A Program for Exploring Astrological Aspects and Transits
Planetary Aspects and Transits is Windows software designed to help students of astrology (both amateur and professional) to explore world transits (aspects formed over time by moving planets) and personal transits (aspects formed over time by a moving planet to a planet in the natal chart). It has many user-selectable options, such as the ability to choose your preferred zodiac, set aspect orbs, and show only the outer planets.

After entering a date and time you can view the corresponding world transits in either tabular or graphical 'chart' form, showing how many aspects of each kind (square, trine, etc.) are present, and also if any aspect patterns (T-square, kite, yod, etc.) are present. You can search for aspect patterns from the currently-entered date onwards. The chart may be animated so that the development of transits can be viewed in steps of a day, a week, a month or a year.
You can also enter two birth dates, and from these get tabular and graphical displays for natal aspects (the horoscope), for personal transits (the aspect relations of the natal planets and the planets at a given date) and for synastry (the aspect relations for the two birth dates). The display of personal transits can also be animated, so as to see when aspects and aspect patterns form and subside for someone born at a certain date.
Additional information of interest to the serious astrologer is given regarding when transits start and end, and their duration. In the case of personal transits this information is displayed graphically for the entire course of the transit, showing when the transit becomes exact, or at least reaches a minimum.
All charts can be saved as PNG graphics files, with either black or white background.
Astrology is based on either the tropical zodiac or the sidereal zodiac; this software allows you to choose your preferred zodiac. It has both tabular and graphical output. Here is an example of its graphical output:
Lines joining planets show aspects, colored as at right. Colors and orbs are user-selectable. (The "av." value is explained here.)
Clicking on the 'Display table' button produces a tabular representation which provides detailed information about the aspects shown in the chart, as below:
An 'r' following the longitude of a planet indicates that the planet is retrograde (in this example, Saturn). An angle value shows difference of the aspect from exactness (so 0°0' is exact). A '-' or '+' shows whether the aspect is decreasing ('-') or increasing ('+') at the date and time shown, or in other words, whether the aspect is applying ('-') or separating ('+').

Author and acknowledgements: This software was inspired by reading Richard Tarnas's book Cosmos and Psyche, and was developed by Peter Meyer in March-July 2010. Thanks to Hank Friedman for suggestions which he made in October 2010 for significant improvements. The Moon was added in April 2011. Ecliptic longitudes have been validated by comparison with the JPL Horizons ephemerides. Longitudes of the Sun and the planets from Mercury to Neptune are calculated using a translation into C by Peter Meyer of FORTRAN routines which were originally written by astronomer Robert van Gent based on algorithms given in P. Bretagnon & J.-L. Simon, Planetary Programs and Tables from -4000 to +2800 (Willmann-Bell Inc., Richmond, 1986).
