A gem providing "time travel" and "time freezing" capabilities, making it dead simple to test time-dependent code. It provides a unified method to mock Time.now, Date.today, and DateTime.now in a single call.

The official date library for Ruby.

Chronic is a natural language date/time parser written in pure Ruby.

ice_cube is a recurring date library for Ruby. It allows for quick, programatic expansion of recurring date rules.

Precise and fast user agent parser and device detector, backed by the largest and most up-to-date agent and device database

Little helper for the classes Date, DateTime and Time. // date_time_compare.rb: Allows to compare Date and Time objects (allows to sort by mixed Date/Time-keys). // date_creator.rb: New date creations: Date#new_by_mday: Allows "Third sunday in june 2010"... // date_locale.rb: Localization of Date, DateTime and Time. strftime gets a optional parameter to determine the language. Default is en, or if locale is used the current locale.

Moment.js is a lightweight javascript date library for parsing, manipulating, and formatting dates. This gem allows for its easy inclusion into the rails asset pipeline.

Date and DateTime don't have sensible constructors. You can't construct one using an existing Date/Time, nor by passing a string to be parsed. Instead you have to call special-purpose routines. This gem adds some sensible options to the existing modes of the constructors

date-formats - read / parse and print dates (and times) from around the world

Render a date/time span according to an strftime pattern. Only works with sensibly ordered date-formats (so not US!)

= Livedate A simple Rack middleware that parses a dates using Chronic, and returns the result in a standardized manner. The idea is to use this to verify the input in date input fields using AJAX, to provide immediate feedback to the user. == Usage Include Livedate in your middleware stack. In Rails, this is done in environment.rb config.gem 'livedate' config.middleware.use "Livedate" Specify the desired date + datetime formats you want too. Default error message for strings that Chronic can't pass can also be provided. The defaults are: config.middleware.use "Livedate", :date_format => '%Y-%m-%d', :datetime_format => ''%Y-%m-%d %H:%M', :invalid_format => '' This will catch requests to /parsedate. Use GET requests and provide a parameter 'date' or 'datetime'. The value will be parsed by Chronic and returned formatted as 2009-01-01 or 2009-01-01 12:45, depending on the parameter name. == Scripts There are two generators available to get simple javascripts that use livedate. Both will replace the contents on input elements with classes .date or .datetime on change with the result from the Chronic parse. script/generate livedate_jquery script/generate livedate_prototype Will put the appropriate version of the script in your public/javascripts directory. Feel free to change these if you need a different behavior.

= input_chronic A simple Rack middleware that parses a dates using Chronic, and returns the result in a standardized manner. The idea is to use this to verify the input in date input fields using AJAX, to provide immediate feedback to the user. == Usage Include "input_chronic" in your middleware stack. In Rails, this is done in environment.rb config.gem 'bjornblomqvist-input_chronic', :lib => 'input_chronic', :source => 'http://gems.github.com' config.middleware.use "input_chronic" This will catch requests to /gems.github.com/bjornblomqvist/input_chronic. Use GET requests and provide a parameter 'date' or 'datetime'. The value will be parsed by Chronic and returned formatted as 2009-01-01 or 2009-01-01 12:45, depending on the parameter name. Don't forget to add the javascript found at /javascript/input_chronic.js This is also implemented by catching the request before it reaches rails. To use this on a text input add the class chronic_date or chronic_datetime <input type="text" class="chronic_datetime" /> == Copyright Copyright (c) 2009 Erik Hansson, Bjorn Blomqvist.

counter_culture provides turbo-charged counter caches that are kept up-to-date not just on create and destroy, that support multiple levels of indirection through relationships, allow dynamic column names and that avoid deadlocks by updating in the after_commit callback.

Helper for creating a date or date-time picker that uses the Unobtrusive Date-Picker Widge

Humans want to think of date and datetime attributes in a natural manner. Standard ruby Date and DateTime objects do not support this well.

Rails gem/plugin that implements an ActiveRecord validation helper called validates_as_date_time which validates U.S. dates, times, and date-times
