Starting today you can download the application Enigma Cycles. This program allows you to calculate cycles for a large number of celestial bodies and other points. You can use longitude, latitude, right ascension, declination, and distance. You can work tropical or sidereal and geocentric or heliocentric. You can calculate cycles for a period of almost 30,000 years. The results are shown on the screen and saved in a csv-file. You can show the results in charts: both a line chart of the cycle and a bar chart of the frequencies. The program is bi-lingual (English and Dutch) and has extensive online help and a user manual. The program is free and open source. More information: Enigma Cycles.
