Overview
- The 2026 Daylight Saving Time period runs from Sunday, March 8 at 2:00 a.m. local time, when clocks advance to 3:00 a.m., through Sunday, November 1, when clocks return to 1:00 a.m.
- Most U.S. states will change clocks, while Hawaii, most of Arizona (with the Navajo Nation observing DST), and territories including Puerto Rico, Guam, American Samoa, the Northern Mariana Islands and the U.S. Virgin Islands will not.
- Thirty-six Mexican border municipalities, including Tijuana, will advance clocks on March 8 to remain synchronized with neighboring U.S. cities such as San Diego.
- Airlines, transit systems and digital devices generally update automatically, but authorities advise checking and adjusting manual clocks in homes, vehicles and critical systems.
- The U.S. Department of Transportation oversees the national observance, and proposals to make DST permanent, such as versions of the Sunshine Protection Act and state measures, remain pending without changes to the 2026 schedule.
