Date problem!!!!!!Plz help.....

Hi All,
I know that the Date class has 2 constructors:-
1- Date(long date)
 Constructs a Date object using a milliseconds time value.
  date - milliseconds since January 1, 1970, 00:00:00    
  GMT.A negative number indicates the number of
  milliseconds before January 1, 1970, 00:00:00 GMT.
2- Date(int year, int month, int day)
 Constructs a Date object initialized with the given year, month, and day.
      year - year-1900
      month - 0 to 11
      day - 1 to 31

If i have the number of days of some date but from 1900..
The number of days from 1/1/1900 to 27/2/1978 == 28548 days.
I need to know if there is any method in the Date class that can take this number of days and returns the corressponding date?
I need this method because the calaulation to convert this number to milliseconds will not be very accurate!!!

Any comment will be very helpfull...
Thanx in advance.

try this:

java.util.GregorianCalendar cal = new java.util.GregorianCalendar(1900, 1, 1);
cal.add(cal.DATE, 28548);
System.out.println("" + cal.getTime().toString());

I am not sure that 27/2/1978 is 28548 after 1/1/1900!

Hi Venci75
i really didn't understand the code!!!
will u please explain it to me?
Thanx in advance
First - you create an instance of GregodianCalendar. This is needed, because this object cares of the Gregorian date change. The Calendar objects contain the current date. So - you create your gregorian calendar with the 01/01/1900 as a current date. The calendar object has a method add() to which you must supply 2 parameters:
1. type of the field - years, days (date), months, weeks
2. the amount
This line:
cal.add(cal.DATE, 28548);
will change the current date by adding 28548 days to it.

cal.getTime() returns the calendar current date as a Date object. I used cal.getTime().toString() to display the result, but you can convert the date to String by using the SimpleDateFormat class (for example).

I tried the code & had the following date:
Sat Apr 01 00:00:00 GMT+03:00 1978
but my date 27/2/1978!!
Do you think the number of days that was added is wrong??

Thanx Venci75
