Hermetic Systems

Hermetic Systems has been publishing software in both English and German since July 1997. This website has two purposes: (a) to provide informative articles regarding calendars and computational subjects and (b) to make available the software developed by Peter Meyer (a professional software developer with an M.Phil. degree in computational physics). So far this software consists of over 25 Windows programs (all of which, plus the user manuals, are entirely his own work except for contributions as explicitly mentioned). These programs cover several areas of application, including calendar date conversion, word counting, encryption and other security matters, web authoring tools, text analysis, planetary aspects and mathematics.
