What kind of astrology system, in your opinion, is the most accurate, and why?

As in Chinese, Western, Indian etc.

I would most likely have to say that the Indian astrology system is the most accurate and I'm basing this knowledge on the fact that the Indus River civilization is dated much older than both Western and Chinese civilizations. India has given us lots knowledge such as yoga, philosophy, primitive herb lore, also some historians credit India as inventing the zero. As far as astrological knowledge goes ancient Indian Scholars have measured the exact Circumference of the earth, all the way to the first few decimal points, much earlier than Pythagoras invented his famous theorme.

I'm actually an American of no Indian decent so my facts are entirely unbiased.

None of them, they're all guesswork.

I use western astrology, although it is not completely accurate. There should be 13 signs, as there are 13 star systems. Although the difference created is minimal, I would love to figure out how to use the original system.

USA makes more sense with the months and days...Chinese have the same sign for the whole year! That doesnt make sense but theres more to it...I like ours..

I believe they all are correct in a way.

the INDIAN SYSTEM of VEDIC ASTROLOGY is the most accurate in my experience.

None.

Astrology has no basis for it.

Out of Western and Indian astrology, I will go for Indian astrology, because we (Indians) do deep calculations where as the Western astrology lack them. I do agree that in certain area Western Astrology works to some extent.

Therefore, I will say that Indian Astrology is all most accurate but definitely NOT all Indian Astrologers.
