Overview
- Most of the country set clocks back one hour on Sunday, November 1, returning to standard time for the winter after months on daylight saving time.
- The Sunshine Protection Act, which the House passed in July to make daylight saving time permanent, remains blocked in the Senate and must be refiled if not passed before early January 2027.
- Several western Canadian jurisdictions adopted year‑round daylight time this fall, producing immediate cross‑border differences that have confused timetables, phone settings and business schedules.
- Medical and sleep experts generally favor permanent standard time as better for circadian health and safer for children, while studies show mixed road‑safety effects that trade reduced vehicle-occupant deaths against higher pedestrian and bicycle fatalities.
- The policy fight pits President Trump and business groups who back permanent DST against senators such as Tom Cotton who warn of very late winter sunrises, and it raises near-term issues for schools, transit timetables and software updates to calendars and devices.
