The United States and Canada will begin this year's Daylight Saving Time (DST) period on Sunday, March 10, 2013. Millions of people will have to turn their clocks one hour ahead from 2am (02:00) to 3am (03:00) local time. Some areas in the United States and Canada do not observe DST.
Clocks in areas that follow DST will be returned to standard time on November 3, 2013 at 2am (02:00) local time.
Areas exempt from DST
While most U.S. states and territories use DST during part of the year, some areas will not follow the switch:
- American Samoa
- Puerto Rico
- The United States Virgin Islands
- Most of Arizona except the Navajo Nation Community
Areas that do not observe DST in Canada include:
- Some regions in Québec, east of 63° west longitude (e.g. Blanc-Sablon)
- Most of Saskatchewan
- Southampton Island
- Some areas in British Columbia (e.g. Creston)
Mexican Border Cities follow U.S.
Mexico’s northern border cities, like Juarez City (Ciudad Juárez), will follow the United States' DST schedule. However, most of Mexico, including the capital Mexico City, will set their clocks 1 hour forward 4 weeks later, on Sunday, April 7, 2013.
