To use the program for Tibetan astrology it is absolutely indispensable to buy the Tibetan Calendar from Shang Shung Edizioni since this contains all the necessary data about the specific days, to be feed into the program.
This program will give you the most important astrological constellations for a specified day, according to the explanations given by Namkhai Norbu Rinpoche in his book "Il Chiave". The program however will not explain in any way the backgrounds or details of the Tibetan astrological system. To have a more complete understanding of this system, it is recommended to consult this book also, since there will be more details which are not given here (e.g. about the nature of the days of the week etc.).
