FAQ

When do the clocks change in Switzerland?

Sunday, 25 October 2026, at 03:00 local time, when clocks go back one hour.

Why does the time difference to other countries wobble?

Countries change their clocks on different dates — Europe and North America are a week or more apart — so for a few weeks each spring and autumn the usual difference is temporarily an hour off. Every overlap and difference figure on this site reads the current offsets from the IANA time-zone database, so those weeks are handled automatically.
