Birthday calendar bizarre repetitions and other issues

I have the STRANGEST things happening with birthdays on both my iPhone (5, 32GB, white, iOS 6) and iPad (32GB, iOS 6, white).


I'm posting it here in the iPhone forum, assuming more people may be able to help.



First of all, I sync a Google Apps calendar with my iPhone and iPad via CalDAV. I also sync my Google Contacts with my address book (including birthdays), which syncs via my MacBook on OS 10.6.8 using the sync icon in the system tray. (I hesitate to call it MobileMe, even though that's what the System Preferences calls it, because it really has nothing to do with MobileMe -- it does not sync via MobileMe [I do not have an account], it just syncs my Address Book with Google with my phone or iPad when hooked up. It is through a WIRED connection that it does the final sync to the device.)


So, my birthdays from my address/contact books and my Google contacts DO sync and they DO show up on both my iOS devices in the fancy Birthday calendar with the cute cake symbol, as well as in my Google calendar.



NOW HERE'S THE CRAZY PARTS.


  1. Sometime recently, my birthdays were getting repeated. But oddly, enough they are a different amount on the two iOS devices. I have 18 copies of all birthdays (on the same day) in my iPhone calendar and 68 (YES, SIXTY-EIGHT COPIES) in my iPad of every birthday.
  2. My Google calendar shows NO SUCH ERRONEOUS copies.
  3. The crazier thing is that the copies of the birthdays are NOT on the birthday calendar. In fact, IT'S AS IF THEY JUMP AROUND ON DIFFERENT CALENDARS. They show up all one color, but some random color. They will appear or disappear only SOMETIMES if I turn "off" some calendars or others (for example, once they would go away if I hid a "Personal" calendar, another if I hid a calendar I subscribe to via Google but sync via CalDAV from Weather Underground, and another calendar that is a Google calendar but also my "default calendar" in the iOS settings). And this is all within minutes.
  4. When I go into an instance of the repeated calendar event, it will actually say it belongs to my default calendar, regardless of what was hiding or showing it before.
  5. When I try to "edit" the birthday just to see what happens, it crashes the app.




WHAT. THE. ______???





Here's what already I've tried:


  1. Searching the internet for someone with a similar problem. NADA.
  2. Turning off the option to sync my Google birthday calendar via the Google sync page (I think it's actually unnecessary anyway, since iOS pulls from the contact book, anyway). That did nothing.
  3. Hiding all calendars and then selecting them to show one at a time to figure out which calendar was causing the problem, but as I mentioned above, it is not consistent.
  4. Re-syncing my devices with iTunes.
  5. Searching for and merging duplicate contacts in Google contacts.
  6. Turning off the iOS birthday calendar.
  7. Killing and re-starting the calendar app.
  8. Re-starting my iOS devices.
  9. Re-syncing my contact book with my devices.




Someone. Please. Tell me you're having this problem and that you have the solution? I'm going crazy over here! I can't remember anything that may have triggered this to happen.

I've deleted my Google account from my iPhone, iPad, iMac and MacBook. I've turned off Birthday calendar on everything.


Now I go to iCloud Calendar, on the web and I still have multiple birthday entries.


It looks like a bug in iCloud itself to me. ios 6 and Mountain Lion are just reflecting it.


I've just given up on using Birthdays until they fix it. Just part of a growing list of Apple doesn't work right anymore.

I don't think it's related to iCloud. I don't use iCloud for calendar, and I still have this issue. Most people in the other threads on the issue don't use iCloud either.

What I imagine could be in your case is that your iCloud calendar on the phone picks up all the "stray" calendar entries and syncs them into the cloud.

As you have noticed, deleting any or even all calendars doesn't help. These duplicate entries are stray, they don't belong to any calendar and thus can't be deleted by deleting / removing calendars. In one of the threads here there was a solution posted which was supposed to delete these stray entries too, but it didn't work for me. Only thing that does it is resetting the device to factory defaults and NOT restore from backup (the backup includes all stray events).

I had all the same problems and tried all suggestions but was not able to delete the recurring events until I found this post


http://productforums.google.com/d/msg/calendar/a7cGGdoL5GA/yZQ-7vdeodwJ


and the hint to iCloud (although I don't use it). So what I did - apart from all the other hints in this thread - was to remove all accounts (or at least all calendar syncs), and then sync to iCloud (actually first I removed the account, readded it and then turned on calendar sync). Then the multiple entries disappeared and I could reconnect all other accounts.


Hope this helps.

I have tried everything and have been unable to remove the duplicate birthday entries from my iPhone 5. If the native iPhone birthday calendar is enabled then I see multiple entries for every birthday. What's worse, each time the calendars refresh, another entry is created for the same birthday.


The only solution is to turn off the native iPhone birthday calendar and turn on the GMAIL calendar named "Contacts' birthdays and events (Read Only)".


I had this problem when I first got my iPhone and had to completely wipe it and start from scratch. Now, 6 months later, the problem is back. I also believe I know what causes the problem.


Old, working setup (calendars controled on each device):


Each calendar I want to sync is added as an account on my iPhone, or as a subscribed calendar. E.g. tripit, Holidays, sports calendars, google calendar, etc... Running the calendar app, going to "calendars" then checking each one on, including the "Birthdays" calendar, works fine.


This was a headache because I effectively did the same thing in google calendars on my laptop, subscribing to each calendar. I had the identical setup in two places. So, I decided to do it the "right" way.



Broken setup (calendars controlled by google):


I removed all calendars from my iPhone by turning off google calendars in settings/accounts. I confirmed that all of my calendars were properly configured in google.com/calendar. Then I went to this URL:


https://www.google.com/calendar/syncselect


and enabled all of the calendars, including "Contacts' birthdays and events (Read Only)"


I then re-enable google calendars on the iPhone. Now, all of the calendars are listed in the calendars app under the account "google".


This is when all of the birthdays in the iPhone native birthday calendar (the one with the birthday cake) started multiplying.


At this point I found no way to remove these multiple entries, even though I have tried everything everyone has posted here. The only fix is to turn off the iPhone native birthday calendar. The google one is better anyway. 🙂



Even if I remove the google account completely and use only the native iPhone calendar, the duplicate birthday entries still exist.

I was able to finally get rid of the duplicate Birthday calendars the following way.


1. Turn off all calendars on your iOS device in Settings > Mail, Contacts, Calendars

2. Create a complete backup of your iOS device on your computer with iTunes.

3. Make a copy of the backup folder

4. Download and install iBackupbot on your computer

5. Delete the Calendar folder and all Calendar items out of the backup as shown in the screenshots.

6. Reset your iOS device and use the edited backup to restore it.

I fixed it on my iPhone 6s.


Open your Apple calendar. At the bottom in the middle there is the word "Calendars". Click on it and scroll down until you see the "Facebook" list. I had about 12 listings for "Birthdays" and they were all checked. I unchecked all except one.


Below that is a section entitled "Other" which had a bunch more of the checked birthday list. I unchecked all but one on there.


When I went back to my calendar there was only one birthday per person. I hope this works for everybody
