How do I restore deleted iCal appointments or entries?

Hello gonzo80_19 ,

Thank you for using Apple Support Communities.

I understand from your post that a person you share a calendar with deleted many of your entries by mistake. I know how important it is for you to be able to restore your missing calendar entries. If the calendar was on iCloud, I recommend using iCloud.com to restore the calendar entries. The following article has the necessary steps and I have highlighted them for you below:

If you accidentally deleted your calendars, reminders, or contacts from iCloud

Restore your calendars and reminders from an earlier version

Several things happen when you restore an earlier version of your calendars and reminders:

• Your sharing settings get erased. You can share the calendars and reminders 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 and reminders:

1. Sign in to iCloud.com.
2. Click Settings.
3. Scroll down and click Restore Calendars and Reminders under Advanced.
4. Click Restore next to the date before you deleted your calendars and reminders.
5. Click Restore again to confirm. After the restore completes, you'll get a notification on iCloud.com and an email to the address on file with your Apple ID.

Best Regards
