Thread: Zellar's Congruence error

Hello everyone, so I'm brand new to java (3 weeks of instruction) I think I'm close on this formula(Zellar's Congruence), but I'm getting "error: cannot find symbol" on line 33 when I attempt to compile, I've re-written the formula a couple times and am continuing to get this error. Any help or insight would be much appreciated. Thanks

import java.util.Scanner;
public class Project1_3_7 {
 
    public static void main(String[] args) {
    	Scanner scanner = new Scanner (System.in);
 
		final String[] DAY_OF_WEEK = {"Saturday", "Sunday", "Monday",
			"Tuesday", "Wednesday", "Thursday", "Friday"};
 
    	System.out.print("Enter year: (e.g, 2012): ");
    	int year = scanner.nextInt();
 
    	System.out.print("Enter Month: 1-12: ");
    	int month = scanner.nextInt();
 
    	System.out.print("Enter the day of the month: 1-31: ");
    	int dayOfMonth = scanner.nextInt();
 
    	if (month == 1)
    		month = 13;
    	else if (month == 2)
    		month = 14;
 
    	int century 	  = year / 100;
    	int yearOfCentury = year % 100;
 
    	int dayOfWeek = (day + ((26*(month + 1)) / 10) +
    		yearOfCentury + (yearOfCentury / 4) + (century / 4) +
    		(5 * century)) % 7;
 
    	int answer = (int)dayOfWeek;
 
    	System.out.println("Day of the week is " + DAY_OF_WEEK[answer]);
 
    }
}

I figured it out, just a stupid mistake that I think stemmed from me working on this too long...

int dayOfWeek =(dayOfMonth +((26*(month + 1)) / 10) +
    		yearOfCentury + (yearOfCentury / 4) + (century / 4) +
    		(5 * century)) % 7;

I managed to mix up what variable i used for the "dayOfMonth"...
