March 13, 2016: USA and Canada will switch to summer time

The days are getting longer, and it is time for daylight saving time to start. In the USA and Canada, it starts on Sunday 13 March 2016: the clocks go forward one hour during the night between Saturday and Sunday. At 02:00 local time on Sunday morning, the clocks are turned forward to 03:00.^[1][2]

Not every part of the United States and Canada uses daylight saving time: wide areas, such as Hawaii, most of Arizona and most of Saskatchewan, stay on standard time all year.^[1][2] The main idea of daylight saving time is to move an early-morning hour, which many of us sleep through, to the evening. By the clock, the sun then rises an hour later and sets an hour later.

Update, 26 October 2026: The US rule is still the same: clocks go forward one hour at 02:00 on the second Sunday of March; in 2026 that was 8 March 2026.^[1] Canada has changed a lot: Yukon stopped changing its clocks in 2020, and in 2026 British Columbia, Alberta, the Northwest Territories, Manitoba and northwestern Ontario stopped too; they keep their summer time all year.^[2] See also: USA and Canada start daylight saving time on March 10, 2013.
