Birth chart compatibility (Vedic synastry)
birth_chart_compatibilityRead-onlyIdempotent
Use this when someone asks whether two people are compatible in Vedic astrology, for synastry, or to compare two birth charts ("are we compatible", "compare my chart with my partner’s", "Vedic compatibility for me and my husband"). Returns each person’s Moon, Venus and Mars signs (and rising sign with a time), how the two Moon signs sit to each other, where each person’s Sun, Moon, Mars and Venus land in the other’s houses, and the strongest links between their planets. It gives no score and no verdict, and it is not the 36-point guna milan of kundli matching: say so if asked for gunas. Needs both dates and towns of birth; times make it exact. The first person is usually the one asking.
