What is the basic difference between the South Indian Astrology the North India astrology.

Answer:  Basically there is nothing much difference excepting the writing of a chart is clock-wise for the south Indians and in Northern parts of India they write the chart anti clock-wise. The entire rules are one and the same for all. In the Eastern part of India too, they write the chart map in a different way but the star, stellar and planets are the same with predictions and foretelling are of from the base/root of Vedic Astrology. Other than this, there is nothing much difference. While they star matching is taken, they consider 36 Gunas in other parts while the same is counted for 10 point matching known as Vivaha Dasa Porutham.
