In the response of a reddit comment, I changed few parts of the code:

1. now it can handle multiple birthdays on the same day
2. removed the exception handling part of code

hey just a quick note:

If you want to deploy your your app on online servers so that it can run everyday and check for birthdays, you are most welcome BUT before that make sure you put your email address and passw into the environment variables

Don't expose it in the code

Happy Coding...
