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.
