Creating Activity View Filter: "This Week's Activities"

I'd really like to create a view called "This week's activities". To do this, I'd need a filter that would capture the week, or if I couldn't have that, I could create a view called "Plus five, Minus five" which would put into view all the activities on for today, as well as appts five days back and five days forward.

If this can't be done, can anyone share with me something that would help me use the coding correctly?
