hijri is full lunar Islamic Hijri calendar lib for ruby.
The Islamic calendar or Muslim calendar or Hijri calendar: is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to date events in many Muslim countries (concurrently with the Gregorian calendar), and used by Muslims everywhere to determine the proper day on which to celebrate Islamic holy days and festivals. The first year was the year during which the emigration of the Islamic prophet Muhammad from Mecca to Medina, known as the Hijra, occurred. Each numbered year is designated either H for Hijra or AH for the Latin anno Hegirae (in the year of the Hijra).[1] A limited number of years before Hijra (BH) are used to date events related to Islam, such as the birth of Muhammad in 53 BH.[2] The current Islamic year is 1431 AH, from approximately 18 December 2009 (evening) to 6 December 2010 (evening).

Add this line to your application's Gemfile:
gem 'hijri'
And then execute:
$ bundle
Or install it yourself as:
$ gem install hijri
require 'hijri'
# you can create hijri date from stdlib Date class.
h = Date.today.to_hijri # => #<Hijri::Date:0x007f875e8c84e8 @year=1436, @month=2, @day=16>
# or you can initialize new one.
hijri = Hijri::Date.new 1430, 1, 3 # => #<Hijri::Date:0x007f875e8dbb38 @year=1430, @month=1, @day=3>
# or you can get today hijri date directly.
today = Hijri::Date.today # => #<Hijri::Date:0x007f875e8d8410 @year=1436, @month=2, @day=16>
# and you can convert hijri date to greogian date also.
hijri.to_greo # => #<Date: 2009-01-01 ((2454833j,0s,0n),+0s,2299161j)>
# and there is DateTime too
date_and_time = Hijri::DateTime.now # => #<Hijri::DateTime:0x007f875e8eac00 @year=1436, @month=2, @day=16, @hour=14, @minute=14, @second=39, @zone="+03:00">
# hijri support strftime method with the same options as Greogian date format method
Hijri::DateTime.now.strftime('%c') # => "Ahad Rabia I 20 16:00:25 1436"This library aims to support and is tested against the following Ruby implementations:
- MRI 1.8.7
- MRI 1.9.2
- MRI 1.9.3
- MRI 2.0.0
- MRI 2.1.0
- MRI 2.2.0
- MRI 2.3.0
- MRI 2.4.0
- MRI 2.4.1
- MRI 2.5.1
- MRI 2.6.2
- JRuby 1.8 mode
- JRuby 1.9 mode
If something doesn't work on one of these Ruby versions, it's a bug.
This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.
If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.
