36 Guna Milan: a clear guide to Ashtakoota

When families in North India speak of "kundli milan" or "gun milan", they usually mean Ashtakoota — the eight-part ("ashta" = eight, "koota" = aspect) comparison of two birth charts. Each part carries a fixed number of points, and together they add up to 36 gunas. This guide explains what each part looks at, how to read the total, and — just as important — what the total cannot tell you.

What Ashtakoota compares

Ashtakoota is based almost entirely on the Moon at the time of birth: the Moon sign (rashi), the Moon's nakshatra (one of 27 lunar mansions of 13°20′ each) and, for one koota, the exact degree. In Vedic tradition the Moon represents the mind and emotions, which is why it is used for matching. The positions are calculated in the sidereal zodiac, which differs from the Western (tropical) zodiac by about 24° today — so your Vedic Moon sign is often not your "newspaper" sign.

The eight kootas

The kootas are listed from smallest to largest. Notice that the last three — Gana, Bhakoot and Nadi — together carry 21 of the 36 points.

Each koota has its own page with the full tables we use, the traditional meaning, common questions and related exceptions.

How to read the total

The total is grouped into traditional bands. These are labels, not predictions:

Many families treat 18 as a customary minimum. That custom is worth understanding, but it is a convention, not a law of nature. Two couples can both have 22 points and very different pictures: one may have lost points in small kootas spread across the table, the other may have a Nadi dosha with a traditional exception that applies.

Why the score isn't everything

• The total hides the detail. Which kootas lost points, and why, matters more than the sum. Our report always shows the koota-by-koota breakdown with the total.
• Doshas are read separately. Bhakoot and Nadi doshas, and Manglik status, are traditionally considered on their own, alongside the score.
• Traditions differ. Tables for Vashya, Yoni and Gana vary between sources, and so do the exceptions. Two calculators can give different totals for the same people; our methodology lists every choice we make.
• It is one input, not a verdict. A low score is not proof that a marriage will struggle, and a high score is not a guarantee. Values, communication, family expectations and mutual respect are not measured by any koota.

Traditional exceptions (parihar)

Tradition recognises that some doshas are cancelled in particular situations. For example, a Bhakoot dosha is traditionally considered cancelled when both Moon signs have the same lord (rule BHK-C1), and a Nadi dosha when both Moons are in the same sign but different nakshatras (NAD-C1). Our report checks each rule and shows it as applies, does not apply or not computable. The 36-point total itself is never changed — the exception is shown next to it, so you can see both. Read the full list in dosha cancellation, and the separate Manglik rules in the Manglik dosha guide.

Why birth-time accuracy matters

The Moon moves about 13° a day, so it changes nakshatra roughly once a day and sign roughly every two and a half days. That is why:

• With an exact time, we compute once and warn you if the Moon is very close to a boundary.
• With an approximate time (for example ±30 minutes), we scan the whole window. Each koota and dosha is marked stable if it is the same throughout, or may change with the possible values and the time when it would change. We never turn this into a percentage.
• With an unknown time, items based on the Lagna (ascendant), such as the Lagna part of the Manglik check, are shown as not computable. Moon-based kootas are stable only if the Moon stays in the same nakshatra and sign all day. We never silently assume noon.

If you only know the name, name-based matching is possible using the traditional syllable chart, but it is always labelled low confidence.

Numerology is separate

You may also see Mulank, Bhagyank and the Lo Shu grid on our site. These belong to numerology, a different system. We keep it in its own section; it never changes the guna score.

A sensible way to use the result

1. Look at the total and the koota breakdown together.
2. Check whether any dosha is present, and whether a traditional exception applies.
3. Check how confident the result is, given the birth-time accuracy.
4. Talk openly with each other and with family about what matters to you.
5. If you would like a personal reading, consult a qualified astrologer you trust — no remedy has to be bought.
