This book explores an ancient technique for predicting an event according to Horary Astrology, which differs from all other predictive techniques of Classical Astrology, whether Western (Tropical) or Indian (Sidereal Zodiac).

An astrologer, using Horary Astrology, which is a completely structured system of prediction, attempts to provide an answer to a question posed at a specific moment in time, for which they construct the chart of the heavens for that moment and try to decode the available data.

As is the case with all systems, in order to achieve success in answering, the astrologer must operate scientifically, based on the absolute knowledge that governs the principles and rules of the system, without forgetting that each horoscope is a whole made up of the parts that compose it.

Thus, keeping in mind the principle of synchronicity and analogy, they perceive the connection between the question at the moment it was asked and the data of the heavens, and essentially, through the instantaneous horoscope they create, they provide the answer to the inquirer, respecting the universe, whose signs they decode.
