Spain Prepares for Winter Time Change as European Schedule Extends to 2031

Spain and the rest of the European Union are preparing to transition to winter time during the early hours of Sunday, October 25, 2026. Clocks will be moved backward from 3:00 a.m. to 2:00 a.m. local time, except in the Canary Islands, where the shift will occur from 2:00 a.m. to 1:00 a.m. This adjustment grants an extra hour of sleep for residents, although evenings will experience an earlier sunset and significantly fewer hours of natural daylight.

Although the current Spanish regulatory calendar published in the Official State Gazette concluded with this October adjustment, the practice will continue. Because the European Union has failed to reach a consensus on whether to permanently adopt standard winter time or summer daylight saving time, the European Commission has established a new chronological framework spanning from 2027 to 2031. Consequently, Spain and neighboring European countries will maintain the biannual time changes for at least another five years.

The ongoing debate over abolishing the time change stems from a 2018 public consultation where 84 percent of participating European citizens voted in favor of ending the practice. Despite subsequent support from the European Parliament, the proposal stalled in the Council of the European Union. Member states remain deeply divided over which time zone to adopt permanently, with concerns regarding potential disruptions to transportation networks, telecommunications, and financial markets if neighboring countries select different permanent offsets.

The time shift often brings temporary disruptions to human circadian rhythms. According to Àngel Guirado, a psychologist and president of the Territorial Delegation of Girona at the Official College of Psychology of Catalonia, the abrupt modification can induce mild mental fatigue, irritability, and concentration difficulties similar to jet lag. However, he noted that the shift toward winter time can ultimately benefit sleep quality because earlier darkness triggers the natural release of melatonin earlier in the evening.

Health experts and scientific studies continue to examine the broader physiological impacts of time alterations. Research conducted by Stanford University and published in the Proceedings of the National Academy of Sciences indicates that seasonal time changes exert negative effects on public health, correlating with increased risks of cardiovascular issues and metabolic challenges. Scientific evidence generally favors adopting a permanent schedule, with a preference for standard winter time.

While the European Union and North America widely implement daylight adjustments—with specific exceptions such as Arizona and Hawaii in the United States—the practice remains relatively uncommon globally. Less than 40 percent of the world adjusts its clocks, with the vast majority of countries across Africa, Asia, and Latin America maintaining a fixed time throughout the entire year.
