RE: Date calculations

["Clapham, Paul" <pclapham@xxxxxxxxxxxxx>]

You just got zapped by one of the more idiotic features of Java.  In
Calendar, months are numbered starting at zero, so "08" represents
September.  Your original value was "September 31", which is normalized to
October 1, and the rest becomes obvious once you know that.

Hmmm .... why does

            Calendar c = new GregorianCalendar(2002, 08, 31);
            c.add(Calendar.DATE, 1);

give me

            the calendar c how has a date of 2002/10/02

Am I doing this wrong?  I want something smart enough to consider the
current month/day.
