The Ruby holidays gem has been released and I'm looking for
contributors to help create regional holiday definition files.  This
gem provides a set of functions for looking up public holidays around
the world.

A quick example:

  require 'holidays'
  require 'holidays/ca'

  # Lookup Canada Day
  date = Date.civil(2007,7,1)
  Holidays.by_day(date, :ca)
  => [{:name => 'Canada Day',...}]

  # Canada Day is July 1 except when July 1 is a Sunday, then it moves
to
  # July 2
  date = Date.civil(2007,7,2)
  Holidays.by_day(date, :ca, :observed)
  => [{:name => 'Canada Day',...}]

  # Check if this is a holiday in British Columbia, Canada
  date.holiday?(:ca_bc)
  => true

There are a lot of countries in the world and contributors are invited
to create or improve a holiday definition file for any region.  Sample
definition files can be found at http://code.dunae.ca/svn/holidays/trunk/data/
- get in touch if you would like to help out: alex [at] dunae dot  ca.
