This mu-plugin adds support for date based archives for public custom post types that are registered with the has_archive property set to true. It adds rules for year, month, and date archives.
For example, if you register a custom post type of books for a website at http://example.com, the following URLs will be be active if you are using pretty permalinks (providing posts fit within the timeframe) :
http://example.com/books/2015
http://example.com/books/2015/04
http://example.com/books/2015/04/20
This plugin requires PHP 5.3 or later and WordPress 3.0 or later.
The preferred installation method is via Composer. This plugin can be found on Packagist.
Additionally, you can download a release and then upload to the mu-plugins directory. You will need to add file in the mu-plugins directory that loads the cpt-date-archives.php file from the plugin root directory.
