Most devices change by themselves

Phones and computers that set their time automatically switch on their own, and so do the clocks on this site. Check alarms, timers and anything scheduled for the hour that repeats or disappears.

Time differences that shift

Countries change on different dates, and the northern and southern hemispheres change in opposite seasons, so the gap between two cities moves during the year. Short in-between spells are marked.
