Spain Transitions to Winter Time with Clock Change Amid Ongoing Debate

On Sunday, October 26, 2025, Spain will set clocks back one hour at 3:00 a.m., marking the start of winter time and resulting in a 25-hour day. This change applies nationwide, including the Balearic and Canary Islands, maintaining the traditional one-hour difference with the mainland. The adjustment aims to optimize daylight use and reduce energy consumption, though recent studies indicate the energy savings are minimal. This practice, mandated by Royal Decree 236/2002, is published years in advance in the Official State Bulletin and remains in place as the European Union has yet to reach a consensus on abolishing daylight saving time.

Prime Minister Pedro Sánchez has proposed ending the biannual time change to the Council of Europe, citing its limited benefits and health concerns. Health experts are divided, with some asserting the change aligns with human biology and has minor effects, while others warn it can worsen sleep disorders, particularly in children and elderly people. A recent CIS survey found that 66% of Spaniards prefer permanent summer time, despite medical recommendations favoring a fixed winter time.

To ease the transition, authorities advise going to bed earlier before the change, avoiding screens before sleeping, and embracing natural morning light. While most digital devices update automatically, analog and offline clocks need manual adjustment before bedtime on October 25. The next scheduled clock changes will be in March and October 2026, which may be the last if the EU agrees to eliminate the practice.
