Chronik is a project mainly written in Ruby, it's free.
Dates class parser
Chronik is a very small library used to translate dates' classes, as seen on public transport timetables, like "Weekdays" or "Easter and Christmas", to actual dates (or weekdays if it directly relates to them). It is inspired by mojombo/chronic.
gem install chronikMost basic usage: translate day(s) of the week to integer (from 0 to 6)
require 'chronik'
label = Chronik::Label.new "Soboty" # Polish word for Saturday
label.weekdays #=> [6]Slightly more complicated: get the dates of given holidays. Since holidays are repeted every once in a year and we don't want an infinite array, we need to specify a date range.
require 'chronik'
require 'date'
range = Date.new(2011,1,1)..Date.new(2011,12,31)
label = Chronik::Label.new "Wielkanoc" # Polish word for Easter
label.holidays(range) #=> [Date.new(2011,4,24), Date.new(2011,4,25)]Currently only Polish language is supported, but it is super easy to add another language. Look for constants in lib/chronik/chronik.rb file.
