typecast gregoriancalendar object as date object?

[achana chan]

Hi I need to do some simple date calculations, like find out the number of days between two dates e.g.

Date now = new Date();
String christmasDate = "Dec 24, 2004 12:00 PM";
Date var_christmasDate = db_format.parse(christmasDate);
double var_diffInMillis = var_christmasDate.getTime() - now.getTime();

Obviously I can do this using Date objects.
But I have codes which use GregorianCalendar objects. The long (workable) way is to typecast the GregorianCalendar objects and then parse them back to Date objects for the calculation.
That seems rather cumbersome!
Is there a more elegant way of subtracting (or adding) two GregorianCalendar objects without to get the difference in number of days?
TIA :-)

hi,
check out if this kinda code can be of help!
import java.util.*;
class GregT{
public static void main(String ar[]){
Calendar gcala=new GregorianCalendar(2004,01,17,8,32,30);//Jan 17th 2004
Calendar gcaln=new GregorianCalendar(2004,03,17,8,32,30);//March 17th 2004
int var1=gcala.get(Calendar.DAY_OF_YEAR);
int var2=gcaln.get(Calendar.DAY_OF_YEAR);
System.out.println(var2-var1);

}
}

Thanks for your time and input.
Works out to about the same number of lines of codes ;-)
