Overview
- Spain will set clocks back one hour on Sunday, 25 October 2026, when 03:00 becomes 02:00 in peninsular Spain and 02:00 becomes 01:00 in the Canary Islands.
- The immediate effect is one extra hour overnight and earlier sunrises and sunsets afterward, which may disrupt sleep and routines for children, older adults and people with existing sleep problems.
- The date is recorded in Spain’s Orden PCM/186/2022 and rests on Real Decreto 236/2002, while the European Commission’s Communication C/2026/1660 fixes coordinated change dates for the EU through 2031.
- Sleep researchers and the Spanish Sleep Society broadly favour keeping standard (winter) time year‑round because morning light better aligns circadian rhythms, but many citizens prefer longer evening daylight and EU governments remain split on a permanent choice.
- Most internet‑connected devices will update automatically, yet many clocks and programmed appliances need manual adjustment, so experts advise checking alarms, timers and travel bookings that fall during the repeated hour.
