WOY Function for non-calendar weeks

[Joe Chasan]

I have a process at a site that's been working fine dividing up
things based on WOY() function, which for most define a week as
Sunday through Saturday.

Now they want to redefine their work week as Monday through Sunday.  
WOY() takes no parameters but the subject date expression.  Does 
anyone have a routing already written that *efficiently* (key word
there) calculates WOY using other week start/end parameters?
