Daylight saving time ends at 2 a.m. local time on Sunday, Nov. 1. Clocks across most of the US will turn back to 1 a.m., according to the National Institute of Standards and Technology.
The return to standard time means lighter mornings and earlier evening darkness by the clock. It also adds an extra hour that night, potentially giving you more time to sleep.
The switch follows Halloween. Before going to bed on Saturday, Oct. 31, move manual clocks back one hour. Remember bedside clocks, ovens, and vehicle dashboards. Most phones and computers adjust automatically when automatic time settings are enabled.
The change does not add or subtract daylight. It shifts sunrise and sunset to earlier clock times, as Time and Date explains.
Not every state takes part. Hawaii and most of Arizona stay on standard time year-round. The Navajo Nation observes daylight saving time, according to NIST.
Meanwhile, Washington has been considering competing approaches to the seasonal switch.
The House approved the Sunshine Protection Act by a 308–117 vote on Tuesday, July 14, according to the House clerk’s official tally. The proposal would make daylight saving time permanent, with exceptions for states opting out.
President Donald Trump supports the measure, which advanced to the Senate after the House vote.
Reps. Mary Gay Scanlon and Pat Harrigan introduced a different approach, the Sunshine for Our Kids Act. It would make standard time the default while allowing states to choose daylight saving time, according to the bill text.
The American Academy of Sleep Medicine favors permanent standard time because it aligns best with the body’s natural rhythms.
The central disagreement is which hours should get the light: permanent daylight saving time preserves later winter sunsets, while standard time provides earlier morning light.
The scheduled fall reset remains the date to mark on your calendar.
