Overview
- Clocks in most U.S. jurisdictions shift from daylight saving to standard time on Sunday, Nov. 2, 2025 at 2:00 a.m. local, when they move back to 1:00 a.m., with standard time in place until March 8, 2026.
- Hawaii, most of Arizona (except the Navajo Nation), Puerto Rico, American Samoa, Guam, the Northern Mariana Islands and the U.S. Virgin Islands do not change their clocks.
- Mexico City and most of Mexico do not observe seasonal clock changes, but designated border municipalities in Baja California, Chihuahua, Coahuila, Nuevo León and Tamaulipas will adjust on Nov. 2 to align with the U.S.
- The Uniform Time Act governs the U.S. schedule and the Department of Transportation oversees time zones, while state efforts to adopt permanent daylight saving time remain stalled without Congressional approval.
- Most phones, computers and smartwatches update automatically, but analog clocks and many appliances—such as microwaves, ovens and car dashboards—must be set by hand.
