The daylight saving time adjustment in Spain is scheduled for the early hours of Sunday 29 March 2026. At 02:00, clocks on the mainland and Balearics will be advanced one hour to 03:00. Meanwhile, in the Canary Islands, the change occurs at 01:00, moving forward to 02:00. This twice-yearly shift means residents will lose an hour's sleep but benefit from extended daylight during the evening.
This transition to summer time will remain in effect until Sunday 25 October 2026, when Spain will revert to standard time. On the day clocks change, the official time will last 23 hours instead of the usual 24, postponing sunrise and sunset to maximise late afternoon natural light. This adjustment may help reduce energy consumption during warmer months.
This upcoming change may be among the last seasonal clock adjustments in Spain and across Europe. The current timetable is regulated by order PCM/186/2022, dated 11 March, covering daylight saving periods from 2022 to 2026. Spain’s proposal to end these biannual clock changes permanently has yet to receive final approval from European institutions.
Legal framework governing clock changes in Spain
The system currently in place originates from Royal Decree 236/2002 of 1 March, which incorporated European Directive 2000/84/EC from 19 January 2001 into Spanish law. This directive harmonises daylight saving time across all EU member states, ensuring clocks change simultaneously for smoother trade, communication, and transport. Its primary goal is to promote energy saving through optimised use of natural light. According to the directive, clocks must move forward on the last Sunday in March and revert on the last Sunday in October every year.
In 2018, the European Commission conducted a public consultation involving 4.6 million participants, with 84% favouring an end to the twice-yearly clock changes. The Commission proposed stopping this practice from 2021 onwards, allowing member states to adopt either permanent summer or winter time. Despite this, Spain's plan to end daylight saving time has faced obstacles, mainly due to a lack of consensus among EU countries on selecting a uniform permanent time. There are concerns over potential disruption to commerce and cross-border coordination if neighbouring nations choose differing time zones. Notably, Spain is geographically aligned with Greenwich Mean Time but has observed Central European Time since 1940.
Effects of clock changes on health and society
Scientific research has explored the health consequences of switching clocks. Alterations to circadian rhythms have been linked to sleep issues, increased cardiovascular risks, mood variability, and temporary declines in work and academic performance. Vulnerable groups include children, older adults, and individuals with chronic health conditions. Furthermore, the actual energy savings from daylight saving remain contested. Though originally introduced to reduce energy use, recent analyses question its effectiveness given modern consumption trends dominated by air conditioning, heating, and electronic devices.
The idea of daylight saving time dates back to Benjamin Franklin’s 1784 proposal aimed at conserving resources. However, it was widely adopted only during the First World War, when several European countries used it to decrease coal consumption. After various intermittent changes, the European Union standardised the practice in 2001 through its directive, which still governs time changes in Spain and other member states.
The next clock change in Spain will occur on Sunday 25 October 2026. At 03:00, clocks on the mainland and Balearics will move back one hour to 02:00. In the Canary Islands, the adjustment happens at 02:00, reverting to 01:00. This switch will allow people to "gain" one hour of sleep, making the day officially last 25 hours instead of the usual 24.
