Have you got this calendar/date picker from somewhere? If you have, I would suggest that you abandon it and get a more, modern version. You could, of course, do that anyway.

If it's been created by a third party, check the documentation.

I would recommend the Dynarch calendar and there's an easy way to do just what you want using callback functions as described here (use onSelect).
