Google uses a universal calendar system where it syncs your calendar details across all your devices. When the Calendar app stops syncing on a device, you can’t view newly added events on that device. 

There are many reasons Google Calendar may not sync on your devices. Maybe your phone doesn’t have enough space to store new calendar details. Or maybe you or someone else has disabled the sync feature. We’ll show how to fix these common issues with Google Calendar not syncing.

    Enable The Calendar Sync On Your Device

    Enable Syncing For Your Google Calendar

    The Google Calendar app has an option to enable and disable sync for individual calendars. If this option is set to disabled for your calendar, that’s why your Google Calendar is not syncing. Turning this option on will make that calendar sync with the Google servers.

    2. Tap the three-dots at the top-right corner of your screen.
    1. Tap the only option that says Refresh and your calendars will be updated with the new event details.

    Enable Calendar Storage On Your Phone

    On most Android phones, you have an option that lets you specify storage permissions for various apps. If this option is disabled for the Calendar app, that may be why the app isn’t syncing your calendars.

    To allow the app to use your phone’s storage:

    Ensure You Have Enough Free Space On Your Device

    When you sync your calendars, new information is usually added to your calendars. This uses your phone’s storage so you must have enough storage available to store the updated Google calendars on your device.
