If your iPhone Calendar deleted events, here's how to get them back.

Open the Settings app.
Tap Apps.
Tap Calendar.
Tap Sync.
Tap All Events to sync every calendar event; choose a shorter length of time if you don't want to sync your oldest events.
Now exit Settings and open the Calendar app.
Tap the Calendar icon.
Drag three fingers down from the top of the screen to refresh your Calendars; you'll see a buffering symbol at the top while your events refresh. I did this while my iPhone was connected to my home Wi-Fi, and my events refreshed in just a few seconds. If your connection is slower, it may take longer.

That's it! The missing and deleted Calendar events from past calendars should be recovered. If you're having trouble syncing your iPhone Calendar, make sure to check out our troubleshooting article. For more great Calendar app tutorials, check out our free Tip of the Day.
