As the author of that post, I suppose I should chime in here... :-)

Note the difference between realtoday() (the actual date) and
today() (the date that might be today, but might be the date
specified on the command-line, or any date in the calendar-view).

For individual events, you can do

  REM MAYBE-UNCOMPUTABLE Tue AT 19:45 \
    SATISFY [$U == realtoday()] \
    MSG Main movie night

which will only show the event on Tuesday if (real)today happens to be
a Tuesday. (Thanks, Dianne, for the MAYBE-UNCOMPUTABLE which I
believe was a fairly recent addition)

For multiple events you only want to show up on the actual day, I'd
likely do something like

  IF $U == realtoday()
    # events to only show if they happen on the realtoday()
    REM Tue AT 19:45 MSG Main movie night
    REM Fri AT 20:45 MSG Aux movie night
  ENDIF

Hopefully that sheds more light on that
