how to send automatically send push notification for Birth Day wishes to the users based their Birth Day
Any help appreciated
Thanks

You need to develop a script (eg: in PHP) that gets all the users celebrating the anniversary today from your DB and send a PUSH notification to them.
Then, run this script once a day, using a cron.

The technical details of how to do this will depend on each case.

I can not help you anymore.
