import java.util.Calendar;
public class MyTime {
    /**
     * 计算某个月的工作天数，周六周日不算
     * @param year,month
     * @return the number of workdays
     */
public int WorkDays(int year,int month){

int days=0;
Calendar cal=Calendar.getInstance();
Calendar cal2=Calendar.getInstance();
cal.set(Calendar.YEAR,year);
cal.set(Calendar.MONTH,month-1);
cal.set(Calendar.DAY_OF_MONTH,1);
cal2.set(Calendar.YEAR,year);
cal2.set(Calendar.MONTH,month);
cal2.set(Calendar.DAY_OF_MONTH,1);
while(cal.compareTo(cal2)!=0){
if((cal.get(cal.DAY_OF_WEEK)!=7)&&(cal.get(cal.DAY_OF_WEEK)!=1)) {
days++;
//System.out.println(cal.get(cal.DAY_OF_WEEK));
}
cal.add(cal.DATE,1);
}

return days;
}
/**
 * @param args
 */
public static void main(String[] args) {
// TODO Auto-generated method stub
        MyTime mt=new MyTime();
        int k=mt.WorkDays(2006,3);
        System.out.print(k);
}
