Q: can't see Facebook events in the Calendar

It's crazy! Some facebook events I've been invited to are showing up, as are all birthdays.

But not the one's I'm hosting that I created as an event. I don't want to have to enter all that data once in facebook and then again in my calendar.

Help!

I do have the same issue without. Every single event on my Facebook account is not showing in my calendar both on my iPad and iPhone. I tried to use my friend's Facebook account and the events do show up as they should. I believe this might has something to do with Facebook account itself.

Yep, same deal here. I can't see any facebook events or birthdays even though it looks like everything is set up properly in iOS.

I'm having the same problem.  It doesn't seem to matter if the FB event is public or private.  Stuff just isn't showing up at all anymore.  It used to work.  Maybe FB changed privacy settings system-wide or something?

The failure of this feature along with maps and other leeser bugs makes me feel that iOS6 was a rush job that wasn't properly tested.  I think the iPhone 5 release date constrained them.  I hope they get their act together and release an update soon!

I'm having the same problem. A few notes in case this might jog someone into realizing what's going on.

I removed all the Facebook apps on my phone, disabled all of the facebook integration settings, rebooted it, and started from scratch ... multiple times. Even disabled the other calendar sources I have. (Google and work CalDav.) No luck.

If I go into Settings-->Facebook, turn on Contacts integration, and go back to the Calendar.app I can enable Facebook Birthdays and they come across fine. You would think that the iOS to Facebook authorization is handled in one spot but perhaps that isn't the case.

I've looked up and down the Facebook settings via the web site and the iPhone app. Nothing looks amiss. (See previous comment about authorization.)

I have, for lack of better words, messed around heavily with my iPhone Calendar and Contacts settings. I started with syncing with Google contacts and Googe Cal over the net directly, then moving to CalDAV and CardDAV, for both. At various times I messed with iCloud sync as well and adding the same Google services to my Mac laptop Calendar and Contacts app. Currently, I'm back to Google for CalDav and CardDav over the net on the iPhone and the Mac. Everything works pretty well except some Contact fields don't line up, which usually isn't a problem and, of course, Facebook events no longer show.

Why do I mention all that? Perhaps some of you have tried similar things and we've corrupted one of the internal settings files or plist and put our phones into an unrecoverable state. I can't recall when the Facebook events stopped showing after I messed with things because ...

The events stopped syncing but some of the old ones were around for a bit. They all dissapered once I started trying to fix it but it wasn't like they were all gone one day. When I noticed this problem it was because events I were adding stopped showing up but there were still a few listed. Almost as if the sync stopped kicking in but the events themselves were still cached.

Anyway ... that's probably tl;dr length but hopefully it will jog some brain cells.

Feb 2013: it looks like there is a bug currently preventing Facebook events from syncing to iPhone, even though Facebook birthdays appear to be unaffected.

Although the Facebook Events calendar appears ticked under the calendar list and access to the iPhone calendar is switched to 'On' under Settings>Facebook, the events are currently not syncing across (i.e. the usual Facebook banner for each event with a solid or dotted line depending on the acceptance status does not display).

The only workaround I have found is to subscribe manually to the events calendar, following the instructions at this page: http://www.hongkiat.com/blog/sync-birthday-event-iphone-cal/

Hopefully Apple will resolve this problem asap.

I have no idea what is going on but now Facebook events show up on my calendar app as they should.

I have been using the method Giacomo89 described as a temporary solution for a while. Recently, I just become playful and try to enable the Facebook event sync again. And as you might know it just work! Problem solved but mystery remains.

Sorry I'm ignorant about how Apple tracks bugs publically, or whether it even does, but is there some way to check the status of this?

Giacomo89, how did you find out it is a known bug? Thanks!

Facebook events just started working again on my calendar a few days ago. Can't say exactly when but I certainly didn't do anything to make them pop-up. Just noticed they were there all of a sudden.

Go figure......

... and now it stopped again. It's really bizzare.
