Nadi Dosha Calculator: Nadi Milan Check with Cancellation Rules

What this Nadi dosha calculator checks (and why one chart is never enough)

Nadi is the last and heaviest of the eight kootas in Ashtakoot guna milan, worth 8 of the 36 points. Every one of the 27 nakshatras belongs to one of three nadis — Aadi (Vata), Madhya (Pitta) or Antya (Kapha) — and when the bride and groom share the same nadi, the pair scores 0 on this koota and the match is said to have Nadi dosha.

This free nadi dosha calculator works out each partner’s janma nakshatra from birth details (or lets you pick the nakshatra and pada directly), names the nadi of each, states whether Nadi dosha is present, and then checks the three classical cancellation rules one by one so you know whether the dosha actually stands for your pair. A single person cannot “have” Nadi dosha — it is a property of two charts together, which is why a one-person nadi lookup on its own tells you almost nothing.

The logic above is the same Nadi routine used inside the Sahita app, which runs the full 36-guna report — Varna to Nadi, plus Manglik on both sides — in 11 Indian languages. If you want the Nadi verdict alongside Bhakoot, Graha Maitri and the total score, install Sahita free from Google Play and enter both charts.

How to use this Nadi dosha calculator

1. Choose an input mode. The tool has two tabs. Use Birth details if you know the date, time and place of birth for both partners — the tool computes the Moon’s nakshatra itself. Use I know our nakshatras if you already have each partner’s janma nakshatra and pada from a kundali or from our nakshatra finder.
2. Fill in both partners. In birth-details mode, enter date, time and place (the place list covers 14,000+ Indian towns and talukas). In dropdown mode, pick the nakshatra and pada (1–4) for each person. The pada matters — one of the cancellation rules depends on it.
3. Press the button. You get each partner’s nadi (Aadi / Madhya / Antya), a Nadi Dosha yes/no tag, the Nadi koota points out of 8, and, if the nadis match, which of the three classical cancellations applies.
4. Read the cancellation line before reacting. “Nadi Dosha: Yes” followed by “Cancelled — same rashi, different nakshatra” is a very different situation from an uncancelled dosha. The line names the exact rule so you can show it to your family astrologer.

If you have the date of birth but not the time, do not guess noon. The Moon spends about a day in each nakshatra, so on most dates the nadi is the same from midnight to midnight — but not on changeover days. Our kundli matching without birth time tool computes the Moon at both ends of your time window and tells you if the nakshatra flips.

What Nadi means in Ashtakoot: 8 of 36 points

The word nadi means channel or pulse, and the three nadis are mapped to the three Ayurvedic constitutions: Aadi to Vata, Madhya to Pitta and Antya to Kapha. The classical reasoning is physiological rather than mystical — two people of the same constitution were thought to pass an unbalanced constitution to their children, and to lack the complementary temperament that steadies a household. That is why Nadi is the only koota that is either full marks or zero, with nothing in between: different nadi scores 8/8, same nadi scores 0/8.

Eight points is a lot. A pair that clears every other koota but shares a nadi tops out at 28/36, and a pair with Nadi dosha and Bhakoot dosha together cannot exceed 21/36. This is why some astrologers call an uncancelled Nadi dosha a “Maha dosha” and treat it as a stop sign regardless of the total. Our guide to Nadi dosha in kundali matching walks through where the 8 points sit in the overall scheme, and the 36 guna milan explained article covers the other seven kootas. For the neutral background, the Wikipedia entry on Ashtakoota lists all eight with their weights.

Aadi, Madhya and Antya Nadi: the full 27-nakshatra table (verified)

The nadi assignment follows a fixed rhythm through the 27 nakshatras: Aadi, Madhya, Antya, Antya, Madhya, Aadi, and then the same six-step pattern repeats. Each nadi therefore has exactly nine nakshatras. Check any table you find against that rule — several popular pages fail it.

Nadi	Constitution	Nakshatras (9 each)
Aadi (Adi)	Vata	Ashwini, Ardra, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Moola, Shatabhisha, Purva Bhadrapada
Madhya	Pitta	Bharani, Mrigashira, Pushya, Purva Phalguni, Chitra, Anuradha, Purva Ashadha, Dhanishta, Uttara Bhadrapada
Antya	Kapha	Krittika, Rohini, Ashlesha, Magha, Swati, Vishakha, Uttara Ashadha, Shravana, Revati

Two of the highest-ranking pages for this query print a Madhya row with only eight nakshatras. One drops Purva Ashadha; the other drops Purva Phalguni. Both are wrong — 27 nakshatras divided into three nadis must give nine each, and Purva Ashadha and Purva Phalguni are both Madhya (Pitta) nadi in every classical listing. If you are Purva Ashadha and your partner is, say, Chitra, a table with the missing entry would tell you there is no dosha when there is.

Sahita’s table above is the one the calculator uses. If you are not sure of your nakshatra, the nakshatra finder gives it with the pada and all the matching attributes, and the Wikipedia page on nakshatras has the full list with their lords.

Nadi dosha cancellation rules, checked one by one

Nadi dosha is not a verdict; it is a flag that triggers a second check. The Muhurta texts — Muhurta Chintamani is the one most pandits cite — list specific conditions under which two people of the same nadi may still marry. Most online tools mention that “exceptions exist” and stop there. This nadi dosha calculator runs the three rules that appear in every standard listing, in this order, and names the one that fires:

1. Same nakshatra, different pada. If both partners were born under the same nakshatra but in different padas (quarters), the dosha is held to be cancelled. Two people in Rohini pada 1 and Rohini pada 3, for instance, share Antya nadi but the dosha does not apply. This rule also covers the case where the same nakshatra falls in two different rashis (Krittika, Mrigashira, Punarvasu, Uttara Phalguni, Chitra, Vishakha, Uttara Ashadha, Dhanishta and Purva Bhadrapada each straddle a sign boundary).
2. Same rashi, different nakshatra. If both Moons are in the same sign but in different nakshatras — a Vrishabha (Taurus) groom in Krittika and a Vrishabha bride in Rohini, both Antya nadi, for example — the shared rashi is held to neutralise the shared nadi. Many texts treat this as the strongest of the three exceptions. It can only arise in six signs (Vrishabha, Mithuna, Kanya, Tula, Makara and Kumbha), because those are the only rashis that contain two nakshatras of the same nadi.
3. Same rashi lord. If the two Moon signs have the same ruling planet — Mesha and Vrishchika (both Mars), Vrishabha and Tula (both Venus), Mithuna and Kanya (both Mercury), Dhanu and Meena (both Jupiter), Makara and Kumbha (both Saturn) — the dosha is considered mitigated.

One honest note on scoring. When a cancellation applies, Sahita keeps the Nadi koota at 0/8 in the total and marks the dosha as cancelled, rather than restoring the 8 points. This matches AstroSage and most matching software, and it is the reason two reports for the same couple can differ by exactly eight points — one pandit restored the marks, the other did not. We explain that gap in app score vs astrologer score.

The full rule set with worked examples is in our Nadi dosha cancellation rules guide, and the less common ones — Rajju-based and nakshatra-lord-based exceptions that some regional traditions add — are in Nadi dosha cancellation exceptions.

To see the cancellation logic run on the whole chart at once — with the same rules applied to Bhakoot and Manglik — open Sahita on Google Play. The report prints each rule and its result for your pair.

Same nakshatra, different pada: does it cancel? And what about the same pada?

Same nakshatra, different pada

Yes — this is the first rule above and the one people search for most. Two people born under the same nakshatra always share a nadi, so the raw koota is 0/8, but the pada difference is treated as sufficient variation for the dosha not to apply. The calculator asks for pada precisely so it can test this. Note that “cancelled” does not mean “recommended”: the same-nakshatra pairing has its own considerations under Rajju and Stree Deergha in the South Indian system, and our same nakshatra marriage article goes through them.

Same nakshatra, same pada

Here the texts are stricter. Same nakshatra and same pada is the one combination where none of the three standard cancellations fires, and most Muhurta authors advise against it unless the nakshatra is on a short “permitted” list. AstroSage prints such a list — Rohini, Mrigashira, Ardra, Krittika, Pushya, Jyeshtha, Shravana, Uttara Bhadrapada, Revati — but the list varies from text to text and no page on the first page of search results says which source its version comes from.

Sahita does not apply that list automatically. If your pair lands on same nakshatra, same pada, the tool reports the dosha as uncancelled and you should take the chart to an astrologer who works in your family’s tradition rather than trust a website’s list. In the birth-details mode, it is also worth checking that the two birth times are correct, because this is the case where a boundary error matters most.

Why your birth time matters only near nakshatra boundaries

Nadi is a property of the Moon’s nakshatra, and the Moon moves about 13 degrees 20 minutes a day — roughly one nakshatra per day. So unlike the Lagna, which changes every two hours, your nadi is usually the same whatever time of day you were born.

The exception is a changeover day, when the Moon crosses from one nakshatra into the next at some point between midnight and midnight. If you were born on such a day, an hour’s error in the recorded time can move you from, say, Uttara Phalguni (Aadi) into Hasta (Aadi) with no effect on nadi — or from Hasta (Aadi) into Chitra (Madhya), which flips the entire Nadi verdict.

Practically: if the Moon’s degree on the result is within about one degree of a nakshatra edge (each nakshatra spans 13°20′), treat the nadi as sensitive and double-check the time on the hospital record. Sahita uses the Lahiri (Chitrapaksha) ayanamsa, the standard of the Indian government’s Rashtriya Panchang; a chart made with a different ayanamsa can shift the Moon by up to a degree and produce a different nakshatra near an edge. The story of a groom who changed his birth time is a reminder that the input matters as much as the rule.

Effects, folklore and remedies: Nadi Dosh Nivaran puja and Mahamrityunjaya jaap

The traditional reading is narrow: same nadi is linked to difficulty conceiving, weaker health in children, and a lack of temperamental balance between the spouses. Some texts single out Madhya (Pitta) nadi as the most severe of the three; others do not grade them. That is the full extent of the classical claim. Everything beyond it — and there is a lot beyond it online — is folklore or marketing.

Two examples from pages currently ranking for this query. One single-purpose “nadi dosh” site quotes a WHO figure of eight lakh suicides a year and implies most are caused by betrayal by a spouse, then states that Nadi dosha has no remedy and “the only solution is to abandon such relationships”. Neither claim has any basis in the Muhurta texts, which explicitly list the cancellations above, and the suicide statistic has nothing to do with nakshatras.

Another calculator page opens by saying same-nadi couples will have no problems “in most cases” and, in the next sentence, that it “might create problems” — a contradiction that tells you the page was not written by anyone who has applied the rule. Real couples’ experiences are more useful than either: read same nadi, healthy kids — a real story and the account of a mother who rejected a match over Nadi dosha before you decide what weight to give the flag.

If the dosha stands after the cancellation check and the families still wish to proceed, the traditional remedies are well defined and none of them are secret. They are only relevant when no cancellation applies, and the Sahita report says which case you are in — get Sahita in your language to see it for both charts.

• Nadi Dosh Nivaran puja. A Shanti puja addressed to the Moon and the couple’s nakshatra deities, usually performed before the wedding date is fixed. Regional versions exist in Varanasi, Ujjain and Rameswaram traditions.
• Mahamrityunjaya jaap. Recitation of the Mahamrityunjaya mantra, typically 1.25 lakh times by a group of priests on the couple’s behalf, or a smaller daily count by the couple themselves.
• Daan and vrat. Donation of grain, cloth or gold as prescribed for the nadi in question, and a Monday fast for the Moon. Our Nadi dosha remedies at home guide lists the low-cost versions families actually do.
• The best remedy is a correct reading. A good number of same-nadi pairs turn out to be cancelled by one of the three rules. Run the check before you book a puja. The wider context is in Nadi dosha meaning and remedies.

Nadi dosha vs Bhakoot vs Manglik: which matters more?

These are the three flags that stop a match in most families, and they are not the same kind of thing. Nadi and Bhakoot are kootas — they are scored inside the 36 points (8 and 7 respectively) and both have documented cancellations. Manglik dosha is outside the score entirely: it is a property of one chart (Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house) and it is checked for each partner separately, then compared. A match can score 30/36 and still be flagged Manglik on one side, and a 22/36 match can be clean on all three.

Flag	Type	Points at stake	Depends on	Cancellations	Check it
Nadi dosha	Koota (pair)	8 of 36	Both Moon nakshatras	3 classical rules	This page
Bhakoot dosha	Koota (pair)	7 of 36	Both Moon signs (2/12, 6/8, 5/9)	Same or friendly rashi lords	Bhakoot dosha calculator
Manglik dosha	Individual chart	Outside the 36	Mars’ house from Lagna, Moon, Venus	Own sign, exaltation, Jupiter aspect, both Manglik	Manglik calculator

In practice most astrologers weight an uncancelled Nadi dosha above Bhakoot, and treat Manglik as a separate gate. The kundali matching tool on this site runs all three together with the full score, and the gun milan score checker lets you see how a given total reads with and without these flags.

Frequently asked questions

Can I have Nadi dosha on my own?

No. You have a nadi — Aadi, Madhya or Antya — but Nadi dosha only exists between two charts whose nadis are the same. A page that gives you a “Nadi dosha yes/no” from one birth date is either guessing or reporting your nadi type and calling it a dosha. Use the two-partner mode of this nadi dosha calculator, or the nakshatra finder if you only want your own nadi for now.

Is Nadi dosha cancelled if we have the same rashi but different nakshatras?

Yes, under the second classical rule. It can only arise in six signs where two nakshatras share a nadi — Krittika and Rohini in Vrishabha, Ardra and Punarvasu in Mithuna, Uttara Phalguni and Hasta in Kanya, Swati and Vishakha in Tula, Uttara Ashadha and Shravana in Makara, Shatabhisha and Purva Bhadrapada in Kumbha. In those pairs the shared rashi is held to neutralise the dosha, and the calculator names the rule when it applies.

Is Madhya Nadi dosha the worst?

Some texts say so, because Madhya corresponds to Pitta and a double-Pitta pairing was thought hardest on children’s health. Other texts do not grade the three at all. In scoring terms there is no difference — same nadi is 0/8 whichever nadi it is — and the cancellation rules are identical. Treat “Madhya is the worst” as a traditional opinion rather than a scoring rule, and check the cancellations first.

Can we marry with Nadi dosha if the other gunas are high?

Many families do, especially when a cancellation applies or the total is otherwise strong. The conservative position is that an uncancelled Nadi dosha should be weighed on its own and not “averaged away” by a high score; a 28/36 with uncancelled Nadi dosha is not the same as a clean 28. What most astrologers agree on is the order of operations: check cancellations, then consider a remedy, then decide. Our kundali matching for marriage guide covers how families weigh it.

Which nakshatras are exempted from Nadi dosha?

Some sites list nakshatras — Rohini, Mrigashira, Ardra, Krittika, Pushya, Jyeshtha, Shravana, Uttara Bhadrapada, Revati — for which same-nakshatra marriage is permitted, and present this as a Nadi exemption. The list varies by text and is really a same-nakshatra rule rather than a nadi rule. Sahita applies the three universally accepted cancellations and reports everything else as uncancelled, so that you and your astrologer can apply a regional list deliberately rather than by accident.

Does this calculator work for a nadi dosh check by name?

Not directly, and deliberately so. Name-based matching reads the first syllable of the name against the Avakahada naming table to guess the nakshatra, which only works if the child was actually named by nakshatra. If that is your situation, our kundli matching by name tool shows the derived nakshatra before scoring, and you can then enter it in the dropdown mode here. Birth details are more reliable whenever you have them.
