Duplicate Birthdays in Calendar

I have an issue of when the Birthday Calendar is activated, birthdays are showing up multiple times. The only account I use for my calendar is my work Exchange Account. When I deactive that account, they go away. However, doesn't seem to be a problem in Outlook on my office computer, and my contacts are fine. Not sure why Apple is multiplying the birthdays. So it seems the problem stems from how Calendar is pulling in Birthdays from my Exchange contacts.
I even removed my Exchange account completely from my Mac and readded it hoping it would redownload everything and fix the problem. It still did it.
Thoughts?

I just had the same problem - my calendar was showing multiple birthdays from my contacts. It happened after migrating from my laptop to my new desktop iMac. Everything was fine on the laptop but not on the desktop. I backed up my contacts on the new iMac following some advice in a different discussion on this site and then I deleted (yes, deleted) all my contacts, both from 'on my mac' and from icloud. Luckily, when I re-imported the contacts, they were copied into contacts on my mac and from there I dragged each group into icloud. I then rebooted and it worked. No more birthday duplications!

How can I get rid of duplicate birthdays in icloud Calendar, especially when there are no Contacts in the iCloud? Case ID: 365381395

How can I get rid of duplicate birthdays in icloud Calendar, especially when there are no Contacts in the iCloud? Case ID: 365381395

Found the answer myself while helping to set up iPhone. It is simple when you know how. Before signing out of iCloud to sign in again and restore the link to Photo Stream I had opted to copy iCloud contacts to the Mac. When I signed in again this created two iCloud views which can be seen in Contacts Preferences. I just disabled one of them. Not brave enough to attempt removal but I gues this would work too.

Duplicate Birthday Calendars

My iphone duplicates the birthday entries on the calendar. The iPhone info tab in iTunes seems to have the option to synch Birthdays from the calendar even after i deselect all options to synch birthdays. *Is there a way to delete the Birthdays option from the iTunes:iPhone:info tab?* If I select the synch Birthdays tab, it puts the Birthdays Calendar on my iphone, but not on my iCal. If I choose to synch Birthdays in iCal I have it on iCal and on the iPhone. There are then two "Birthdays" options to select from the iTunes:iPhone:info tab.

That solution didn't solve the problem for me. I too had Birthdays showing up twice in the "Sync... Selected Calendars" list. What worked for me was disabling syncing of all info in iTunes and .Mac sync, quitting all applications and deleting the following folders:
~/Library/Application Support/MobileSync/
~/Library/Application Support/SyncServices/
The tilde character (~) signifies your user account's home folder. Once I did that, I attempted to resync the info with the iPhone, but I found the contacts, calendars and Mail accounts lists empty as though there was nothing to sync with. So I opened Address Book and tried to sync again and suddenly all the contact groups appeared in the list. Launched iCal and tried to sync again and suddenly all the calendars appeared. Same thing with the mail accounts. Not sure if launching the seperate apps was necessary, iTunes may just have needed a bit of time to rebuild the links to the application data. Everything is working fine again and this time, I don't have duplicate Birthday calendars.
Just as a side note, those folders I deleted I believe contain cached information related to synchronization, and I believe the problem stemmed from corrupt or duplicate information which was resolved by deleting them and forcing iTunes/.mac/Sync Services to rebuild them. There is no important data stored in either folder that won't get recreated by the apps in question, although it's probably a good idea that you do a complete sync of both .mac and your iPods/iPhone before deleting them. In my case, the Mac I was using contained the 'master' databases for all apps, so I didn't hesitate to tell .mac to replace it's contents with the information on my Mac. Proceed with caution if you have multiple Macs that may not be in sync with each other.

How to Delete Duplicate Birthdays in iCloud?

While the birthdays are shown properly on my iPhone, there are duplicate records in iCloud. I guess this might be due to revisions to the contact information, or synchronization of two (or even more) sets of contact information with iCloud by mistake. For the latter, I have already removed the duplicate set of contact information from both my iPhone and iCloud. However, there are still duplicate birthday records in iCloud as shown in the attached picture. When I attempted to delete the duplicate birthdays, a message saying that this is a read-only information and can't be edited would display.
I should be grateful for other users' advice on how to resolve the problem. Advice on how to distinguish which of the duplicate records is associated with the existing contact and hence should be retained, and which is/are associated with old records and can be deleted would also be highly appreciated. Thank you very much.

Hey fchengwy,
Thanks for the question. I understand you are having issues with your Birthday calendar in iCloud, specifically duplicate events. The following article addresses Birthday calendar troubleshooting, and steps to resolve any duplicate entries:
iCloud: Advanced Calendar and iCal troubleshooting
http://support.apple.com/kb/TS4337
To clean up issues related to manually adding birthdays to a calendar in Calendar (or iCal):
1. If you already have the Birthdays Calendar enabled, deselect it in the Calendars list in Calendar (or iCal).
2. Search Calendar (or iCal) by entering "birthday" (without the quotes) in the Search dialog in the top-right corner of the Calendar (or iCal) window.
3. Sort the Search results by title, so they are easier to analyze.
4. Locate any birthdays that are returned in the Search results that are not contained in a Holidays Calendar (such as John F. Kennedy's Birthday, Lincoln's Birthday, and so on).
5. For each non-Holidays birthday returned, decide if you want to keep it. If so, open Contacts (or Address Book) and verify that you have a Contact for the individual. Enter the birthday information for that person in Contacts (or Address Book). For more information about updating Contacts (or Address Book) fields, see this article.
6. After verifying that the birthday is entered in Contacts (or Address Book), remove any birthday events not stored in the Birthdays or Holidays calendars by selecting them and choosing Delete from the Edit menu.
Note: You can select consecutive items by holding down the Shift key while selecting them. You can select non-consecutive items by holding down the Command key while selecting them.
After cleaning up any manually added birthdays, you can enable or re-enable the Birthdays Calendar. To enable the Birthdays Calendar for the first time, open Calendar (or iCal) > Preferences and select the checkbox next to Show Birthday's Calendar. If you temporarily hid the Birthdays Calendar as per the instructions above, you can re-enable it by selecting the checkbox for it in the Calendar List.
Thanks,
Matt M.

Duplicate birthday in my iphone which not in my icloud

Duplicate birthday subscriptions

I recently upgraded to Mountain Lion. While on Lion, I started using iCloud for the Contacts and Calendar and things seemed to work properly after this. A few of my calendar entries have birthdays and I had subscribed in Calendar to Birthdays. That too seemed to work normally. After upgrading to Mountain Lion, these birthdays show up in duplicate on the Calendar. Apparently, I still have Contacts entries both in iCloud and On My Mac. These show up as "linked cards". Contacts seems to resolve the duplicate entries so they show up as one contact, but Calendar does not do this properly and they show up as duplicate birthdays. Any suggestions other than deleting the On My Mac entry for these contacts?

OK, I deleted the On My Mac and kept just the iCloud contacts. That worked kinda, except that I just had "birthday" listed for the deleted contacts that were on my Mac along with the another entry with that person's name and "Birthday". So I deleted contacts, reinstalled them from iCloud, and then just had "birthday" listed twice on those dates for where the birthday listings used to be, no names.
I deleted the Birthday's subscription, and added it back in. Now I have no birthdays showing up, even though they're back in Contacts.
Sigh.

HT204150 duplicate birthdays appear in iCal on my MacPro?

I have duplicate birthdays appearing on my Mac in iCal. The first one has the name, the second just had 'Birthday' beside the present icon. So every birthday in my contacts is displayed with this extra icon.

Hi,
I couldn't import ics invitation received by email (in Mail). When I clicked on the ics invitation iCal was opening buy the ics invitation didn't appear.
Reading a few post I realized I could drag the ics invitation from from to iCal and then the invitation appeared into the "Waiting to confirm box" - on the right of the calendar button. By default is tried to sync using the "on my mac" account.
ANSWER:
I wasn't using this account, so I DELETED all my "on my mac" calendars and iCloud calendar is now my default. From now on all my ics invitation are imported into iCal AND they sync flawlessly to my other device (iPhone 5 and iPad 4) and to people sharing this calendar.
MacBook Pro (Retina, Mid 2012)

I create a birthday calendar in iCal and then click on it in iphoto at the begining of the calendar project each year. Some how the birthday did not populate the photo calendar. Is there a way to add the birthday iCal calendar into the calendar project?

I created a birthday calendar to use in iphoto for calendar. When a new calendar project is started each year, I click on it in. Some how the birthday did not populate the photo calendar this year. The photo calendar is almost complete. Is there a way to add the birthday iCal calendar into the calendar project? I would prefer not to start over.

Hi,
If you first select the calendar on the left, so that its background is highlighted blue/grey, when you make a new events they should be added to that calendar.
Best wishes

How to hide birthdays in Calendar except important ones ?

Is it possible to hide most birthdays in Calendar, except a few, i.e., those of the VIP's, for instance, the spouse? ;-)
I don't want to delete all the birthdays from AdressBook, but I'd like to see in Calendar only those that are really important.
And, if possible, I'd like to get a reminder only for those.
All hints and pointers will be highly appreciated.
Best,
Gabriel.

No, I meant disable the built-in Birthdays calendar and create your own. There is a preference to display the Birthdays calendar. Turn it off, create a new calendar, and add all the Birthdays you want to know about.

Can you edit or add a custom event to contacts to show in Birthday Subscription calendar

I want to modfy Birthday subscription calendar to include custom events that appear in my Contacts. Is there a way to do this?
Or how can I create a new subscription calendar to be published in my iCloud acct pulling the custom events from Contacts?

You have some contacts with more than one birthday?
To add a custom label for a date, select Edit for an existing contact. Select Add Field. Select Date. Scroll up with the Info window above the date selection and select Other for the new date selection. Select Add Custom Label and then select this label for the new date field for the contact.
As far as linking dates with multiple contacts, the answer is no to that.

Siri duplicate entries in calendar reminders

I had some trouble with duplicate calendar entries in Calendar with iCloud and Siri, showing duplicate entries in my iPhone, but not on my macbook pro. I've now set the iphone to show just iCloud entries, which seems to have fixed duplicate entries in Calendar, but when I ask Siri what I'm doing today or if I slide down the quick view, it shows some of my entries twice - how do I delete duplicate entries there if Calendar is only showing the iCloud calendars?
Before I changed the settings, iCloud tried to sync 7 calendars -
Yahoo (I forgot I even had this one)
home .mac
work .mac
home itunes account
work itunes account
icloud home
icloud work
iCloud Calendar (not sure why it has this one too)
In Calendar it now just shows -
iCloud home
iCloud work
I unticked iCloud Calendar but it still shows duplicates when I ask Siri 'what am I doing on XX'. I can't find a setting to change it.

HI - hope you can help. I have just eceived my 4S and I too see that Siri finds duplicate calendar entries for every meeting. This does not show in the nomral calendar - only when Siri searches. Before I do as you did - turn of calendar syncing - did you find that your calandars (I have 17) still kept up to date with iCloud? Thanks for your help. SM

Why are there duplicates in my calendar?, why are there duplicates in my calendar?

Why are there duplicates in my calendar?

Is it possible that you or someone copied them to that folder or an automated progress making a backup to that folder. Normally if you upload the photos then will be stored in your iPhoto library folder.

Remove duplicate holidays from calendar mac

How do I remove duplicate holidays from calendar mac. I have iCloud and I have read that may be part of the problem, but I need help to remove duplicate holidays from calendar mac.
Thanks

If you have iCloud and another account like Gmail, you could be seeing holdays for each account. You need to deselect one of the holiday calendars.
Do you see Holidays in the sidebar where Calendars are listed? If yes, uncheck.

How to not create duplicates in contacts & calendar on laptop #2

Ok. I have 2 laptops and someone how here helped me solve the duplicates issues on laptop #1 - it was only happening on the calendar side. Now i need to synch the same BB on a dif laptop.
I thougth I solved it when on laptop #1 the config is set that outlook always wins and on the desk top manaager on laptopo #2 I set it to say BB always wins. That said, when I synch bb w/ laptop #2 I get duplicate contacts and calendar.
Now that laptop #1 is almost solved what if I wipe out the PST folders on laptop #2 re- transfer the PST from laptop #1 and then synch?
Although I did that and I still get duplicates.
Then after laptop #2 messes up the bB the BB duplicates laptop #1 again. Obviously I can stop 1/2 the insanity but the objecitve is to have laptop #2 mirror laptop #
Thansk in advance muchly! M33climb

So a strange thing happened actually, I did like I explained previously and nothing happened but when I wrote an expression like (ID == 0?"ALLDAY":'ALLDAY') - where ID is just a PK property in the EO it worked. Practically it is the same thing but who knows, at least now it works.
