Americans will still be required to change their clocks this fall, but Congress could soon revisit legislation that would eliminate the twice-yearly switch and make daylight saving time permanent nationwide. The Sunshine Protection Act would repeal the federal provision that establishes the seasonal period of daylight saving time.

The House has advanced legislation this year, while the Senate has yet to complete action. President Donald Trump has expressed support for making daylight saving time permanent, adding White House backing to a proposal that has been debated in Congress for several years.

The issue has also gained support at the state level. Nineteen states have enacted laws or resolutions calling for year-round daylight saving time, although many of those measures cannot take effect unless Congress changes federal law or neighboring states take similar action.

Florida became the first state to enact legislation calling for permanent daylight saving time in 2018. Other states that have approved similar measures include Alabama, Colorado, Delaware, Georgia, Louisiana, Maine, Minnesota, Mississippi, Montana, Oklahoma, South Carolina, Tennessee, Utah, Washington, Wyoming and Idaho. Several of those laws contain conditions requiring neighboring states to adopt the same system.

States have taken different approaches to the issue. Hawaii and most of Arizona already remain on standard time year-round, which federal law permits. Other states have considered legislation to make standard time permanent rather than daylight saving time.

Several additional states considered permanent daylight saving time measures during the current legislative cycle but did not enact them. Legislation has also been introduced in states including New Jersey and Pennsylvania, where neighboring-state decisions could affect whether existing measures take effect.

For now, the federal system remains unchanged. Unless Congress acts, most Americans will move their clocks back one hour on Nov. 1, 2026, returning to standard time for the winter months. The Sunshine Protection Act would change that system by keeping daylight saving time in place throughout the year.
