How to Fix Google Calendar Sync Issues

Calendly, July 12, 2020

Google Calendar is one of the most ubiquitous apps out there for managing our daily lives. It lives on our phones and connects with our emails, among other accounts.

Google Calendar’s ability to sync across devices lets you input events, reminders and notes from just about anywhere. You can then pull up your personal and work schedules at a moment’s notice, whether that’s on your mobile, laptop, desktop or tablet device. We take having our schedule within arm’s reach at all times for granted. 

So what happens when the Google Calendar sync function doesn’t work? What happens when you enter an event and it isn’t accessible from another device? This issue can interfere with your ability to keep track of what’s going on in your life.

Here we’ll go over several ways you can fix sync issues with Google Calendar so you can get back on track. The method you use will depend on the device and operating system you use. We’ll start with Apple’s iOS.

How to Fix Google Calendar Sync Issues on an iPhone or iPad

Re-add Your Google Calendar Account

One of the easiest fixes for Google Calendar sync issues on an iOS device is to remove your Google account from the app and add it back again. Removing your account is a simple process:

  1. Open the Google Calendar app on your iOS device.

  2. Select the menu icon from the top left corner of the screen.

  3. Choose Settings (look for the little gear-shaped symbol).

  4. Select Manage Accounts.

  5. Tap Edit.

  6. Look for and select the option to remove your account.

  7. Confirm and press Done.

At this point, you won’t be able to use Google Calendar on this device — since your account is gone — but don’t panic. Just close and reopen the app and you’ll automatically be invited to reconnect your account. Be sure to choose Google from the range of calendar options.

This simple fix should solve any sync issues you were having and you’ll see all your events and data show up like usual. 

Reinstall Google Calendar

If you’re still having trouble though, you can try to reinstall the app:

  1. Uninstall Google Calendar by tapping on and holding the app icon until it starts to jiggle.

  2. Tap the “X” that shows up on the app icon to delete the app from your iOS device.

  3. Reinstall Google Calendar from the app store.

This fresh installation of Google Calendar should be free of sync issues.

How to Fix Google Calendar Sync Issues on an Android Device

Since Google Calendar is a native Android app, Android users have more tools at their disposal when trying to fix this problem.

Check If the Calendar App Is On

The first thing to do, as obvious as it may seem, is to check and make sure that Calendar is turned on. You may have accidentally turned it off at some point.

To check:

  1. Open Settings on your Android phone — not Google Settings.

  2. Select Apps or Apps and Notifications — whichever version applies.

  3. Choose App Info.

  4. Select More from the top right of the screen.

  5. Click Show System.

  6. Select Calendar Storage.

From this page, you should be able to see whether Calendar is turned on. 

If Calendar is turned on and you’re still experiencing sync issues, try a quick online search to see if the app is having an unusual problem. Often times, when a popular app like Google Calendar or Instagram experiences glitches or issues, a quick search will turn up news stories outlining the problem or cause, like wide scale maintenance or server issues. It may be that you simply have to wait for the app to come back online.

Check If the Calendar You Want to Sync Is Visible

It’s possible that the calendar you’re trying to sync wasn’t properly selected. Check which calendars your Android device is receiving information from Google Calendar. To do this, go into the app menu from the top left corner of the screen. You’ll see a list of calendars with labels such as, “birthdays,” “work,” and “important reminders,” as well as any custom calendars you may have created. Each calendar will have a checkbox next to it.

Check to see if the event you’re trying to sync and load on your device is part of a calendar with a checked box. For example, if you’re trying to find someone’s birthday:

  1. Find the calendar containing the event.

  2. Let’s say you discover you’ve added the event to a calendar named “birthdays.”

  3. Check to see if there’s a checkmark next to the “birthdays” calendar.

  4. If the calendar isn’t checked, just click the empty box to add a checkmark.

If you follow this procedure, the relevant calendar should sync to your device. In many cases, that’s all you’ll need to do to fix your problem.

This goes for any Android device experiencing sync issues. Always check to see if the device having problems is properly set up to sync with your Google Calendar. 

Check Your Data

If none of the above solutions worked for you, the problem could be your device’s storage capacity. Google Calendar events don’t take up a lot of space on your phone’s hard drive relative to data from other apps, but if your device is filled near to capacity, Google Calendar might have stopped syncing to keep that space free.

To test this theory, free up some storage on your hard drive. Clear out anything you don’t use or don’t need. Consider backing up and deleting non-essential data on your device as well:

  • Go through your camera roll and delete old photos or videos — or back them all up and wipe the slate clean. 

  • Scan for apps you never use that take up valuable space and delete them.

  • Try to clear caches for less frequently used applications on your phone.

To check if Google Calendar’s storage is turned on:

  1. Open Settings on your Android device — not Google Settings.

  2. Tap Apps or Apps and Notifications.

  3. Select App Info.

  4. On the top right, tap More.

  5. Choose Show System.

  6. Click on Calendar Storage.

This screen should give you some information about Google Calendar’s storage on your device.

If you can’t clear out old data or apps on your Android device, try deleting data from Google Calendar itself:

  1. Navigate to your device’s Settings menu.

  2. Choose Apps or Apps and Notifications.

  3. Select Google Calendar from your app list.

  4. Go to App Info.

  5. Select Clear Data.

To complete the process, turn your device off and back on again. 

Since this method deletes any data not already synced on another device for good, you should only consider this option as a last resort. Any events you lose by clearing Google Calendar’s data will have to be entered again manually. 

Give It Time

Your device could start syncing again in as little as a few minutes after trying these troubleshooting techniques. But be aware that it can take up to more than 24 hours before Google Calendar starts to sync up your data again. 

Restarting your device could help it begin syncing again more quickly. But if it doesn’t sync again right away, keep checking back and be patient. If the problem persists, report it to Google.
