For example:

&%%(let* ((month (extract-calendar-month date))
          (day (extract-calendar-day date))
          (year (extract-calendar-year date))
          (last (calendar-last-day-of-month month year))
          (dayname (calendar-day-of-week date)))
     (or (and (= day last) (memq dayname '(1 2 3 4 5)))
         (and (or (= day (1- last)) (= day (- last 2)))
              (= dayname 5)))) Payday!

Or, if it's the first work day of the month:

&%%(let ((dayname (calendar-day-of-week date))
         (day (car (cdr date))))
     (or (and (= day 1) (memq dayname '(1 2 3 4 5)))
         (and (memq day '(2 3)) (= dayname 1)))) Rent due
