Overview
- The United States returns to standard time on Sunday, November 1, 2026, when jurisdictions that observe daylight saving time set clocks from 2:00 a.m. back to 1:00 a.m.
- Federal rules require the change at 2:00 a.m. local time, which means the repeated 1:00–2:00 a.m. hour happens at different absolute times across time zones and can affect night shifts, transport logs, and booking systems.
- Key exceptions are in force: Hawaii, most of Arizona, Puerto Rico, Guam, American Samoa, the Northern Mariana Islands and the U.S. Virgin Islands do not change clocks, while the Navajo Nation within Arizona does observe DST.
- H.R. 139, the Sunshine Protection Act, cleared the House on July 14, 2026 but has not been enacted, so the November clock change stands and officials advise checking automatic date/time and time zone settings on phones, computers, vehicles and other devices.
- Spain and the EU have confirmed they will keep seasonal clock changes through at least 2031 with Spain shifting to winter time on the night of October 24–25, 2026, and the federal time system in the U.S. continues to let states opt out of DST rather than adopt permanent DST unilaterally.
