Daylight Saving Time ends in the U.S. at 2 a.m. E.T. on Sunday, Nov. 1. That's when clocks will be set back one hour, after they were set forward one hour for the start of Daylight Saving Time on March 8.
That means an extra hour of sleep before waking up on Sunday morning. It will also mean lighter mornings—but darker evenings. This applies for almost all of the U.S.—Arizona and Hawaii have opted out of Daylight Saving Time.
