How to Interpret charts
This article attempts to provide an introduction to interpretation. It assumes you are familiar with the basics of astrology. You can also use the glossary of astrological terms in our reference section to read up on any unknown concepts.
Astrological Interpretation is subjective
Interpretation of astrological data employs the symbolic language of the planets (and other points) and their associated mythologies to describe observed correspondences between the position of planets, etc. and the actual events and experiences of everyday life. These observed correspondences are for the most part anecdotal and subjective. For example, an astrologer may have noted that most people approaching the time in life when transiting Uranus opposes their natal Uranus experience crisis situations and sudden changes. However, some people may not perceive these experiences as disruptive or may only experience them on an internal or unconscious level. Therefore there exist a range of possible interpretations for this particular transit, which can be better understood by looking at the whole chart to determine how this particular person is likely to handle and perceive such experiences at a particular time.
Astrological interpretation is holistic
The most basic (and least effective) method of astrological interpretation involves using Sun signs to analyze personality and potential. Some "newspaper" astrologers also use sun signs to determine daily predictions by assuming a standard birth time for all people born under that sign. These predictions are usually not very accurate because they lack a house system and the timing and relevancy of events can be way off. Some astrologers who predict for the masses without an accurate birth time may use Aspect Analysis to improve their predictions, eliminating the need for a house system, but this is also not as accurate as a properly constructed chart. In order to get fairly reliable predictions, potentials and psychological evaluations, it is necessary to acquire the correct birth data, cast a chart and perform a complete delineation.
