Khalid, you might want to check out the following URLs. The first
talks about the difficulty you talk about. The second provides an
algorithm for determining the visibility of the new moon (although it
is based in Makkah). The algorithm could easily be converted to perl,
and I imagine you'd find M$ use it. (although they might base it at
Bill's house, rather than Makkah :).
It would be excellent to see a DateTime::Calendar module for Hijri
dates, are you willing to do this? You could offer two dates:
Visibility at Makkah and local visibility. (You can get the local by
using the timezone offset in the provided algorithm).

Subject: Hijri dates
Hello to you all... is there anybody that has found a way to get other
modes of dates such as Hijri using perl...!? there are other calendar
system that are not wildly used throughout the world but are still used
indeed. the hijri system is based on lunar calculations and is about ten
days less per year. It's main problem thought is that the month number of
days is unpredictable (based on the moon of course) Microsoft has
somehow
been able to figure out a way to calculate the hijri date and made it
available in Windows.
Please advice if you know of a way to get perl to provide Hijri dates..
Regards,
Khalid,,,

There are 10 kinds of people:
those that understand binary, and those that don't.
The day Microsoft makes something that doesn't suck
is the day they start selling vacuum cleaners
