So I had the same problem and I found a solution that worked for me. Navigate to:
Settings > Mail, Contacts, Calendar > (Under Calendar) Sync then select "All Events".
So I guess in my case I was connected to iClud except it was not syncing my old events. Hopefully your problem is fixed!

I think this happened the last time the clocks changed. I have just turned calendars off did a soft reset on the phone turned it on, put icloud calendars back on, did an icloud update and all is good. Thanks to the previous posters for reminding me

Bluetooth has to be on for icloud to sync. Make sure Bluetooth is on on both devices that you're trying to sync. Had the same issue and just figured this out!
