Daylight Saving Time begins at 2:00 a.m. local time on the first Sunday in April. On the last Sunday in October area on Daylight Saving Time fall back to Standard Time at 2:00 a.m. The names in each time zone change along with Daylight Saving Time. Eastern Standard Time (EST) becomes Eastern Daylight Time (EDT), and so forth. Some areas of Canada not using Daylight Saving Time include, Fort St. John, Charlie Lake, Taylor and Dawson Creek in British Columbia, Creston in the East Kootenays, and most of  Saskatchewan (except Denare Beach and Creighton).
