Google Calendar can display an event in different local times for different participants. Use an explicit event timezone when scheduling across countries or travelling. Changing a display preference is different from moving the actual appointment to another moment.

01 Check the calendar context
- Open Calendar settings and review the primary timezone. Add a secondary display timezone if it helps compare a colleague's working day.
- Open the event and inspect its start and end timezone settings.
- Enter the intended local time in the correct timezone, then verify the equivalent time for the other participant.
- Review recurring events around daylight-saving changes, especially when participants live in regions with different rules.
- Save and send an update if you intentionally changed the event time.
- Ask a representative guest to confirm the local time shown on their invitation.
02 Travelling with a phone
A mobile device may change its display timezone according to its settings. The appointment should still represent the same scheduled moment, but its displayed clock time can change. Review both the device and calendar settings before editing every event to compensate.
03 All-day events need a separate check
All-day holidays and deadlines are handled differently from an appointment with a start time. For a cross-border operational deadline, specify the relevant date, time and timezone in the description instead of relying only on an all-day label.
04 Example: one appointment, two displayed times
An appointment set for 10:00 UTC represents the same moment as 11:00 at UTC+01:00. If two guests see those times while using those respective display offsets, the event has not moved. Compare the event timezone and underlying appointment before making a correction.
Now suppose the organiser intends to move the actual meeting one hour later. Edit the original event to 11:00 UTC, save it and send the update. A guest using UTC+01:00 should then see 12:00. This example uses fixed offsets only; for real recurring meetings select the appropriate named timezone and review daylight-saving transitions where applicable. Include the timezone in any separate migration or customer handover message.
Why might two people see different Google Calendar event times?
Compare the timezone names, event details and whether one person has an old or duplicated invitation. Confirm that both displays refer to the same event. Do not create another meeting before establishing whether the difference is simply correct local-time conversion.
Include the timezone in human-readable communications for important appointments, such as a migration window. A phrase like 10:00 without a timezone can cause an avoidable outage or missed handover even when the calendar itself is configured correctly.
