How to Write a Birthday Program

```

import datetime

Get the current date

today = datetime.date.today()

Get the user's birthday

birthday = input("What is your birthday? (MM/DD)")

Convert the user's birthday to a date object

birthday = datetime.datetime.strptime(birthday, '%m/%d').date()

Calculate the number of days until the user's birthday

days_until_birthday = (birthday - today).days

Print the number of days until the user's birthday

print("You have", days_until_birthday, "until your birthday")

```

If you want to add more advanced features to the birthday program, such as sending a birthday message or playing a song, you can use additional Python modules.
