Overview
- Spain will revert to winter time in the night from Saturday 24 to Sunday 25 October 2026 when peninsular clocks go from 03:00 to 02:00 and Canary Islands clocks go from 02:00 to 01:00, creating a 25-hour day.
- The European Commission published a harmonized interim calendar for seasonal changes through 2031 after member states failed to agree on a permanent single time.
- Daylight Saving Time in the United States will end on Sunday 1 November 2026 at 02:00 local time when most states set clocks back to 01:00 because the Sunshine Protection Act stalled in the Senate.
- Local exceptions will complicate coordination: the Canary Islands shift an hour earlier than peninsular Spain and U.S. areas such as Hawaii, most of Arizona and several territories do not change clocks while the Navajo Nation follows DST inside Arizona.
- Practical impacts include an extra hour of sleep where the change is observed, automatic updates for most internet-connected devices, and the need for travelers and businesses to check local rules because Spain’s time reflects a long-standing shift from its geographic solar time.
