Question

USE PYTHON ONLY PLEASE

Zeller’s congruence is an algorithm developed by Christian Zeller to calculate the day of the week. The formula is

h = (q + 26(m+1)//10 + k + k//4 +j//4 +5j) % 7

where

- h is the day of the week (0: Saturday, 1: Sunday, 2: Monday, 3: Tuesday, 4: Wednesday, 5: Thursday, 6: Friday).
- q is the day of the month.
- m is the month (3: March, 4: April, ..., 12: December). January and February are counted as months 13 and 14 of the previous year.
- j is year//100.
- k is the year of the century (i.e., year % 100).

Write a program that prompts the user to enter a year, month, and day of the month, and then it displays the name of the day of the week.

Sample Run 1

Enter year: (e.g., 2008): 2013

Enter month: 1-12: 1

Enter the day of the month: 1-31: 25

Day of the week is Friday

Sample Run 2

Enter year: (e.g., 2008): 2012

Enter month: 1-12: 5

Enter the day of the month: 1-31: 12

Day of the week is Saturday

Hint: Use the // operator for integer division. January and February are counted as 13 and 14 in the formula, so you need to convert the user input 1 to 13 and 2 to 14 for the month and change the year to the previous year.

Answer 1

Here is your code :-

year=int(input('Enter year: (e.g., 2008): '))
month=int(input('eEnter month: (1-12) : '))
day=int(input('enter day of the month : (1-31) : '))
q=day
j=year/100
k=year%100
m=month
h=((q+1)+(26*(m+1)/10)+k+(k/4)+(j/4)+(5*j))%7
day_name=['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday']
print('Day of the week is :',day_name[int(h)])

Output :
