Overview
- Most of the United States set clocks back one hour on Sunday, Nov. 1, returning to standard time while the House-passed Sunshine Protection Act sits stalled in the Senate.
- Senators face limited floor time and must overcome a 60-vote procedural threshold to advance the bill, which would lapse in early January 2027 if Congress does not act.
- President Trump has publicly pressed the Senate to pass the measure and urged calls to holdouts, while Sen. Tom Cotton and other opponents warn year-round daylight saving time would produce very late winter sunrises and raise safety concerns for children.
- The House bill’s current language would immediately shift clocks one hour forward if signed now, a provision that heightens political and technical concerns about sudden changes to schedules, devices, and transportation systems.
- Medical and sleep experts largely favor permanent standard time because it better matches human circadian rhythms, and the recent decision by several Western Canadian jurisdictions to keep daylight time year-round has created cross-border timing confusion that highlights practical risks.
