Not sure I read this right, but if you are talking about converting a
date to a week-number (as e.g. exhibited at the top of the weekly
agenda), this should do the trick:

;;; date is a three-element list (month day year)
;;; (calendar-current-date) returns the date in this format.
(defun week-number (date)
       (org-days-to-iso-week
                    (calendar-absolute-from-gregorian date)))

but I guess the more difficult question is a user interface that allows
you to construct such elaborate org-diary-class constructs.
