Generally speaking, if you log in the same Apple ID, then go to iCloud to enable calendar sync, calendar items on all iOS devices would be synced via iCloud. However, issues like iPhone calendar not syncing or iPad calendar not syncing occur from time to time. Here in this post, we summarized a few possible ways for you to fix iPhone calendar not syncing or iPad calendar not syncing issue.

Method 1. Reboot iPhone/iPad

No matter what issue you are encountering, rebooting iPhone/iPad is always helpful.

To reboot iPhone/iPad, you just need to hold the Power button and Home button simultaneously for a few seconds, the iPhone/iPad would start itself. For iPhone 7, you should press the Power button and Volume Down button instead.

Method 2. Turn Off Calendar Sync then Enable it Again

To fix calendar not syncing on iPhone issue, go to Settings > [your name] > iCloud, switch the tab beside the Calendar to your left to disable calendar sync. A few minutes later, go to Settings > [your name] > iCloud again, switch the tab next to Calendar to your right, calendar sync is enabled again.

Please be aware that even after enabling calendar sync again, you may still need to wait a few while before all calendar items can be synced to all iOS devices. Just wait a few minutes to see if all calendar events have been synced.

Method 3. Change Calendar Settings

The most likely reason why iPhone calendar not syncing or iPad calendar not syncing calendars on an iOS device is set to only sync calendars in a very short period of time. To change this, you can go to Settings > Calendar. We suggest you choose Sync All.
