The Calendar Control is an ActiveX control (actually a file called mscal.ocx)
supplied with Microsoft Office. It is normally installed with a standard
installation of Microsoft Office Professional or Microsoft Access, but if you
can't find it on the list you will need to get hold of a copy. If you are
distributing your file, or planning to use it on more than one computer, you
will also need to make sure that the host computer has the mscal.ocx file
installed. You will find it on the CD that your copy of Microsoft Office
Professional came on, or you can download a copy from here.
