List of date formats by country

Posted on by admin

The legal and cultural expectations for date and time representation vary between countries, and it is important to be aware of the forms of all-numeric calendar dates used in a particular country to know what date is intended.

Writers have traditionally written abbreviated dates according to their local custom, creating all-numeric equivalents to day-month formats such as “3 December 2025” (03/12/25, 03/12/2025, 03-12-2025 or 03.12.2025) and month-day formats such as “December 3, 2025” (12/03/25 or 12/03/2025). This can result in dates that are impossible to understand correctly without knowing the context. For instance, depending on the order style, the abbreviated date “01/11/06” can be interpreted as “1 November 2006” for DMY, “January 11, 2006” for MDY, or “2001 November 6” for YMD.

The ISO 8601 format YYYY-MM-DD (2025-12-03) is intended to harmonize these formats and ensure accuracy in all situations. Many countries have adopted it as their sole official date format, though even in these areas writers may adopt abbreviated formats that are no longer recommended.

The Unicode CLDR (Common Locale Data Repository) Project is the world’s largest repository documenting a wide variety of time and date representations for different countries and language groups.[1]

Basic components of a calendar date for the most common calendar systems:

  • D – day
  • M – month
  • Y – year

Specific formats for the basic components:

  • yy – two-digit year, e.g. 25
  • yyyy – four-digit year, e.g. 2025
  • m – one-digit month for months below 10, e.g. 3
  • mm – two-digit month, e.g. 03
  • mmm – three-letter abbreviation for month, e.g. Mar
  • mmmm – month spelled out in full, e.g. March
  • d – one-digit day of the month for days below 10, e.g. 7
  • dd – two-digit day of the month, e.g. 07
  • ddd – three-letter abbreviation for day of the week, e.g. Fri
  • dddd – day of the week spelled out in full, e.g. Friday

Separators of the components:

  • / – oblique stroke (slash)
  • . – full stop, dot or point (period)
  • – – hyphen (dash)
  • – space

This form is used in formal letters, academic papers, military, many media companies and some government documents, particularly in French-language ones.Federal regulations for shelf life dates on perishable goods mandate a year/month/day format, but allow the month to be written in full, in both official languages, or with a set of standardized two-letter bilingual codes such as 2019 AL 09 or 19 AL 09.

However, as it failed to establish itself, the traditional format (d)d.(m)m.(yy)yy was allowed again as an alternative in 2006 (except in areas where there is risk of ambiguity). The handwritten form d. mmmm yyyy is also accepted (compare DIN 5008).[citation needed] See Date and time notation in Europe.
