You may use CRON and the Notification API of facebook.

1. First you need to store the id and the extended access token of the user in your database.
2. Then, run your scheduler and fetch the friends' birthday of each user using the user's token
3. Send the notification to the user using notification API (just requires the APP access token - which you can obtain from here )
