horos.exe – a program for calculation of the dates of ancient zodiacs in the interval from 500 year B. C. until 2000 A.D. It is briefly described, how to use this program in the file readme.txt, and in details – in a book "New chronology of Egypt".

HOROS program uses an algorithm of calculation of heliocentric longitudes of the planets of the Solar system, created by a group of scientists: Simon J.L., Bretagnon P., Chapront J., Chapront-Touze M., Francou G., Laskar J. (Bureau des Longitudes, Paris, France). In HOROS a PLANETAP program, written by them, is used (Fortran 77). See. Astron. Astrophys. 282, 663 (1994). Locations of the moon are calculated by the theory of Chapront-Touze M., Chapront J. using the program of calculation of the Moon ephemeris ELP2000-85, version 1.0, Fortran 77 - Bureau des Longitudes, Paris, France, 1988).
Accuracy of the used algorithms at any estimates highly exceeds the accuracy, required for the calculation of zodiacs, as locations of the planets in them are given just roughly.

hor-scan.exe – a program of calculation of the ecliptical longitudes of the planets on ecliptic of the epoch of J2000, and also – their placement on the "scale of constellations" (about this scale – see the book or readme.txt) in the given time interval with a given pitch. The limits of the interval and the pitch distance will be required by the program after the start.
