The first day of the week in Google Calendar affects how dates are arranged in weekly and monthly planning. Set it to match your working convention, then verify the resulting date labels. The preference does not change the weekday or actual date of an existing event.
Find the view preference
Open Google Calendar on a computer and choose Settings > Settings. Select View options. Google’s guidance identifies the week-start choice among the settings available in this section and says changes are saved automatically.
Choose the appropriate starting day
Select the week-start option that matches the calendar convention you intend to use. Check the setting’s label before changing another regional or date-format preference. A regional display choice and an event’s actual time zone are separate settings.
When collaborating across regions, refer to explicit dates in messages and meeting descriptions instead of relying only on phrases such as “the first day next week.” People can use different display conventions while viewing the same event.
Verify dates rather than positions
Return to a week or month view and inspect a known event’s weekday and date. Confirm the beginning and end of the displayed row before planning a deadline. Do not move an event simply because its column changed after the preference adjustment. If a printed calendar will be distributed, inspect the actual print preview as well. A consistent visual convention helps planning, but it does not resolve an ambiguous deadline or guarantee that another person’s calendar display uses the same first day.
