This is a standard educational Ashtakoot (Guna Milan) approximation based on each partner’s Moon sign and birth star. Classical tradition includes additional nuances — regional variations in sub-scoring, and specific “dosha cancellation” exceptions for cases like matching Nadi — that aren’t modeled here. This tool is meant to help you understand the traditional framework, not as a final verdict on a real relationship. For an actual marriage decision, please consult a qualified astrologer for a complete reading, including Mangal Dosha and other factors beyond Ashtakoot.
