Washington, D.C.— Daylight saving time ends 2025 across the United States as Americans prepare to set their clocks back tonight. At 2:00 a.m. local time, clocks will “fall back” to 1:00 a.m., marking the official start of standard time that will last until spring. Whether you love the extra hour or dread earlier sunsets, here’s everything you need to know about the change, who it affects, and expert tips for a smooth transition.

What’s Changing for Daylight Saving in 2025?

At 2:00 a.m. tonight, nearly all of America will set clocks back one hour, launching the country into standard time for the next several months. Digital devices—like most phones and computers—will adjust automatically, but it’s important to manually check appliances, car dashboards, and wall clocks (USA Today). After the change, sunrise and sunset will occur about one hour earlier than the day before, impacting morning routines and evening activities (IndyStar).

Why Does the U.S. Still “Fall Back”?

Created to conserve energy and maximize daylight during World War I, Daylight Saving Time is now a hot topic. With modern lifestyles and technology, its relevance is widely debated. Many states—like Florida and California—have considered “locking the clocks” but need federal approval. Hawaii and most of Arizona already stay on standard time year-round (TimeandDate.com).

Health and Community Impact

Sleep experts warn that any time change may cause temporary grogginess and increased risk of accidents. Parents, shift workers, and students may need a few days to adjust. Advice from health officials includes going to bed earlier, checking alarms, and using the change as a safety reminder for smoke detectors and emergency kits (Des Moines Register).

The Ongoing DST Debate

Polls show most Americans want a permanent time—either standard or daylight. Legislative efforts have stalled, and meanwhile, the nation continues the twice-yearly shift (NY Post).
