Why set all those variables if they serve no purpose :/

      int day = cal.get(Calendar.DATE);
      int month = cal.get(Calendar.MONTH) + 1;
      int year = cal.get(Calendar.YEAR);
      int dow = cal.get(Calendar.DAY_OF_WEEK);
      int dom = cal.get(Calendar.DAY_OF_MONTH);
      int doy = cal.get(Calendar.DAY_OF_YEAR);
