If you are an astrologer or a fan, you will know that there are two main astrology systems. And these two systems have 30° or so difference between the signs. This means you will most likely be one sun sign in tropical and another in sidereal. This also creates vastly different birth charts by the sign differences occurring in many planets.
So, you are waiting for me to tell you which is accurate? This is a theory.
Here’s it. Tropical astrology (western) birth charts are accurate personality data. These tells you your character, personality and aspirations very well. Sidereal (Vedic) astrology birth charts tell you predictions. These are mostly accurate prediction because they are based on the fixed stars. So tropical charts have a general understanding of your personality as a person, while the sidereal covers the predictive events.
Another theory is: Tropical charts signify you, while sidereal signify the energy around your birth. So I can be a Capricorn sun born around a time of Sagittarius sun energy. I can also be (among the few that fall in the middle) a Capricorn sun born around a time of Capricorn energy. This can also bring up theories of differences within a zodiac sign. Because a Capricorn-sag energy person will behave differently from a Capricorn -cap person, right?
A person also once said, if you come from Eastern countries like India, then you can stick to sidereal(Vedic) astrology. Then if you are from a western country and other countries then you can go with Tropical(western) astrology. The theory was also about different time systems and all that. Can the same argument be said about Chinese astrology? But that seems like a vastly different system, though there are similarities.
Also, here is someone else’s theory about it. Though i am not in support of this.
What do you think?
