Is there any way of adjusting the reminder generated in the contact birthdays calendar? Since the calendar is read only, my option is to enable or disable all reminders. I don’t need reminders for everyone I have a birthdate for and some I’d like a bit more notice. I can’t find any way to adjust either in the calendar settings or the contact itself and it seems a waste to have to recreate events for birthdays I want to remember.
AFAIK this is not possible right now.
