I can tell you from experience, I filled out the online support form and Apple called within minutes. I told the tech what was going on, and he promoted the to an engineer who then called me. Within about 2 weeks, if I remember correctly, all was well and everything was back to normal. So I assume someone has to manually go in there and clean it up. I can tell you that my issue was related to Windows Live contact syning because the contact's birthdays were 1 day off of their actual birthday and that is a known bug. After I stopped syncing the Live contacts, the duplicates remained.
Go fill out the online support form and see what they can do for you personally.

I would have though with the amount of people that experience this Apple would be able to help quicker when someone else contacts them. From my experience the support treat this is a new case each time and spend way too long tyring to fiddle with your devices then correct the source of the problem in iCloud. I'm on the phone now, which would mean a total of 3 hours of support to fix their server issue. I'm very tempted to export my contacts/calendar and go back to gMail

The guy from Apple engineering has setup diagnostic mode (reset password, give them access to your account etc). I guess they need to manualy reset the birthday calendar - or whatever they do. It's a pity Apple can't put a reset on the calendar for us to use or wipe the birthday calendar cache when you untick show birthdays calendar.

The problem is that "birthdays" come from your contacts no matter where your contacts come from. I had no problem for 3 years using iCloud contacts, but for some reason I wanted to test Live contacts syning. So I did that, and there were duplicate birthdays for each contact, but each date was off by 1 day, which is a known bug in iOS.
After I removed syning, the birthdays ONLY stayed through iCloud and NOT my device, so it wasn't that big of an issue. It just annoyed me through the web interface.
I agree this should not happen at all, but since it does there should be a simple solution such as turning off then on the birthdays calendar.

I've fixed my issue sometime ago, do not remember exactly how, and now my contacts are properly represented in iCloud with their birthdays updated. Of course, after that, I was afraid to use Facebook integration and plan to do "in the future" (or never).
What probably is needed are simple "utility functions" that allows oneself to just rebuild everything. In general, if you disconnect iCloud, re-state the content locally and then re-connect & rebuild you are able to recover everything and from that point all works. Last point: having a good backup is essential.
When one contemplates "from the top" all this "iCloud not working issue" one understand why S.Jobs wanted to buy Dropbox -> Dropbox works simply better than iCloud.
