If you are attempting to sync Calendars with WiFi, or USB, try: iOS: Syncing with iTunes.
If you are using iCloud, try iCloud: Troubleshooting iCloud Calendar.OS X Mountain Lion, iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle

I have tried this many times as well. Calendar sync is flat our not working with the USB method either for Outlook 2011 or iCal. This previously worked but when ios went through the last two revisions all stopped. An iPhone without calendar sync is just about usless.
I really can't believe Apple can allow this to continue. Very frustrating.
