下面的代码有什么问题？它为一年中的任何日期提供错误的日期。

import java.util.Scanner;
import java.util.Calendar;
public class Solution {
    public static String getDay(String d, String m, String y) {

        String[] days = {"SUNDAY", "MONDAY", "TUESDAY", "WEDNESDAY", "THURSDAY", "FRIDAY", "SATURDAY"};
        Calendar c = Calendar.getInstance();
        c.set(Integer.parseInt(y), Integer.parseInt(m), Integer.parseInt(d)); 
        return days[c.get(Calendar.DAY_OF_WEEK) - 1]; 
    }
public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        String m = in.next();
        String d = in.next();
        String y = in.next();

        System.out.println(getDay(d, m, y));
    }
}
