Free Sundial Software


The graphs you have seen on my other pages were created by an original program developed in Visual Basic ver 3.0.


What you get

If you are interested download the file called SUNZIP.ZIP. This file is 816,763 bytes. It is the complete program which when 'UNZIPPED' will have a SETUP.EXE file that will take care of all the 'behind the scenes' work.

This software is still in development, so PLEASE send me comments and suggestions on making it better. It is not 'finished' but I believe that it is complete enough to offer.


DISCLAIMER: I know that it works in the Windows for Workgroups ver 3.11, WIN 95, and WIN 98 and is virus free. Any problems should be brought to my attention, but the software is offered on an as is basis.


If you know a little about Visual Basic programs and setting up groups and items in the windows environment then you may download the same program called DIAL.ZIP, this zipped file contains the SUNDIALS.EXE file, the LOCATION.DAT file, the EQNOTIME.DAT file, and the SOLARDEC.DAT file. The .DAT files are data files for Location, Equation of Time, and Solar Declination. You will need to set up your own directories and copy the VBRUN300.DLL file to your windows directory. The good news is that this file is only 21,641 bytes!!


The program 'assumes' the user has a basic understanding of Sundial theory.


To date versions of this program have been sent to:

  • Italy
  • England
  • Australia
  • Germany
  • South Africa
  • Ireland
  • Spain

  • Czech Republic
  • India

PLEASE relay your comments to me (positive or negative). The only way to improve the program is to know what needs should be addressed. If you download please send me your name and where you live so I can add to the list above. This information is for my eyes only.
