I have a list of events (custom content type *event*) shown in a view.

There are several events each week.  Each week has a **date** field, *date*, that records the date that the event will be held.

I would like to group the events by the week of the year that they occur.  For example:

 * Next week
 * Two weeks from now
 * Three weeks from now
 * Four weeks from now

Is there a fancy way to compute the week using the date field and views grouping?
