How To Delete Multiple Calendar Events?

I recently got a Passport. I'm moving up from a BBOS device. I used BlackBerry Link to transfer my notes and other data to my Passport. My Facebook was synced to the native calendar app. However when they came over to my Passport, They were added in addition to the BB10 Facebook birthday reminders. So instead of 1000+ reminders, I now have 2000+. It's driving me cray cray. Anyone know how to remove them on my phone or computer?

Unfortunetly I don't beleive there is way to delete multiple entires manually, unless they are part of a series/recurring appointment.

That said, in your case you should be able to go to your facebook settings and just turn off the birthday toggle since you have your facebook birthday's in your calendar already from another source.
