Overview

• Clocks move back one hour at 2:00 a.m. local time on Sunday, Nov. 2, returning to standard time until March 8, 2026.
• Most of the United States observes the change, while Hawaii, most of Arizona, Puerto Rico, Guam, the Northern Mariana Islands, American Samoa and the U.S. Virgin Islands remain on standard time year-round.
• Phones, smartwatches and computers typically update automatically, but analog clocks in homes and vehicles require manual adjustment.
• California and Florida have pursued permanent daylight saving or fixed-time policies, but those changes cannot take effect without approval from Congress.
• The U.S. Department of Transportation oversees time-zone rules under the Uniform Time Act, and recent proposals, including Senator Rick Scott’s 2025 push, have not secured federal enactment.
