Software to calculate geocentric and heliocentric astrological aspects,
world transits, personal transits and synastry

Translate to:
These programs appeal mainly to astrologers (in particular, to followers of the work of Richard Tarnas and to others interested in world and personal planetary transits) but they are also interesting from a purely astronomical perspective.

Why pay hundreds of dollars for high-priced astrology software when for US$13.25 (€11.95 or £8.45) for a 3-month user license you can be using our informative Planetary Aspects and Transits program? Or for US$16.45 (€14.95 or £10.45) our Heliocentric Planetary Aspects and Transits program. And why spend many hours poring over ephemeris tables when for US$9.95 (€8.95 or £6.45) for a 3-month user license you can get exact dates for geocentric transits (both world and personal) using our Your Planetary Transits program? To skip the full details and just get short descriptions of these programs visit our Software Shop.

Our programs are written for Windows PCs (Windows 98 to Window 7 and 8) but will also run on Macs supporting Windows. The freely-downloadable trial versions can be made fully-functional by means of an activation key. The key can be sent immediately upon purchase (or can be obtained immediately after purchase), so there's no waiting required. Updates to new versions are free.

In addition to our software there are several articles concerning astrological aspects and transits and other astrological topics.
