Overview
- Most U.S. jurisdictions will set clocks back at 2:00 a.m. local time on Sunday, Nov. 1, 2026, returning to standard time and repeating the 1:00–2:00 a.m. hour.
- Several places do not change: Hawaii, most of Arizona, and U.S. territories such as Puerto Rico, Guam, American Samoa, the Northern Mariana Islands and the U.S. Virgin Islands will keep their clocks unchanged.
- Tribal and local exceptions create pockets of difference within states: the Navajo Nation observes the change while much of Arizona and the Hopi do not, so neighboring towns can have different times.
- Most phones, computers and many smartwatches will update automatically, but analog clocks, some car dashboards and certain appliances require manual resetting to avoid missed shifts, flights or appointments.
- Mexico’s 2022 time‑zone law keeps seasonal adjustments only in designated northern border municipalities, which will also roll back on Nov. 1 to stay synchronized with U.S. border partners while the Sunshine Protection Act remains pending in the Senate.
