Custom Group Calendar Display on Web Page

I would like a web page to be written for me that allows for the display of multiple peoples' calendars side-by-side in columns. I am fine with controlling "settings" via a flat file--no web controls needed. The feed of calendar information will be coming from Zimbra servers, using any of these protocols: ics, json, xml, rss, atom Additional documentation for the Zimbra REST API is here: [login to view URL]:Zimbra_REST_API_Reference:Get_Calendar Some desired settings: (1) number of columns to display, (2) URL for each column's feed, (3) time between refresh in minutes, (4) colors for each column's entries--color for "busy","out of office" and "tentative" appointments, (5) start and end times for display, i.e., start at 7:00 AM and end at 6:00 PM, (6) display name for each column Each column should have a space at the top for displaying "all day" entries, then should have light lines to indicate 15 minute time spans and slightly heavier lines to demarcate hours. Times should be listed on the far left and far right. Each column should have the display name in bold above it. Above all, the interface needs to look clean, aesthetically pleasing and easy to read. The purpose of this display is to provide a wall-mounted monitor which will display the calendars of relevant staff in that area.
