Daylight Saving Time Starts Overnight: Clocks ‘Spring Forward’ at 2 A.M.

WASHINGTON — Millions of Americans will lose an hour of sleep as daylight saving time begins at 2 a.m. on Sunday, March 9, 2025.

Clocks will “spring forward” by one hour, marking the transition to longer daylight hours in the evening.

The next time change will occur on Nov. 2, when clocks “fall back” to standard time.

Daylight saving time has been in place for more than 50 years, though efforts to make it permanent have repeatedly failed.

The Sunshine Protection Act, introduced in 2018 by Sen. Marco Rubio and Rep. Vern Buchanan, aimed to establish year-round daylight saving time. Despite passing the U.S. Senate in 2022, the bill stalled in the House. A 2023 attempt to revive the legislation also failed.

The U.S. has previously experimented with permanent daylight saving time, once during World War II and again in 1974, as a response to the energy crisis. 

While most states observe daylight saving time, Arizona and Hawaii remain on standard time year-round. Under federal law, states can opt out of daylight saving time but cannot independently adopt it permanently.

The time change means most electronic devices will update automatically, but some household appliances may require manual adjustments.
