Calcium is a Web Calendar application. It will run on nearly any machine with a web server that can run Perl CGI scripts; a web browser is all you need to view, edit, and manage any number of calendars from any network connected computer. All administration is also done with your browser. Calcium calendars can be used for:
* scheduling meetings, vacations, or any kind of events
* keeping track of employee availability
* room or equipment reservations
* anything else you can think of!
