//Sunday, Monday, Tuesday,
//Wednesday, Thursday, Friday, Saturday,
public static String wk[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
// display :This is my first program
System.out.println("This is my first program!");
week();
}

public static int week()
{
Scanner sc=new Scanner(System.in);
int i=sc.nextInt();
if(i==0) return 0;
else if(i<0||i>7) week();
else System.out.println(wk[i-1]);
return 1;

}
