     if day1_weekday == "Sunday":
         day1_weekday = 1
     if day1_weekday == "Monday":
         day1_weekday = 2
     if day1_weekday == "Tuesday":
         day1_weekday = 3
     if day1_weekday == "Wednesday":
         day1_weekday = 4
     if day1_weekday == "Thursday":
         day1_weekday = 5
     if day1_weekday == "Friday":
         day1_weekday = 6
     if day1_weekday == "Saturday":
         day1_weekday = 7
         
     days_difference = day2 - day1
     
     day2_weekday = (day1_weekday + days_difference - 1) % 7 + 1
 
     if day2_weekday == 1:
         print("Sunday")
     if day2_weekday == 2:
         print("Monday")
     if day2_weekday == 3:
         print("Tuesday")
     if day2_weekday == 4:
         print("Wednesday")
     if day2_weekday == 5:
         print("Thursday")
     if day2_weekday == 6:
         print("Friday")
     if day2_weekday == 7:
         print("Saturday")
