Need help with Zeller's Congruence

[quem]

I am getting a correct result for recent dates but when I go back a couple of years it's incorrect.

I feel so stupid, I am a major noob at math & coding and this is for a lab so I could really use some help.

Thanks

import java.util.Scanner;
public class Lab02 {

	/**
	 * @param args
	 */
	public static void main(String[] args) 
	{
		Scanner keyboard = new Scanner(System.in);
		
		{
			//step1
			System.out.println("Enter a month, January = 1, February = 2, ... December = 12:");
			int month = keyboard.nextInt();
			
			//step2
			System.out.println("Enter a day, 1-31:");
			int day = keyboard.nextInt();
			
			//step3
			System.out.println("Enter a year:");
			int year = keyboard.nextInt();
			
			//step4
			if (month <= 2)
			{	month = month + 10;
				year = year - 1;
			}
				else
				month = month - 2;
			
			//step5
			int monthCor = (month * 26 - 2) / 10;
			
			//step6
			int century = year / 100;
			
			//step7
			int centuryRem = year % 100;
			
			//step8
			int yearCor = (century * 5) + centuryRem;
			yearCor = (century / 4) + (centuryRem / 4);
	
			
			//step9
			int weekday = (day + monthCor + yearCor) % 7;
		
			System.out.println(weekday);
			
		}

Your step #8 is incorrect; see this: Zeller's congruence - Wikipedia, the free encyclopedia

kind regards,

I see now, yearCor was being written over by the second equation.
This worked:

int yearCor = (century * 5 + century / 4 + centuryRem / 4) + centuryRem;

Thanks Again!
