What Watch is a powerful tool that covers many areas and techniques of astrology. Its purpose is to get quick access to relevant information and displaying it in a concise and no-nonsense way: Keep it simple while providing all that is necessary. What Watch assumes that you're already familiar with some basics of astrology, and has an extensive tutorial explaining how to use the astrological techniques implemented here. My view on the foundations of astrology is also explained on this website.... More Info »
What Watch draws and prints chart wheels, including synastry and composite, draws tables of essential dignities, calculates element and quality balances and allows analysing birth aspects using a "harmonic aspectarian". It is also a tool for the experienced astrologer who wants to follow closely transit, progression and solar arc cycles, including transits on composite charts. The program creates ephemeris lists for any given combination of planets providing dates of the transit itself, of stations and of sign changes.
Advanced modules include search and analysis for groups of charts, a 3D globe for relocation and maps similar to Astro*Carto*Graphy. All features are explained in a built-in tutorial.
Since version 3, What Watch has an atlas and time zone conversion. Alternatively, Astrodienst offers an atlas and time zone server on their website www.astro.com that is free for private non-commercial use.
What Watch uses Swiss Ephemeris for calculations. Objects available include the Luminaries, the planets Mercury to Neptune, the dwarf planets Ceres, Pluto, Quaoar and Sedna, the centaurs Chiron, Pholus, Nessus and Asbolus, the Moon's nodes and Lilith.
What Watch can share data with other astrology programs using the Astrological Exchange Format AAF.
