Drupal - Interactive Calendar

My client needs multiple events pages on their current Drupal site replaced with an interactive calendar page. The calendar must allow for unlimited categories. It must also allow for administrators to fully add, edit and delete events but allow view only access to all other users visiting the page. Also, the home page display events from the calendar. Users should be able to pick what category of events will display (i.e. latest 3 added, top 5 upcoming, etc). ## Deliverables Attached is a requirements document for multiple changes. Please refer to the detailed description for the interactive calendar only.
