List of date formats by country

(Redirected from Date format by country)

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 "21 April 2024" (21/04/24, 21/04/2024, 21-04-2024 or 21.04.2024) and month–day formats such as "April 21, 2024" (04/21/24 or 04/21/2024). 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, and "2001 November 6" for YMD.

The ISO 8601 format YYYY-MM-DD (2024-04-21) 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.

For English speakers, MDY (mmmm-dd-yyyy) (example: April 9, 2019) is used by many English-language publications and media company products as well as the majority of government documents written in English.[34]

For French and English speakers, DMY (dd-mmmm-yyyy) is used (example: 9 April 2019/le 9 avril 2019). 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 JA 07 or 19 JA 07.
