OpenSkedge is inspired by an old PHP 4 application, Employee Scheduler, and is a flexible scheduling application designed for companies and organizations (such as education institutions with student workers) which require fluid shift scheduling.
It's a PHP 5 web application built on the solid and powerful Symfony2 framework and utilizing the Doctrine ORM. It is licensed under the GNU GPL version 3 or later.
I no longer actively develop or maintain it, but I will still accept contributions and address any critical issues that might arise.
