Schedule a recurring activity across multiple destination time zones.
The event first converts to UTC by subtracting the home offset, then each destination adds its own offset to display the matching local time. This anchors the schedule to a single reference. Thinking in UTC avoids the error of applying one offset to the wrong city when an activity spans several time zones.
Trip Schedule Across Zones
UTC = event hour - home offset; each destination = UTC + its offset
UTC = event hour - home offset; each destination = UTC + its offset The event first converts to UTC by subtracting the home offset, then each destination adds its own offset to display the matching local time. This anchors the schedule to a single reference.

This calculator takes 4 inputs: Event hour (24h) home, Home UTC offset, Destination 1 UTC offset, Destination 2 UTC offset. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
