Vedic Astrology has a unique system of determining the compatibility between two charts. Chart compatibility is determined by precise analysis of how the planetary positions in the charts compare and interact. Traditionally, the position of the Moon is considered the most important factor, and a scoring system based on the Moon has become very popular in India. Since the Moon is so significant for how our feelings operate, and relationships are predominantly based on feelings, there is no doubt that the Moon plays a major role. A good Moon compatibility will generally indicate a good emotional/mental fit.

There are several aspects behind a compatibility calculation like work, dominance, destiny, mental harmony, health and mutual love, but together they form an optimal situation.
