What's the difference between Sidereal and Tropical Astrology?read more

Tropical Astrology is the method most people use in the Western world and in Asia most people use Sidereal. Tropical Astrology is based on the solstices and equinoxes. Sidereal is based on the movement of the fixed stars. The Tropical and Sidereal systems lined up around 100 A.D. Since that time there is now about a 24 degree difference between your Tropical and your Sidereal Horoscope. That's why when someone tells you 'your sign' according the the Sidereal system, it is probably one sign behind what you're used to. 'The procession of the equinoxes' is the term that describes exactly why there is this large ~24 degree difference between the Tropical and Sidereal systems.
