The honest starting point: the arithmetic is not the differentiator
Ashtakoot Guna Milan is a fixed classical procedure. It reads two Moon positions, performs eight lookups against tables that have not changed in centuries, and adds the results. AstroSage does this correctly. So do we. So does any competent implementation.
That means the usual comparison framing — whose calculation is more accurate — is close to meaningless here. With complete birth details for both people, a well-built tool will land on the same total as any other, give or take differences in ayanamsa and in which dosha cancellations each chooses to apply automatically.
What genuinely differs is the reporting layer: what a tool does with incomplete input, and how much of its own uncertainty it shows you. That is the axis this page compares on, because it is the one where the choice actually matters.
Where AstroSage is the better choice
We would rather say this plainly than bury it, because a comparison that only flatters the author is worth nothing to a reader trying to decide.
- Breadth of free traditional calculators. AstroSage's tool library is larger than ours and has been maintained for well over a decade. If you want Ashtakavarga, varga charts, Sarvatobhadra, Muhurta tables and a dozen other classical instruments in one place, it is the stronger library and it is not close.
- No account, no friction. Its matching runs without a login. For a one-off check that is a real advantage, and we would not pretend otherwise.
- Hindi-first and regional coverage. Its Hindi interface and regional-language reach are more mature than ours, which matters for the audience most likely to be doing kundli milan in the first place.
- Works well on constrained connections. Lightweight pages that load on slow networks are a genuine engineering achievement and a genuine user benefit.
- Institutional familiarity. Many families and astrologers have used it for years. Handing a relative a format they already recognise has real practical value.
If any of those are what you need, use AstroSage. That is a sincere recommendation, not a rhetorical concession.
Where we differ: what happens when the birth time is missing
This is the situation most families are actually in. Both dates are known; nobody wrote down the hours.
The mathematics is unforgiving and applies equally to every tool. The Moon moves roughly 13.2° per day. A nakshatra spans 13°20′. Those two numbers are almost identical, so on very nearly every date the Moon occupies two different nakshatras at some point during the day. Four of the eight kootas — Tara, Yoni, Gana and Nadi, worth 21 of the 36 points — are computed from the nakshatra and are therefore genuinely undetermined without a birth time.
A rashi, by contrast, spans 30°. A 13.2° daily sweep usually stays inside one sign, so the four sign-derived kootas — Varna, Vashya, Graha Maitri and Bhakoot, worth 15 points — survive a missing time about 56% of the time.
Most matching forms, ours and others', will accept a date without a time and return a number anyway, by assuming noon. Sometimes that assumption is right. On the nakshatra layer it is close to a coin flip, and Nadi alone — the single largest koota at 8 points — turns on it.
Our position is that the assumption should be visible. We state which kootas your inputs can reach and which they cannot, rather than presenting a partial result with the confidence of a complete one. That is a reporting choice, not a computational advantage, and we would encourage you to apply the same test to any tool you use, including ours.
What we do not do automatically, and why
Two disclosures, since a comparison page is exactly where a vendor is tempted to omit them.
We apply no automatic Nadi dosha cancellation. Classical sources describe several exceptions — same nakshatra with different rashis, same rashi with different nakshatras, shared nakshatra lords, and others. Our engine does not apply any of them. A same-nadi pairing scores zero and is flagged. This is deliberate: the exception lists are not unanimous across authorities, and a calculator that silently picked one tradition's list would be making a consequential interpretive decision and hiding it inside a number. We show the flag and say that recognised exceptions exist, so you can raise it with an astrologer who can name which authority they follow.
We assess Manglik from the Lagna only. Some traditions also check Mars from the Moon and from Venus, which can produce a different verdict. We use the Lagna reference and say so rather than implying broader coverage.
We also apply the shared-ruler Bhakoot cancellation, which restores the full 7 points when both Moon signs share a ruling planet. Exactly three sign pairs qualify: Mesha with Vrishchika, Vrishabha with Tula, and Makara with Kumbha.

What neither tool can tell you
- Whether a marriage will last. The 18 / 24 / 28 thresholds are conventions from classical and matchmaking practice with no outcome dataset behind them — nobody has followed a large cohort of matched couples and measured what happened.
- Anything outside the Moon. Ashtakoot reads the Moon sign and the nakshatra. The Sun, Venus, Jupiter, the Lagna, the houses and the dashas are all absent from the 36 points.
- The things marriages actually turn on — money, children, consent, how two people treat each other under pressure. No koota examines any of them.
- A missing birth time. That is not a paid feature on any platform. Rectification can narrow the window from dated life events, but it produces an estimate with a stated confidence, not a recovered fact.
Frequently asked
Is AstroSage kundli matching accurate?
Its planetary calculations are sound — AstroSage has run an established ephemeris for well over a decade and its Guna Milan arithmetic follows the standard Ashtakoot rules. The 36 points are the same eight lookup tables everywhere. What varies between tools is not the arithmetic but what happens when your birth details are incomplete.
What is better than AstroSage for kundli matching?
Nothing computes the 36 points better, because the computation is fixed classical tables. AskSoma differs in reporting: it states which kootas your inputs can and cannot reach, and refuses to print a nakshatra-derived score when no birth time was supplied. If you want breadth of free traditional calculators, AstroSage remains the stronger library.
Can I do kundli matching without birth time on AstroSage?
Most matching forms will accept a date and produce a score, typically by assuming a time. The mathematical problem is universal: the Moon travels about 13.2° a day against a 13°20′ nakshatra, so the nakshatra changes on very nearly every date. That makes Tara, Yoni, Gana and Nadi — 21 of the 36 points — genuinely undetermined without a birth time.
Do AskSoma and AstroSage give the same Guna Milan score?
With complete birth details for both people, they should agree closely — both use the standard Ashtakoot tables and a sidereal ayanamsa. Small differences can arise from ayanamsa choice or from which dosha cancellations a tool applies automatically. AskSoma applies the shared-ruler Bhakoot cancellation and deliberately applies no automatic Nadi cancellation.
Is AstroSage free for kundli matching?
Yes, its core matching is free and does not require an account, which is a genuine advantage. The 36-point calculation costs essentially nothing to run — eight table lookups on two Moon positions — so any complete version of it should be free on any platform.
