Business Time for Germany
The business_time brings business time & days calculations to ActiveSupport.
This gem pre-configures it for all german holidays, both fixed (Neujahr, Tag der Arbeit, Tag der Deutschen Einheit, Weihnachten) and moving (Easter & it's friends Pfingsten and Himmelfahrt). The easter date is calculated using the date_easter gem, Pfingsten & Himmelfahrt are calculated based on that, so no hard-coded values here.
The holidays are defined for
(2000..2035), which should be sufficient (on Ruby 1.9 they can be defined much further up, but
Times after 2037 tend to fail with
time out of range on Ruby 1.8.7...)
gem install business_time-de # OR gem 'business_time-de' require 'business_time-de' 7.business_days.after(Date.parse("2012-03-28")) # => "2012-04-10" (because of easter)
For more information on the usage of the business_time gem please check out it's documentation.
