How to Convert a Gregorian date to Hijri format
thanks for all

In Access 2002, there is an option to use Hijri Calendar, you can find it in tools, options, international.

First:
I am sorry for previous response, I thought you said you CANT use Hijri calendar in access

Then:
use the following code to change from georgian date to Hijri

Code:

---

        Dim hj As New CultureInfo("ar-SA")
        Dim hjyr, hjmo, hjday As Integer, gdate As DateTime
        gdate = #11/11/2002# 'or any other date
        hj.DateTimeFormat.Calendar = New HijriCalendar()
        hjyr = hj.DateTimeFormat.Calendar.GetYear(gdate)
        hjmo = hj.DateTimeFormat.Calendar.GetMonth(gdate)
        hjday = hj.DateTimeFormat.Calendar.GetDayOfMonth(gdate)
