Here's that code modified to something much more like what you specified. It prints the number of weeks between to dates inclusive, eg. there are 4 weeks between "Feb 1, 2003" and "Feb 28, 2003" not 3.something.
I am now using the number of milliseconds in a day instead of in a week. The value 86400 is 24*60*60.
I've also changed the input format to support days like
June 1, 2003. Note you will need to put the args in "" when you run it because of the spaces.
import java.util.Date;
import java.text.*;
public class TestTP
     static double MILLIS_PER_DAY = 86400*1000;
     public static void main( String args[ ] ) {
          double weeks;
          Date d0,d1;
          for (int i = 0; i<(args.length-1); i+=2)
               d0 = parseDate(args);
               if(null == d0)System.out.println(args[i]+" is bad");
               else
                    d1 = parseDate(args[i+1]);
                    if(null == d1)System.out.println(args[i+1]+" is bad");
                    else
                         double days = dayDiff(d0,d1); // get difference in days
                         weeks = (1+days)/7;               // make it inclsive in weeks
                         System.out.println(args[i+1]+" is "+weeks+" weeks after "+args[i]+" inclusive");
     static Date parseDate(String ds)
          Date dt;
          SimpleDateFormat sdf = new SimpleDateFormat("MMM d, yyyy");
          sdf.setLenient(false);
          try{dt = sdf.parse(ds);}
          catch (ParseException e){dt = null;}
          return dt;
     static double dayDiff(Date d0, Date d1)
          return (d1.getTime()-d0.getTime())/(MILLIS_PER_DAY);
