The U.S. House of Representatives passed the Sunshine Protection Act on Tuesday in a bipartisan 308-117 vote, advancing legislation that would make daylight saving time permanent and eliminate the twice-yearly clock changes. President Trump has backed the measure, calling it "great news for America."
If enacted, the bill would lock the country into the time currently observed from March to November year-round, with individual states able to opt out. Supporters point to research linking the biannual clock change to worse sleep and more workplace and car accidents in the days after it happens, plus potential economic benefits from extra evening daylight.
The bill now moves to the Senate, where its path is uncertain. Arkansas Senator Tom Cotton has already opposed it, citing the effect permanent daylight saving time would have on children in northern states, who would walk to school before sunrise for much of winter.
Canada has already seen movement on the issue. British Columbia made the switch in March 2026, adopting permanent daylight saving time. Alberta followed a few months later with "Alberta Time" (Mountain Daylight Time year-round), set to take effect in November 2026. The Northwest Territories has said it plans to do the same. Yukon switched in 2020, and Saskatchewan has effectively been on permanent daylight time for decades, running on Central Standard Time all year. Quebec ran a public poll in October 2024 asking residents whether they'd prefer one consistent time but has not acted since.
