Here is an astrological aspectarian software program which may prove useful to astrologers and programmers both. This program uses the Astrodienst Swiss Ephemeris (click here) to do all planetary calculations. Please see Astrodienst's web page for the details of the Swiss Ephemeris license (click here) and other documentation.

SE_Cycles generates geo and helio longitudinal and declination/latitude aspectarian data between any two given dates for all the planets and main asteroids, including exact aspects between these bodies and a specified natal chart or fixed zodiacal degree - and more (using Tropical or Sidereal zodiac). Other calculations include longitude ingresses into signs, longitudinal direction changes, declinational zero-crossings, and declinational maximum declination values.

Download SE_Cycles_v554_install.exe. Once downloaded, simply double-click on the file to install the program. The needed ephemeris files for the program are contained in the installation package.
