Daylight Saving Time (DST) ends in Mexico on Sunday, October 27 at 2 a.m.
Clocks must be turned back one hour. Most people set their clocks before they head to bed for the night. DST in the United States and Canada doesn’t end until Sunday, November 3, so expats should be careful to make the necessary adjustments. Two Mexican states do not participate in Daylight Saving Time: Sonora and Quintana Roo. And 33 municipalities on the northern Mexican border, including Tijuana, Mexicali, Ensenada, Playa Rosarito and Tecate in Baja California, will wait until November 3 to set their clocks back.
