Answer :-

d = {"Sunday":1,"Monday":2,"Tuesday":3,"Wednesday":4,"Thursday":5,"Friday":6,"Saturday":7}
days = { 1 :"Sunday",2:"Monday",3:"Tuesday",4:"Wednesday",5:"Thursday",6:"Friday",7:"Saturday"}
dic= { }
user = int(input("Enter a number between 2 to 365 = "))
day = input("Enter first day of year (Sunday, Monday, Tuesday,Wednesday,Thursday,Friday,Saturday)")
first = d[day]
for j in range(1,366) :
        dic[ j ] = first
        if first == 7 :
            first = 0
        first += 1
a = dic[ user ]
print()
print(days [ a ])

Output :-

Enter a number between 2 to 365 = 56
Enter first day of year (Sunday, Monday, Tuesday,Wednesday,Thursday,Friday,Saturday)Friday

Thursday
>>> 

Enter a number between 2 to 365 = 100

    #It can be done more easily
    day=input("enter first day")
    dat=int(input("enter day number"))
    lis=['sun',"mun",'tue','wed','thu','fir','sat']
    step1=(dat+7)%7+lis.index(day)
    if step1>7:
    step1=step1-8
    print(lis[step1])

      Our Program is right but if you want other program then

      Correct code is :-
      day=input("enter first day")
      dat=int(input("enter day number"))
      lis=['sun',"mun",'tue','wed','thu','fir','sat']
      #
      step1=(dat+7)%7-1+lis.index(day)
      if step1>6:
      step1=step1-7
      print(lis[step1])
      #Is this correct

      Wrong program :-

      #It can be done more easily
      day=input("enter first day")
      dat=int(input("enter day number"))
      lis=['sun',"mun",'tue','wed','thu','fir','sat']
      step1=(dat+7)%7+lis.index(day)
      if step1>7:
      step1=step1-8
      print(lis[step1])

      day=input("Enter first day: ")
      dat=int(input("Enter day number: "))
      lis=["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]

      Cal = (dat) % 7 + lis.index(day.title())

      print(lis[Cal])
