Overview
- Clocks in jurisdictions that observe Daylight Saving Time will be set back one hour at 2:00 a.m. local time on Sunday, November 1, 2026, returning those areas to standard time.
- Hawaii, most of Arizona and several U.S. territories will not change clocks, and nearby tribal differences persist because the Navajo Nation observes DST while the Hopi Nation does not.
- The Sunshine Protection Act (H.R. 139) was approved by the House on July 14, 2026 but has not been enacted by the Senate, so it does not affect the November 1 transition.
- Mexican northern border municipalities such as Tijuana and Mexicali will also revert clocks on November 1 to stay synchronized with U.S. border partners under Mexico’s border time rules.
- Many phones and computers update automatically but users should check automatic date, time and time-zone settings, verify travel reservations and confirm shift or appointment times because the next DST start under current law is scheduled for March 14, 2027.
