Date Format by Country 2024

  • Abbreviations: d = day, m = month, and y = year
  • Common separator marks include dashes (-), forward slashes (/) and periods (.)
  • Parenthesis indicate multiple accepted variations. For example, dd.mm.(yy)yy means both dd.mm.yy and dd.mm.yyyy are acceptable.
  • Capital letters represent the general order in which day, month, and year are shown. Ex: YMD = year, month, day.
  • Knowledge of date orders helps prevent misunderstandings. For example, 02-06-12 means February 06, 2012 in MDY; June 02, 2012 in DMY; and June 12, 2002 in YMD.
  • Lower-case letters represent the precise formula in use.
  • A single letter indicates single-digits when possible, but double-digits otherwise. Ex: d-m-yy = 1-1-24, but also 10-31-24
  • Two letters indicates a two-digit numerical abbreviation. Ex: mm-yy = 01-24
  • Three letters indicate a three-letter written abbreviation. Ex: mmm-yyyy = Jan-2024
  • Four letters indicate a four-digit year or the full name of the day or month. Ex: dddd mmmm yyyy = Monday 01 January 2024
