NAME
       Date::Hijri - Perl extension to convert islamic (hijri) and gregorian dates.


SYNOPSIS
         use Date::Hijri;

         # convert gregorian to hijri date
         my ($hd, $hm, $hy) = g2h($gd, $gm, $gy);

         # convert hijri to gregorian date
         my ($gd, $gm, $gy) = h2g($hd, $hm, $hy);


DESCRIPTION
       This simple module converts gregorian dates to islamic (hijri) and vice versa.

       The dates must be given as an array containing the day, month and year, and return the corresponding date
       as a list with the same elements.


EXAMPLES
         #!/usr/bin/perl -w

         use Date::Hijri;

         print join("-", g2h(22,8,2003));  # prints 23-6-1424
         print join("-", h2g(23,6,1424));  # prints 22-8-2003

DISCLAIMER
       I haven't really tested if the converted dates are right and hope someone will point out mistakes.

       Hijri calculations are very difficult. The islamic calendar is a pure lunar calendar, the new month
       starts by a physical (i.e. human) sighting of the crescent moon at a given locale. So it depends on
       several factors (like weather) that make it unreliable to calculate islamic calendars in advance. As a
       result the dates calculated by Date::Hijri can be false by one or more days.

       Please see http://www.rabiah.com/convert/introduction.html for further explanation.

       I'm not a muslim, but interested in Islamic culture, religion and calendar system. I believe in the
       Internet as a chance to realize that we live in a small world with multiple cultures, religions and
       philosophies. We can learn from others and develop tolerance, respect and understanding.
