Daylight saving time is one of the biggest sources of scheduling mistakes: clocks move an hour, but not everywhere and not on the same day. These pages tell you, for each region, whether DST is currently in effect, what the present UTC offset is, and the exact dates of the next spring-forward and fall-back transitions — all computed from the official IANA time zone database rather than hard-coded rules that go stale.
Knowing when a region changes its clocks helps you protect recurring meetings, travel plans, and deadlines that span borders. Choose a region below, then use Compare or the Meeting Planner to see how an upcoming change shifts the time difference with your own location.
