Fix sync problems with the Google Calendar app

Important: To find your Google Calendar events in a different calendar application, like Apple Calendar or Outlook, the instructions for syncing are different:

• Learn how to add Calendar events to Apple Calendar
• Learn how to sync Calendar with computer programs

Events that you create in Calendar appear across all devices where you're signed in. If you can't find your events in the Calendar app, review your settings.

Try these common fixes first

Important: The Calendar app only syncs past events up to one year. To find past events beyond a year, go to calendar.google.com.

Follow these steps on the device that you're using the Calendar app on.

1. Check your Internet connection

• On your mobile device, check that data or Wi-Fi is on and you're not in aeroplane mode.
• Open a browser app and try a web search.

2. Update the Calendar app

• Make sure that you're using the Calendar app .
• In your device's app store, update the Calendar app.

3. Check that the Calendar is visible

1. On your phone or tablet, open the Calendar app .
2. At the top left, tap Menu .
3. To the left of the calendar's name, make sure that the box is ticked.

4. Make sure that new events are being added to your Google Calendar

If you add an event to a calendar that's not associated with your Google Account, it might not show up in the Calendar app or on calendar.google.com. When you create an event, check the account to which you add events.

1. Open the Google Calendar app .
2. At the bottom right, tap Create .
3. At the top of the event, check that the calendar that it's added to is associated with your Google Account.
