If you have the user-entered date in a string format, you can use
datetime.strptime() to convert it into a datetime object, like so:

    from datetime import datetime
    user_date = datetime.strptime(user_input, "%m/%d/%y")

Get the current system date like this:

    now_date = datetime.now()

Subtract the two datetime objects to obtain a timedelta object:

    mydelta = now_date - user_date

Look at the days attribute to get the difference in days:

   mydelta.days
