Dialmaker DialMaker

DIALMAKER is a free sundial design program. It lets you graphically design your sundial given a number of parameters, including the latitude of the site, the type of sundial (horizontal or vertical), the orientation of the receiving surface (for a vertical dial, equator-facing or not), and whether the sundial has to work in solar or in standard time. Visit the DialMaker page for more details and download.
