How do you remove Facebook birthday from "My Calendars"? My calendar is full of facebook friend birthdays! and worse, they are listed under "My Calendar", not Facebook calendar, so I can't hide them by unchecking Facebook in Calendar, Settings > Calendars. Even thouh they are listed under My Calendar, they still have facebook logos on the entry and a sync logo. I tried by turning off the sync option, but they are still there. How can I remove them from my calendars, and add them to the "facebook" calendar?
This was reported in the Android Central forum here with a link to LifeHacker. It sounds like it will allow you to sync your Facbook calendar without the birthdays because you're exporting the events directly from Facebook. First, you may want to undo the sync that you have going on now. Hope it helps.

Quoting the post from Android Central:


  just go to your google
  calendar thats linked with your google
  account on your phone and then follow
  this article.
  
  Add Your Facebook Events to Google
  Calendar
  
  
  In Facebook, go to your EVENTS page.
  At the top of that page click EXPORT EVENTS
  You'll get a pop up window with a URL, copy it.
  In Google Cal, on the bottom left you'll see ‘Other Calendars' and below
  that a link to ADD. Click ADD
  One of the new options you'll be presented with is ADD BY URL, select
  that
  Paste the URL from Facebook where it asks for it.
  
  
  and thats it! when your phone calendar
  syncs with your google calendar, all
  your facebook events will show up too
  and no birthdays.
