Date and time notation in Canada

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Date and time notation in Canada is regulated for some industries, and the Government of Canada recommends particular styles to ensure correct comprehension, especially in bilingual contexts. Everyday usage in Canadian English is a mixture of conventions from date and time notation in the United Kingdom and the United States, and varies across the country.[1]

Date[edit]

The Government of Canada recommends the YYYY-MM-DD format for writing numeric dates.[2] The Canadian Standards Association (National Standard of Canada CAN/CSA-Z243.4–89, All-numeric date and time) specifies ISO 8601 as the date format.[3] This is the only numeric date format that allows unambiguous interpretation.[4]

The YYYY-MM-DD format is an official recommendation, but it is rarely enforced, and in many contexts the DD/MM/YY and MM/DD/YY formats remain in use. Payments Canada prefers ISO 8601, but also allows cheques to be printed using MMDDYYYY or DDMMYYYY formats; they must include indicators to guide the format.[5] Some federal forms, such as commercial cargo manifests, offer a blank line with no guidance.[6]

Federal regulations for best before dates on perishable goods mandate that the year/month/day format be used, with the month spelled out. The year is only required if the date is beyond the current year. These are the official bilingual codes:[7]

Code English Name French Name
JA January janvier
FE February février
MR March mars
AL April avril
MA May mai
JN June juin
JL July juillet
AU August août
SE September septembre
OC October octobre
NO November novembre
DE December décembre

Time[edit]

Official bodies and many industries in Canada require the use of the 24-hour clock, and it is the recommendation of the Government of Canada.[8] Nonetheless, it only states that the system 'may be desirable', and the 12-hour clock remains common in English-speaking contexts.
