US Daylight Saving Time Ends Sunday, Clocks Fall Back an Hour
Daylight saving time concludes at 2 a.m. local time on Sunday, when most US clocks move back to 1 a.m., giving people an extra hour of sleep overnight. Standard time will remain in effect until clocks spring forward again on March 14, 2027. Phones and computers adjust automatically, but devices like ovens, microwaves and car clocks typically require manual changes.
