Calendar

I'd like to make a running calendar. It'll start with today's date, and shows events scheduled for the next 5 to 7 days.

Sunday	Monday	Tuesday	Wednesday	Thusday	Friday	Saturday
Football	PHS201	PHS201			X-Files
Simpsons	Mon Nite Football

There should also be a form-based event entry.

Ideally, events should be lumped into categories, and then allow people to see only events in the categories they are interested in.
