How accurate is the horoscope?

planet's influence

The horoscope is a map associated with each individual. Its drawing starts from the moment he is born. 

At that moment, the sky and the planets have a certain position that determines energies that will influence the course of the newborn

It is obvious that over time, the stars change their positions relative to each other, so the sky map from this moment is not identical to the one that was two hours before. Consequently, planets' influence are also different

In conclusion, a horoscope is all the more accurate the more precisely the dates of birth (time and place) are provided. If the data is not very precise, and the horoscope has some deviations, not very important
