1994 is MCMXCIV: M (1000) + CM (900) + XC (90) + IV (4).

The converter writes and reads standard form only. The largest number it can write is 3999, MMMCMXCIX; larger numbers used a bar over a letter to multiply it by a thousand, which does not survive as plain text. Spellings like IIII (found on many clock faces) are pointed out with their standard form rather than guessed at.

Did the Romans write dates like this?

No. The Romans named a year after the two consuls who held office in it, and some writers counted years from the founding of Rome. Days were counted back from three fixed points in each month: the Kalends, the Nones and the Ides, as in the Ides of March. Counting years from the birth of Christ (AD) came centuries later, so writing modern dates in Roman numerals is a style that came long after Rome, not a Roman practice. It is also why the converter starts at the year 1: there is no year zero and no Roman numeral for zero.
