I'm trying to make it reusable by defining a function in my .emacs :

(defun diary-relative (n day)
  "Diary entry that will always appear N days from day"
  (=
   (calendar-absolute-from-gregorian date)
   (+ n (calendar-absolute-from-gregorian day))))

I try to use it with a sexp like :
<%%(diary-relative (7 '(09 15 2010)))>

which doesn't work. I really need to seriously read about lisp
programming...
