If you want to try this yourself, try to build the interactive app above.

The WHITE text is output from the program. The YELLOW input is what the users types.

Be sure to try three cases:

• When your birthday is coming later this year
• On the day it is your birthday
• When your birthday has already occurred this year

Functions

def my_function(input1, input 2):
    line 1
    line 2
    line 3
    
    return value

Dates, times, and time spans

All of these come from the module datetime.

• datetime.date # actual date class
• datetime.timedelta # class for time spans
• The time right now is datetime.date.today()
• The difference between two dates is done via subtraction: delta = t1 - t0
• delta.days may be helpful ;)
