When are Daylight Saving Time changes in 2025? Will Washington state be participating?

Sometimes it feels like every year we hear promises of doing away with Daylight Saving Time, and yet every year we continue to adjust our clocks twice a year.

Current President Donald Trump has publicly stated his intentions to eliminate Daylight Saving Time, though no concrete steps have been taken yet.

Still, 2025 is no different. Despite all the talk of doing away with the biannual change, we’ll have to continue the practice for at least one more year.

Here’s when we’ll be changing our clocks, and what to know about the pending legislation.

Daylight Saving legislation in Washington

Daylight Saving Time has been the standard across the U.S. since 1966. That year, the Uniform Time Act was enacted, following the creation of the Department of Transportation. The department and the subsequent Uniform Time Act were made in response to rising transportation needs in the country.

Standardized times systems were put in place for the benefit of national transportation.

Per the legislation, state governments cannot alter their time zones, nor change the dates associated with Daylight Saving Time. States can, however, independently exempt themselves from observing Daylight Saving Time. Currently, all states except Hawai’i and Arizona (except for the Navajo Nation territories) observe Daylight Saving Time. Numerous U.S. territories have opted out as well.

Because states cannot alter when Daylight Saving Time is in effect, it is not possible for a state to enact permanent Daylight Saving Time. Instead, Hawai’i, Arizona and territories opting out of the practice observe permanent standard time.

Federal legislation to update these standards passed in the Senate in 2022, but didn’t make it through the House of Representatives before the end of the legislative session. No legislation has made it through in the time since.

Attempts to change Daylight Saving standards

Washington is among a handful of states that passed legislation to immediately make Daylight Saving Time permanent if federal standards are updated. While Governor Inslee signed off on the permanent update in 2019, the practice will continue in the Evergreen State until federal standards are updated.

The proposal has been reintroduced by Senators Patty Murray (D-Wash.) and Rick Scott (R-Fla.), with the support of 13 other senators.

When is Daylight Saving Time 2025?

On March 9, clocks will jump forward one hour. Daylight Saving Time ends on November 2. Both clock changes occur at 2 a.m., becoming 3 a.m. and 1 a.m. respectively.
