I had exactly the same problem with my iPhone. Unfortunately I had not made any backups in iTunes or iCloud and I lost all my calendar events. I called Apple tech support and they said I should have made backups. The unfortunate thing is that when iPhone prompted me for the update, there was no warning that this could happen or that I should back up my phone! E.g. Windows always warns you before these kinds of critical installataions to back up the data.

I had the same problem. If you go to Settings > General > Mail, Contacts, Calendars... Down toward the bottom it asks how long you would like to syncs events for. Mine was set to one month back. Set it to "All Events" and everything should come back shortly. At least it did for me. Hope this helps!

I had the same problem with my iphone 4S, but I don't have a menu item BKesley4 mentioned. My solution was:
To sync your calendars using iTunes:
- With iTunes open, connect your iPhone or iPod to your computer.
- Click the Info tab (or the Contacts tab)
- Click on Sync Calendars checkbox if it's not checked in
- Uncheck "Do not sync events older than x days"
- Click Apply
