How do I remove Facebook birthdays from my windows 8 calendar?

Hi MelanieAynat,

Thank you for posting your query in Microsoft Community.

As I understand that you want to remove Facebook birthdays from my windows 8 calendar.

I believe your Facebook account is linked to your Hotmail account so after configuring the account to Calendar app, all birthdays are synced. You cannot remove these events by manually deleting them since these are downloaded and synced from your Hotmail account, what you can do is remove your Facebook account from your Hotmail to totally remove them. Here's how:

1. Sign in to Windows Live Profile page: http://profile.live.com/services

2. Click Facebook, click Remove this connection completely.

3. Click Remove button in confirmation window.

But if you still want to have your accounts connected, please note that all events that are from both accounts will be in the Calendar App.

Please perform these recommended steps, review the additional information provided and post back if you are still experience the issue. I will be glad to provide you with additional options available that you can utilize to get this resolved.
