TARA Horary Astrology software - version 1.1

Tara is a Windows program (working on Windows 95 and later versions) designed for horary astrology according to the experience of Maurice McCann (1938-2011). It calculates all the special rules like refranation, frustration, prohibition, translation, collection, en indicates them in the horoscope wheel and aspect grids. This frees the astrologer from many hours of tedious work. A graphic ephemeris shows the evolution of longitude aspects (normal and antiscia) and declination aspects. A search function to find exact aspect moments and ingresses is also included. The help file contains numerous examples of interpreting question horoscopes. Data are saved in Paradox compatible tables.

They are scientifically applied to the chart with little “esoteric” astrological knowledge.

In the majority of cases, “yes” answers are a result of:

“No” answers are usually caused by the fact that there are:

It becomes clear that Horary Astrology, with its defined rules, is a suitable starting point for those who wish to de-mystify astrology as a whole. All that is needed to incorporate Horary Astrology into your life is a basic knowledge of planetary aspects and the required set of rules.
