datejs-rails wraps the datejs library in a rails engine for simple use with the asset pipeline provided by rails 3.1. From version 2.0 onward, the gem includes the fork of Datejs maintained by Eric Lindvall

datejs extends the Javascript date object to allow for simple date parsing, calculation, and formatting.

There are a number of more suitable ways to work with Dates in JavaScript these days, as well as a number of better ways to work with JavaScript in Rails. This projects in now archived and will see no more releases.

Add the following to your gemfile:

gem 'datejs-rails'

Add the following directive to your Javascript manifest file (application.js):

//= require date

This will require the en-US version of datejs. All other localizations are available as well. For instance, you could instead:

//= require date
//= require date/fr-FR

Optionally, require extras.js for strftime-style FormatSpecifiers.

//= require date/extras
