如何根据 Python 中的输入找出自定义日期（日历格式）？

Question

My problem sounds like this: For N people, input their names and birthday dates. Based on this information, using substitute, create a custom message like: "Hey... . There are.., more days until your birthday. when you will turn... years old: A trip awaits you in the following days. ... -.., ( the period has to start 3 days before the birthday. and end 3 days after.)

For example: n = 1 Steve Potter 02.07.2000

output: Hey Steve Potter, There are 31 more days until your birthday, when you will turn 20 years old: A trip awaits you in the following days. 29.06.2020 - 05.07.2020

So far, I can't figure out more than that:

import string
import time

invitation = string.Template("Hey $name , There are $nrdays days until your birthday, when you will turn $years old. A trip awaits you in the following days: $start - $end")

n = int(input("Number of people:"))

for i in range(0, n):
    i_name = input("Name of the guest?")
    i_data = input("Birthday?")
    data = time.localtime()
    i_bdday = int(i_data[0] + i_data[1] )
    i_bdmonth = int(i_data[3] + i_data[4] )
    i_bdyear = int(i_data[6] + i_data[7] + i_data[8] + i_data[9] )
    i_years = data[0] - i_bdyear
    print ( invitation.substitute(name = i_name , years = i_years) )

How can I figure out how more days are there until a given date and also the interval I need? Thank you
