这对你有用

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");    Date date1 = df.parse("10/08/2013");    Date date2 = df.parse("21/08/2013");    Calendar cal1 = Calendar.getInstance();    Calendar cal2 = Calendar.getInstance();    cal1.setTime(date1);    cal2.setTime(date2);    int numberOfDays = 0;    while (cal1.before(cal2)) {        if ((Calendar.SATURDAY != cal1.get(Calendar.DAY_OF_WEEK))&&(Calendar.SUNDAY != cal1.get(Calendar.DAY_OF_WEEK))) { numberOfDays++;        }        cal1.add(Calendar.DATE,1);    }    System.out.println(numberOfDays);
