Astrology software to calculate geocentric and heliocentric aspects,
world transits, personal transits and synastry

VirusTotal says www.planetary-aspects.com is a totally clean site There are several different types of astrology software, because there are several different types of astrology. For example, not all astrology software deals with "houses", because astrology which focuses on planetary aspects and transits doesn't pay much (or any) attention to houses (of which there are seveal different systems).

Astrology software used by Vedic (Indian) astrologers uses a sidereal zodiac, whereas Western astrologers tend to use a tropical zodiac. The difference lies in the definition of 0° Aries, that is, the direction in the heavens from which the 360 degrees of the (or a) zodiac is reckoned. In Vedic astrology this is defined with reference to the fixed stars, but in Western astrology it is defined with reference to the vernal equinox.

Another difference in types of astrological software is whether it is geocentric or heliocentric. In geocentric astrology the zodiac is viewed with the Earth at the center, whereas in heliocentric astrology the Sun is at the center. Most astrological software is geocentric. Among the four programs below, two are purely geocentric, one is purely heliocentric, and one supports both types of astrology (see here).

The four programs below run under all versions of Windows from Windows XP to Windows 10. (They can be run on Macintosh computers only by use of a Windows emulator.) The downloadable trial versions can be made fully-functional by means of an activation key. The key can be sent immediately upon purchase of a user license (or can be obtained soon after). Updates to new versions are free.

For each program there is a link to PayPal and to Comecero for purchase of a perpetual (time-unlimited) user license. For all programs, a user license is also available for use of the software for 3 months or 1 year. To purchase a time-limited license, click on the program title to go to the product page and follow the Purchase link on the right.

Each day one program (it varies) is offered at 50% discount (perpetual license only) if ordering via Comecero.

To purchase via PayPal 2, 3 or 4 programs at one time with a discount of up to 40% click here.

The developer of these computational astrology programs is currently available for custom software development at an affordable rate. If interested please leave a message here.

PAT is a program to calculate geocentric aspects between planets at a given date. Also displays personal transits for a given birthdate, and synastry for two birthdates. It identifies aspect patterns (such as grand trines and yods) and supports searching for occurrences of them. It has graphical and dynamical displays (as well as tabular) which show how transits change over time, and how the position of a transiting planet changes. It supports both tropical and sidereal zodiacs.

HPAT is the heliocentric version of PAT, and does everything that PAT does (except, of course, that the Moon is not included). In addition, when searching for the occurrence of a particular aspect pattern one can ask it to search for an aspect pattern involving up to three specified planets (e.g. a grand trine involving Earth and Pluto).
