Planetary Aspects and Transits 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.
Heliocentric Planetary Aspects and Transits 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).
Your Planetary Transits YPT calculates the exact dates and times at which geocentric transits between two selected planets begin and end (relative to chosen orb values). It produces transit tables for both world (a.k.a. mundane) transits and personal transits. It supports both tropical and sidereal zodiacs.
Transits for Astro-Trading TAT produces transit tables showing the exact dates and times at which geocentric and heliocentric transits between two selected planets begin and end (relative to chosen orb values). Also allows searching for a given aspect between two planets.
