My contacts that I have addedin last two years and all my calendar events have disappeared. I tried to download a backup from icloud.com and used the one from May 9th. Still no luck. How do I get my calendar back and why did this happen? I have always backed everything up to icloud. Interesting enpough my daughter has the same problem. Different Apple ID. We do share a domain email address for our work. Could that email being hacked mess with our contacts?

Contacts and calendar aren't part of the backup, since they are synced to whatever cloud or mail program you use.

If you synced to icloud then look here Use iCloud.com to restore and recover iCloud information - Apple Support

if you synced with your mail account, contact your mail provider on how to recover the data.
