Previously, the “Birthday” calendar was an additional calendar which you had to manually add to have it displayed in your calendar. However, a recent update by Google seems to push the “Birthday” calendar to the main calendar app and there is no way to disable it. For those who are not aware, the “Birthday” calendar grabs the birthdays of all your contacts, including Google+ contacts, and displays them on your calendar. For those who want to get the Google+ Birthdays off their calendar, here is a workaround:
Go to your G+ page and click on the “Settings” option under the “Home” dropdown.
Scroll down until you see the “Your Circles” section and click the “Customise” button.
Now, uncheck the box beside the circle of the contacts whose birthdays you don’t want to see on your calendar. This also means that when you share posts, photos, profile data and other things with “Your circles,” they won’t see it.
Click “Save.” Now refresh your calendar app. You will find that the Google+ Birthdays will no longer be there, except for those in the circles that you have selected. As mentioned above, this is a workaround rather than a fix to the issue. Until Google provides the option to disable it, this is the only way to prevent Google+ Birthdays from showing up in your calendar. Let us know if this is useful to you. Update: To remove the Google+ birthdays from your Android phone, you first have to open the G+ app, make sure you are sign in, and get it to refresh. This will make sure it syncs with the settings you configure on your desktop. Lastly, run the Google sync and all the Google+ birthdays will be removed from your mobile calendar.
