From the phpScheduleIt website:

" phpScheduleIt is a web application that attempts to solve the problem of scheduling and managing resource utilization. It provides a permissions-based calendar that allows users to self-register and reserve resources and the tools to manage those reservations.

Some typical applications are conference room, equipment, or work shift scheduling.
