Hi,

I'm using JB6 + JDK1.4.
Then, I would like to do something like this:

    GregorianCalendar firstdate = new GregorianCalendar(Year1, Mouth1, 
Day1);
    GregorianCalendar lastdate = new GregorianCalendar(Year2, Mouth2, Day2);
    int numberofdays = lastdate - firstdate; // THIS LINE DOESN'T WORK

I know that minus operator isn't applied to GregorianCalendar.
But, how to calc this difference?
