House passes Sunshine Protection Act to make daylight saving time permanent, but Senate path uncertain

House vote

The US House of Representatives passed the Sunshine Protection Act on Tuesday with a 308-117 vote. The bill would make daylight saving time permanent nationwide, ending the twice-yearly ritual of moving clocks forward in spring and back in autumn. The vote drew bipartisan support, with Republicans and Democrats uniting behind the measure. President Donald Trump has championed the effort, describing clock-changing as a "ridiculous, twice yearly production" in a social media post in May. If enacted before November, Americans would not set clocks back to standard time this fall.

Legislative path

The bill, sponsored by Representative Vern Buchanan of Florida, had cleared the House Energy and Commerce Committee in May with a 48-1 vote. On Monday, the House Rules Committee advanced the bill on a 6-4 vote, setting up the full House vote. House leaders agreed to bring the measure to the floor partly as a concession to Representative Anna Paulina Luna, who had maintained a legislative blockade over a separate voting restriction bill. The Senate passed a similar daylight saving time bill in 2022, but it never advanced in the House.

State exemptions and readiness

Under the bill, states would have the option to remain on standard time year-round, preserving the existing exemptions for Hawaii and most of Arizona, as well as US territories including Puerto Rico, Guam, American Samoa, the US Virgin Islands, and the Northern Mariana Islands. Nineteen states have already enacted state-level laws to adopt permanent daylight saving time should Congress authorize it, according to the National Conference of State Legislatures. These laws have been contingent on federal permission, which this bill would provide.

Senate outlook

The bill now moves to the Senate, where its prospects are uncertain. A Senate GOP leader, who was not named by The New York Times, said it was unclear if the legislation could move forward. At least one Republican senator appears inclined to block it. The White House has expressed strong support, but the Senate calendar and procedural hurdles remain obstacles.

Historical context

Congress first established federal oversight of time zones with the Standard Time Act of 1918, and the Uniform Time Act of 1966 set the current daylight saving schedule. The last change to the country's clock-changing practices came in 2005, when legislation extended daylight saving time by several weeks. The practice, originally adopted during World War I to conserve energy and extend afternoon daylight, has been a subject of recurring debate. Sleep medicine specialists have argued that a fixed standard time aligns better with circadian rhythms, according to The Guardian.
