How to stop iOS from showing tomorrow's birthdays everyday My iPhone, for some reason (I haven't set up anything like that), shows the next day's birthdays everyday at 12:00 (at noon). How do I prevent that? I don't want to remove them from calendar, I just want to remove those annoying notifications.

(Default Alert Times for Birthdays is already set to "None")
iOS Calendar: Go to

preferences / mail, contacts &amp; calendar / calendar / default alert times / birthdays 

and select none. That should prevent your iOS calendar from
notify you whenever there is a birthday in your calendar.
Facebook: Maybe these notifications are from your Facebook app. Try turning these notifications off.
