That's actually one of the primary points of the plugin. Check your browser console for javascript/jquery like errors. A mal-formed page or something that prohibits the associated code from executing could prevent the display of the calendar option. There are a number of other possibilities, but I'm working from the perspective that all of the related files have been loaded for the associated Zen Cart version.
