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 "11 December 2023" (11/12/23, 11/12/2023, 11-12-2023 or 11.12.2023) and month–day formats such as "December 11, 2023" (12/11/23 or 12/11/2023). 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.

Canada ✅ ✅ ✅ yyyy-mm-dd is the only format that the Government of Canada and Standards Council of Canada officially recommend for all-numeric dates. However, usage differs with context. mmmm-dd-yyyy is used by many English-language publications and media company products as well as the majority of government documents written in English. 


dd-mmmm-yyyy is used for French and English speakers. 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.
