Overview
- Daylight saving time ends at 2 a.m. local time on Sunday, Nov. 2, when clocks are set back one hour, and most phones and computers will update automatically.
- Hawaii, most of Arizona, and the U.S. territories of Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Northern Mariana Islands stay on standard time year-round.
- An AP-NORC poll finds only 12% of U.S. adults support the current twice-yearly clock change, with most preferring a permanent time and a slight majority favoring year-round daylight saving.
- Nineteen states have passed laws to adopt permanent daylight saving time but cannot act without Congress, and a late-October Senate push to fast-track a national switch was blocked by Sen. Tom Cotton despite backing from President Donald Trump.
- Sleep specialists and medical groups endorse permanent standard time, and Stanford-led research published this year estimates sizable health gains under standard time, with experts recommending gradual schedule shifts and morning light to ease Sunday’s change.
