Overview
- Spain will revert to winter time overnight Saturday into Sunday, October 24–25, 2026, when clocks on the peninsula and Balearic Islands move from 03:00 back to 02:00 and in the Canary Islands from 02:00 back to 01:00.
- In the United States the end of daylight saving time falls on Sunday, November 1, 2026, when local clocks in observing jurisdictions set back from 02:00 to 01:00, creating a repeated 1:00–2:00 a.m. hour that can affect flights and early appointments.
- Some U.S. places do not change clocks: Hawaii, most of Arizona and several territories (Puerto Rico, Guam, American Samoa, Northern Mariana Islands, U.S. Virgin Islands) stay on the same time year‑round while the Navajo Nation continues to observe DST.
- Most modern smartphones, computers and connected systems update automatically if set to the correct time zone, but many wall clocks, ovens, car dashboards and other offline devices require manual resetting to avoid missed alarms and schedule errors.
- Lawmakers have proposed ending seasonal shifts but no federal or EU change has taken effect yet; the U.S. House approved the Sunshine Protection Act on July 14, 2026, and Spain’s official calendar remains the public guide for upcoming years, so travelers and employers should confirm local times now.
