Help with gregorian calendar

[osval]

I'm trying to calculate how many days left in the year but it doesn't work

this is my code:

public class Calculate
{
public static void main (String args[])
{
GregorianCalendar today = new GregorianCalendar();
GregorianCalendar nyear = new GregorianCalendar(365,12,31);
long daysleft= nyear .get(nyear .DAY_OF_YEAR) - today.get(today.DAY_OF_YEAR);


System.out.println( daysleft);
}

}

thanks

DateFormat df = new SimpleDateFormat("ddMMMyyyy");
Calendar today = Calendar.getInstance();
System.out.println("today = " + df.format(today.getTime()));
Calendar endOfYear = Calendar.getInstance();
endOfYear.set(2007, 11, 31);
System.out.println("endOfYear = " + df.format(endOfYear.getTime()));
int daysRemaining = endOfYear.get(Calendar.DAY_OF_YEAR) -
                        today.get(Calendar.DAY_OF_YEAR);
System.out.println("days remaining = " + daysRemaining);
GregorianCalendar start = new GregorianCalendar();
GregorianCalendar end = new GregorianCalendar(2007, 11, 31);
long daysLeft = end.get(Calendar.DAY_OF_YEAR) -
              start.get(Calendar.DAY_OF_YEAR);
System.out.println("daysLeft = " + daysLeft);
