Week numbers in Google Calendar
To enable or display the ISO 8601 week number in Google Calendar, you typically need to adjust the view settings:
Settings > View Options > Check "Show week numbers"
* Ensure your system or application regional settings are set to follow ISO 8601 standards (weeks start on Monday) if the output varies.
Step-by-Step Instructions
- Open calendar.google.com in a browser and click the gear icon, then Settings.
- In the left menu choose "View options".
- Tick "Show week numbers".
- Return to the calendar: week numbers now appear in month view and in the mini calendar.
Good to Know
Google Calendar numbers weeks by your "Start week on" setting. For true ISO 8601 numbers, set the week start to Monday, otherwise the count can differ by one around New Year. The mobile apps inherit the web setting.
