Restore your calendars from an earlier version 

Several things happen when you restore an earlier version of your calendars. 

* Your sharing settings get erased. You can share the calendars again, or you can ask the owner to share them again.

* iCloud cancels and recreates all of your upcoming, scheduled events, then resends the invitations for you.

To restore your missing calendars: 

1. Sign in to iCloud.com.

2. Scroll down to the bottom of the window, then select Data Recovery.

3. Select Restore Calendars. 

4. Select Restore next to the date before you deleted the content.

5. Select Restore again to confirm. After the restore completes, you get a notification on iCloud.com and an email at the address on file with your Apple ID.

If you were not syncing your calendars with iCloud and the event was accidentally deleted, you can try to re-create that event: Create and edit events in Calendar on iPhone - Apple Support

Thank you for using Apple Support Communities. Take care.
