Overview
- Daylight saving time ends at 2 a.m. local on Sunday, Nov. 2, shifting sunrise and sunset an hour earlier and giving most people an extra hour of sleep.
- An AP-NORC poll finds only 12% support the twice-yearly clock change, with 56% preferring year-round daylight saving and roughly 4 in 10 favoring permanent standard time.
- A Senate effort to fast-track permanent daylight saving stalled on Oct. 28, leaving in place 19 states’ contingent laws that can’t take effect without federal approval.
- Sleep experts and organizations including the American Academy of Sleep Medicine back permanent standard time, warning that the biannual switch disrupts circadian rhythms and raises health risks.
- Stanford-led research in PNAS estimates permanent standard time would yield the largest public-health gains, while the twice-yearly switching is the most harmful option.
