Time in Canada

From Wikipedia, the free encyclopedia

Canada is divided into six time zones and ranks third among countries with respect to number of time zones, after Russia (eleven) and the United States (nine).

The province of Saskatchewan has a law prohibiting the use of daylight saving time (DST); however Lloydminster, partly located in this province, is exempted from this law.

[edit] Daylight Saving Time

Daylight saving time is observed in most provinces, and has since the late 1960s been closely or completely synchronized with its observance in the United States to promote consistent economic and social interaction. When the United States extended DST in 1987 to the first Sunday in April, all Canadian provinces followed suit to mimic the change.

The latest United States change, adding parts of March and November, has not yet been adopted by all Canadian provinces, with one province apparently choosing not to change.
