Overview
- Daylight saving time ends at 2 a.m. local time on Sunday, Nov. 2, when most U.S. clocks move back one hour to standard time.
- Sen. Tom Cotton blocked a unanimous‑consent bid to pass the Sunshine Protection Act, freezing federal efforts to make daylight saving time permanent.
- States may choose permanent standard time now, but they cannot shift to permanent daylight saving time without federal authorization, and several state proposals have stalled.
- Medical and sleep‑science groups urge ending the biannual clock changes and generally favor permanent standard time, with new Stanford modeling suggesting it offers a slight health advantage over permanent daylight saving time.
- Polling shows strong support for ending the switching but a split on the replacement, and sleep experts advise morning light and consistent schedules to ease the fall transition.
