Modifying Calendar.DAY_OF_WEEK issue

Question

Hi,
I'm trying to get a report to run so that it gets data for the previous "business day" (M-F). So if a user comes in on Monday, he would get a report for Friday. However, I'm running into an issue where I do the following (after I already get the Calendar object set to the Locale.US, and EST TimeZone):
calendar.add(Calendar.DAY_OF_MONTH, -1);
System.out.println(calendar.get(Calendar.DAY_OF_WEEK));
// check for Saturday/Sunday
if(calendar.get(Calendar.DAY_OF_WEEK) == 1)
  calendar.add(Calendar.DAY_OF_MONTH, -2); // FRIDAY
if(calendar.get(Calendar.DAY_OF_WEEK) == 7)
  calendar.add(Calendar.DAY_OF_MONTH, -1); // FRIDAY
System.out.println(calendar.get(Calendar.DAY_OF_WEEK));
// WRONG DAY OF WEEK - I get a 3 not a 1 after the first .add() methodSo I'm not sure why it's acting strange, I still get the correct date (14) after the first .add but I'm kinda lost as to why the other comparisons do not work.
Thanks in advance,
Lior

Reply, I'm not sure why this is happening again, but I'm running the program (my system date is working fine and I'm getting the right date when I print out the getTime() method) and getting the wrong day of the week:
public class CalendarTest {
  public static void main(String[] args) {
     Calendar now = Calendar.getInstance();
     switch (Calendar.DAY_OF_WEEK) {
          case Calendar.MONDAY:
               System.out.println("MONDAY"); break;           
          case Calendar.TUESDAY:
               System.out.println("TUESDAY"); break;           
          case Calendar.WEDNESDAY:
               System.out.println("WEDNESDAY"); break;           
          case Calendar.THURSDAY:
               System.out.println("THURSDAY"); break;           
          case Calendar.FRIDAY:
               System.out.println("FRIDAY"); break;           
          case Calendar.SATURDAY:
               System.out.println("SATURDAY"); break;           
          case Calendar.SUNDAY:
               System.out.println("SUNDAY"); break;
          default: break;      
  } // end main
}I'm getting SATURDAY when running this test program. Why is this happening? I'm not sure at all.
Thanks
