Delete birthday calendar iphone

My calendar display screens birthdays for people with whom I am not much longer connected. I have actually gone so much as to attempt to disable the BIRTHDAY calendar altogether, however I still view these people"s birthdays showing up in my calendar. These human being are no much longer in my contacts, and I deleted my Facebook account, so I do not know why (or how) calendar would still be syncing with my FB contacts. I"m so confused!

Thanks in development.

You may have conserved their birthday in their call card. Try deleting their number from your phone book (anyway you are no much longer associated through them
