Jyotish — Vedic astrology — is one of the oldest systems of knowledge in human civilisation, with roots stretching back more than 5,000 years. It is a profound tradition that has guided millions of families across South Asia and the wider world in understanding personality, timing, and compatibility.
Guna Milan, the 8-Kuta compatibility system used by VedicMatching, has been practised by Jyotish astrologers for centuries as a framework for assessing the auspiciousness of a proposed union. It is a cultural and spiritual practice, not a scientific methodology.
"The stars incline, they do not compel. Astrology offers a map — wisdom lies in how you read it, and in recognising that the map is not the territory."
— A principle widely held within the Jyotish traditionVedicMatching calculates Guna Milan scores using the following inputs and methods:
Our calculations aim to faithfully represent the traditional Ashtakoota system. However, different schools of Jyotish apply these rules differently. Traditional astrologers may weight, interpret, or apply exceptions to these rules in ways that differ from our automated calculations.
Before acting on any result from VedicMatching, please understand the following limitations:
We recommend treating VedicMatching's analysis as a starting point for reflection, not a final verdict. Specifically:
Using VedicMatching does not create a professional relationship of any kind — astrological, advisory, counselling, legal, or otherwise — between you and VedicMatching or any of its operators.
We are a technology platform that automates traditional astrological calculations. We are not astrologers, counsellors, matchmakers, or relationship advisors.
Moon positions are calculated using the Jean Meeus simplified lunar algorithm with Lahiri Ayanamsa. This method is accurate to approximately ±0.5 degrees of longitude for dates within a few centuries of the present. For the purposes of Nakshatra determination — which requires assigning the Moon to one of 27 segments of approximately 13.33 degrees each — this accuracy is generally sufficient.
However, if the Moon is near the boundary between two Nakshatras (within approximately 0.5 degrees), there is a possibility that our calculation places it in the adjacent Nakshatra from where a more precise ephemeris would place it. In such cases, we recommend verifying with a professional astrologer using Swiss Ephemeris or similar precision tools.
VedicMatching provides its astrological analyses "as is" without warranty of any kind, express or implied, including but not limited to any warranty of accuracy, completeness, fitness for a particular purpose, or non-infringement.
We make no representation that our Guna Milan scores will match those produced by any other software, website, or human astrologer. Differences in interpretation of classical rules, Ayanamsa selection, and calculation methods mean that results may legitimately vary between sources.
