Daylight saving and meeting plans

Many regions change clocks seasonally. The date of the change differs by country, and some places do not observe daylight saving at all.

ZoneFold asks for a specific meeting date so conversions can use that day’s rules from the IANA timezone database in your browser. When you plan a recurring series that crosses a clock change, re-check the overlap around the transition week.
