InDesign does not come with a Calender Wizard script, so you probably downloaded this elsewhere. you'll have to ask where you got it from.
(If this "lunar cycle" thing is not in the feature list of that script, chances are it's not hidden in there somewhere either. If I included such a feature, I'd make sure to advertise it. If it isn't available, you can probably contact the author and see if s/he is willing to add it.)
