Facebook/calander help

My pearl has the facebook app and ive synced it with my calander. Whenever its one of my facebook friends birthday it lets me know at 23:45 the day before. I was wondering if there is a way i can change it to a different time? Ive looked through the options and couldnt find anything!

go to the calender and change the time of the reminder??

there isnt a way of doing that

It notifys you at that time because your reminder for the invitation is set for 15 mins before. if you go to the bday and select the series you can change the reminder time
