Overview
- Most of the United States advances clocks from 2:00 a.m. to 3:00 a.m. on Sunday, March 8, 2026, and returns to standard time on Sunday, November 1, moving from 2:00 a.m. to 1:00 a.m.
- Hawaii, most of Arizona (except within the Navajo Nation), and U.S. territories including Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands and the Northern Mariana Islands do not observe the switch.
- The schedule is set by federal law under the Uniform Time Act and the Energy Policy Act of 2005; many states have passed measures favoring permanent DST but cannot implement them without Congressional approval.
- Residents should expect a one-hour loss of sleep at the March change and are advised to verify travel, work and school schedules, especially when crossing state or tribal boundaries.
- Most phones, computers and smartwatches update automatically, while microwaves, ovens, wall clocks and many older car systems require manual adjustment.
