When you start using a new iPhone, one of the first thing you will do is connecting Facebook account to the phone. As I just want to use Facebook as news feed, I feel very annoyed when all Facebook friends’ contact information and birthdays are added to my Calendar app.
This could make a mess if you have a significant of friends on Facebook and you don’t care about their birthdays. The real appointments and events are much more important and absolutely you don’t want to miss them because of those birthdays.
The birthdays does not only show up in your Calendar app but also in the Notification Center. Therefore, most users will want to get rid of the birthdays from unknown friends. I will show you how to disable the feature on iPhone 5S or iOS 7.
To prevent Facebook birthdays from displaying in your Calendar, you just need to go to the app, tap the red Calendars text at the bottom of the screen. The text looks not to be clickable but it is, I hate the flat design more because of the confusion.
Subsequently, you will see the Birthdays under Facebook being checked. Now, just tap on the line to uncheck Facebook birthdays.
This will hide all birthdays of your Facebook friends in Calendar app as well as in Notification Center.
If you want to view birthday of your friend, you will need to look it up on contact page. Let me know if this post could help.
