{
    Scanner userIn = new Scanner(System.in);
    int dates, day, dayOfMonth, month, century, year;

    System.out.print("Enter year(e.g:2001): ");
    year = userIn.nextInt()%100;

    System.out.print("Enter month(1-12): ");
    month = userIn.nextInt();

    System.out.print("Enter days(1-31): ");
    dayOfMonth = userIn.nextInt();

    System.out.print("Days of the week are: ");

    century = year/100;

    if (month == 1){
        month = 13;
        year = year-1;

    day = ((dayOfMonth +((26*(month+1))/10) + year + (year/4) + (century/4) + (5*century))%7);

    if (day == 0){
        System.out.println("saturday");
    }
    if (day == 1){
        System.out.println("sunday");
    }

    }
    if (day == 3){
        System.out.println("tuesday");
    }
    if (day == 4){
        System.out.println("wednesday");
    }
    if (day == 5){
        System.out.println("thursday");
