I've seen a lot of questions around how to manage birthdays and created automated birthday e-mails. Are any of you still looking for a solution? I have found it, tested it, and it works! You'll need to use Zapier for the date processing logic but my solution can help you get this done. It solves for any number of input formats, leap year, and the incrementing of birthdays from yea to year.
