Almost every iPhone user uses iCloud, which serves as a wireless private cloud space. With calendar syncing to iCloud, you should be able to check the iPhone calendar schedules on your Mac, iPad and any Apple devices that have synced into the same Apple ID. When the iPhone calendar failed to be synced to iCloud, you may not be able to see the calendar update on iCloud or Mac, or when you change a calendar on iCloud, the change doesn't show up on your iPhone. If you have a similar issue with the iPhone calendars, check the following tips.


Tip 1: Check iCloud account on your phone
Make sure that you have logged in your iCloud account to sync calendars from iPhone to iCloud. Also, your Mac should have been signed-in with the same account to sync iPhone calendars.


Tip 2: Check iCloud Calendars Settings
First of all, you need to make sure that iCloud Calendar syncing has been switched on. Go to Settings > iCloud and turn on Calendars. If it has been turned on, close it down and turn it on again.
