Need help with Zeller's Congruence

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

Code:

---

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!
