ConcreteHolidays

The ConcreteHolidays gem was built to calculate if a given date is a holiday using plain old ruby objects.

class MyHolidays < ConcreteHolidays
  def default_holidays
    add_holiday ConcreteHolidays::NewYearsDayObserved

    add_holiday ConcreteHolidays::ChristmasEve
    add_holiday ConcreteHolidays::ChristmasObserved
    add_holiday ConcreteHolidays::NewYearsEve
  end
end

holidays = MyHolidays.new
holidays.holiday?(date)

Create a custom holiday (class)

The class must implement self.date(year) and return a date or array of dates.

class MyBirthday
  def self.date(year)
    Date.new(year,3,14)
  end
end

holidays = ConcreteHolidays.new
holidays.add_holiday MyBirthday
holidays.holiday?(date)

Create a custom holiday (instance)

The instance must respond to date(year) and return a date or array of dates.

class MyBirthday
  def date(year)
    Date.new(year,3,14)
  end
end

holidays = ConcreteHolidays.new
holidays.add_holiday MyBirthday.new
