Clocks across most of the United States will fall back one hour at 2 a.m. on Sunday, November 1, marking the end of Daylight Saving Time (DST) for 2025. The transition returns the country to Standard Time, which will remain in effect until March 14, 2026, when DST resumes.
A bipartisan bill to make DST permanent—the Sunshine Protection Act of 2025—passed the U.S. House of Representatives by a 308-117 vote on July 14, 2025, but has since stalled in the Senate. The legislation would eliminate the biannual clock change by locking the nation on DST year-round, though states would retain the option to opt out and remain on Standard Time permanently. President Donald Trump has publicly urged Senate Republicans to advance the bill, arguing in a social media post on October 26 that most Americans oppose changing clocks while favoring evening daylight.
Senate Republicans have not scheduled a vote, with Senate Majority Leader John Thune (R-S.D.) stating on October 15 that there is “no clear path forward or consensus.” Opponents, including Sen. Tom Cotton (R-Ark.), have cited concerns about darker winter mornings, particularly for schoolchildren, as a primary reason for resistance. Cotton wrote in an X post that Arkansans “don’t want their kids going to school in the pitch dark,” echoing similar objections raised during a 1974 temporary repeal of DST, which was abandoned after less than a year due to public backlash.
Eighteen additional states have passed laws to adopt permanent DST if federal legislation passes, but none can take effect without congressional approval. Arizona and Hawaii currently operate on permanent Standard Time, which is permitted under federal law. The Uniform Time Act of 1966 governs the current system, which has standardized DST start and end dates since 2007—the second Sunday in March to the first Sunday in November.
Health and sleep experts have raised concerns about the potential impacts of permanent DST, including disrupted sleep patterns and increased risks to mental health. Supporters of the change, however, argue that consistent evening daylight could reduce after-hours activity, including crime, and align better with modern schedules. Trump has claimed that permanent DST would shrink after-hours activity, though no peer-reviewed studies were cited in his statements.
Standard Time will remain in effect for the next four and a half months, with sunsets occurring earlier across the country. The next clock change—springing forward to DST—is scheduled for March 14, 2026, at 2 a.m. local time.
