Automatic reminder for birthdays as well as exportation to google calendar?

Automatic reminder for birthdays as well as exportation to google calendar?

I just imported my contact information and would like have reminders set for all their birthdays.  I can do this manually by creating an event, setting it to remind me three days in advance and then saving and exporting it to my google calendar.  However, I have over 1000 contacts and this would take some time.  I'm wondering if there is a way to automate this process?  Or at least have the date of birth automatically exported to google calendar.  I appreciate your help!
