Date::Calendar::Hijri - Arithmetic variant of the Hijri calendar
Converting a Gregorian date (e.g. 7th February 2021) into Hijri
use Date::Calendar::Hijri; my Date $dt-greg; my Date::Calendar::Hijri $dt-hijri; $dt-greg .= new(2021, 2, 7); $dt-hijri .= new-from-date($dt-greg); say $dt-hijri; # --> 1442-06-24 say $dt-hijri.strftime("%A %d %B %Y"); # --> Yaum al-Ahad 24 Jumaada al-Thaani 1442
Converting a Hijri date (e.g. 1 Muharram 1443) into Gregorian
use Date::Calendar::Hijri; my Date::Calendar::Hijri $dt-hijri; my Date $dt-greg; $dt-hijri .= new(year => 1443, month => 1, day => 1); $dt-greg = $dt-hijri.to-date; say $dt-greg; # --> 2021-08-10
The real Hijri calendar is an observational calendar. That means that calendar events, such as switching from a month to the next, depend of the observation of some astronomical events, such as observing the moon crescent after a new moon. But there is an unofficial arithmetic variant, which differs from the real one by one or two days.
Date::Calendar::Hijri is a class representing dates in the arithmetic variant of the Hijri calendar. It allows you to convert a Hijri date into Gregorian (or possibly other) calendar and the other way.
