Overview
- The switch to standard time occurs overnight from Saturday to Sunday, 25–26 October, with clocks set from 03:00 back to 02:00.
- Many central heating timers do not update automatically, risking mistimed night setbacks, higher bills and chilly evenings unless manually corrected; slow-responding underfloor systems may not benefit from nightly setbacks.
- Most smartphones, computers and radio-controlled clocks update on their own, but analog clocks, basic digital alarms and some ovens, microwaves and older car radios require manual adjustment.
- Public transport operators adjust for the repeated hour, with local schedules such as in Bochum adding services that run once under summer time and again under winter time.
- Spain is pressing for an EU-wide end to the time change as studies find negligible energy savings and health experts warn of sleep and safety effects, and the Commission says its analysis will begin soon while the current system remains in force.
