Restore calendar
iPad Pro - iOS 12.4 - calendar and all events disappeared. How can I restore?
Hi Skyhawk65,
May I know did you make a backup of your iPad previously?
If you did, did you backup using iCloud or iTunes?
If you backup using iCloud, u can restore your calendar using iCloud.
Similarly if you backup using iTunes, u can restore your calendar using iTunes.
You can refer to this link: https://support.apple.com/en-sg/HT204184, it covers restoration from iCloud backup or iTunes backup.
If you did not do any backup, I think you have to recreate your calendar from scratch.
Hope these helps.
