A travel event can start in one time zone and end in another. Google Calendar supports separate start and end zones so you can enter the confirmed local departure and arrival information. This is more reliable than applying a remembered offset to both ends of a journey.
Open separate-zone options
Create or edit the event on a computer and open Time zone beside its time fields. Enable Use separate start and end time zones, then select the correct regions. Google’s time-zone guidance describes this option for events with different endpoints.
Check dates as well as clocks
Enter the departure and arrival dates and local times from the confirmed itinerary. An overnight journey or an international date boundary can make the arrival date differ even when the visible clock time looks earlier. Do not infer duration from the local hour numbers alone.
Keep source itinerary details accurate and avoid exposing booking references or unnecessary personal information in a calendar shared with a broad audience.
Verify the saved interval
Reopen the event and compare both endpoints with the authoritative itinerary. Inspect how the journey appears in your usual calendar view and review any displayed duration. Confirm seasonal time-zone rules for the actual travel date rather than today’s offset. A correctly entered calendar event is a planning record, not confirmation that a transport service is operating or that the itinerary has not changed. Review later carrier updates separately and edit the existing event carefully rather than leaving several competing versions of the same journey.
