Here's some code that gives 419, the same thing I worked out by hand:
import java.util.*;
public class gctest {
public static void main(String[] argv) {
Calendar a, b;
a=new GregorianCalendar(1991,01,15); // 1991-FEB-15
b=new GregorianCalendar(1992,03,10); // 1992-APR-10
System.out.println((b.getTime().getTime()-a.getTime().getTime())/(1000*60*60*24));
}
}
Perhaps you forgot to subtract 1 for the month numbers since in Java January=0?
Good luck,
Jim
