A Google Calendar can have a default time zone distinct from the primary zone used to view all calendars. Change the calendar-specific setting only when that calendar’s underlying regional context should change. Google’s guidance says this operation is for a calendar you own.
Open the calendar’s settings
On a computer, find the calendar under My calendars. Open its options and choose Settings and sharing. Confirm the calendar’s name, owner, and purpose before changing a setting that may affect how its schedule is interpreted.
Choose the intended zone
In that calendar’s settings, open Time zone. Search for the appropriate city or country and select the required region. Keep this separate from General’s Primary time zone, which controls your broader display context.
If you do not own the calendar, coordinate with the owner rather than assuming a visible shared schedule grants permission to change its regional settings. Do not create a public copy merely to obtain a zone control.
Verify representative entries
Inspect several existing events and the behavior of a new intended event after the change. Confirm actual dates and local times against their sources rather than assuming all historical and future entries should be rewritten. Review recurring meetings around seasonal clock changes. If the real requirement is simply to view a colleague’s schedule in your own local time, use the appropriate display-zone settings instead. A calendar-default change and a personal viewing preference solve different problems and should be documented accordingly. Confirm ownership before changing calendar defaults.
