For such situations, and to play around with reminder phrasing, 
I use wrapper functions (in a separate included file):

FSET _dayinterval(date,phrasing) iif(\
  ((date-today()) < -1),\
  abs(date-today()) + " day" + plural(date-today()) + " ago",\
  ((date-today()) == -1),\
  "yesterday",\
  ((date-today()) == 1),\
  "tomorrow",\
  ((date-today()) > 1),\
  iif(phrasing == "indaystime", "in ","") + \
  (date-today()) + \
  iif(phrasing == "indaystime", " days' time", \
      phrasing == "daysfromnow", " days from now", ""),\
  "today")

FSET _ago(date) _dayinterval(date,"indaystime")

FSET _date(date) dosubst("%w, %m %d%s%",date) + " (" + _ago(date) + ")"

FSET _wfun(x) choose(x, 21, 14, 7, 3, 2, 1, 0)

# The reminder - it nags until the rent_due date is revised to next month's:
SET rent_due '2014-12-12'
IF today() <= rent_due
  REM [trigger(rent_due)] WARN _wfun \
  MSG Rent is due [_date(rent_due)]
ELSE
  MSG Rent was due [_date(rent_due)] !!!
ENDIF
