Excel Sundials I have developed a number of simple Excel spreadsheet applications that can be used to design a number of sundials. I do not guarantee the accuracy of the spreadsheets and they are open to modification in any way you desire. These are available on each of the pages dealing with the particular type of sundial but they are summarized here. Please visit the appropriate sundial page for more information.Horizontal Sundial: horizontal sundial with and without longitude correction. Vertical Direct North/South Sundials: vertical direct north and south sundials with and without longitude correction. Vertical Direct East/West Sundials: vertical direct east and west sundials without longitude correction. Vertical Declining Sundial: vertical declining sundial with and without longitude correction. Polar Sundial: polar sundial without longitude correction. Analemmatic Sundial: analemmatic (human) sundial with and without longitude correction. Shadow Plane Sundial: calculations to help design a shadow plane sundial. Cycloid: calculations (by Klaus Spitz) to design a cycloid for a cycloid polar sundial.
