# use python only please zeller’s congruence is an algorithm

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.
