Topline

What time is it tomorrow morning? For most of the U.S. and Canadians, there will be two 1 a.m. hours. Daylight saving time ends overnight tonight, with clocks turning back one hour early Sunday, Nov. 1. The change brings an extra hour overnight — but also shifts sunrise and sunset about an hour earlier by the clock. Falling back to standard time is good for those who like more morning light, but bad for those who hate early evening darkness.

Key Facts

  • Daylight saving time ends at 2 a.m. local daylight time on Sunday, Nov. 1, across most of the U.S. At that moment, clocks turn back to 1 a.m. local standard time, according to Timeanddate.com.
  • Most smartphones, computers and other internet-connected devices will likely change automatically, but traditional clocks and some watches, ovens, microwaves and vehicle clocks may need to be reset manually.
  • Hawaii and most of Arizona do not observe daylight saving time, while the Navajo Nation in Arizona does. Several U.S. territories also remain on standard time year-round.
  • Daylight saving time will begin again on Sunday, March 14, 2027, according to Timeanddate.com. An easy way to remember how the system works is “spring forward, fall back.”
  • A Gallup survey in 2025–2026 with three choices found that 48% favor permanent standard time, 24% permanent DST and 19% keeping the current system, according to Newsweek.

WHEN EXACTLY DO THE CLOCKS GO BACK?

The change happens in the middle of the night. At 2 a.m. local daylight time on Sunday, Nov. 1, clocks move backward to 1 a.m. local standard time. In New York, for example, 1:59 a.m. EDT will be followed not by 2 a.m., but by 1 a.m. EST. That will happen across the time zones in turn, so not everywhere will change to standard time simultaneously.

BIG NUMBER

25 hours. That’s effectively how long Sunday lasts for anyone whose clocks go back. Turning clocks from 2 a.m. to 1 a.m. repeats an hour, which is why the autumn clock change is often associated with getting an “extra hour” overnight. If you’re going to bed before 2 a.m., the simplest approach is to change the clocks before you go to sleep the night before the change.

WHAT WILL THE CLOCK CHANGE DO TO SUNRISE AND SUNSET?

The amount of daylight doesn’t suddenly change on Sunday — only what the clock says when daylight occurs. Returning to standard time moves both sunrise and sunset roughly one hour earlier by the clock. For example, in New York on Oct. 31, sunrise is at 7:25 a.m. EDT, and sunset is at 5:53 p.m. EDT. On Nov. 1, sunrise is at 6:26 a.m. EST and sunset is at 4:52 p.m. EST. It means brighter mornings, but noticeably earlier darkness in the late afternoon and evening.

What states and Provinces Don’t Observe DST?

Two U.S. states do not observe daylight saving time. Arizona remains on Mountain Standard Time year-round (except in the Navajo Nation, which observes DST), while Hawaii permanently uses Hawaii Standard Time. DST is not used in the U.S. territories of American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands.

In Canada, DST is not observed in Yukon, most of Saskatchewan, some regions of British Columbia, Southampton Island in Nunavut and some communities in eastern Quebec. Alberta will not turn its clocks back on Nov. 1, 2026, having adopted permanent Alberta Time (previously called Mountain Daylight Time), according to Timeanddate.com.
