In Hindu societies, especially in India, where arranged marriages are common, horoscope matching is the most important factor when going ahead with a marriage proposal. By matching the horoscopes of the prospective bride and groom, they will know how the stars influence their marriage and what remedial measures need to be taken to ensure eternal marital bliss. Birth details of boy and girl are required for kundli matching. The result is based on the Ashta Koota system, which calculates compatibility out of 36 points.
