Nadi Dosha Calculator: Nadi Koota Check with Exceptions

Adi Nadi is the Vata group. The 9 nakshatras in it begin with Ashwini and run through Ardra, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Mula and Shatabhisha to Purva Bhadrapada. A partner whose Moon falls in Madhya or Antya Nadi scores the full 8 points with you.

Madhya Nadi is the Pitta group. Its 9 nakshatras are Bharani, Mrigashira, Pushya, Purva Phalguni, Chitra, Anuradha, Purva Ashadha, Dhanishta and Uttara Bhadrapada. A partner whose Moon falls in Adi or Antya Nadi scores the full 8 points with you.

Antya Nadi is the Kapha group. Its 9 nakshatras are Krittika, Rohini, Ashlesha, Magha, Swati, Vishakha, Uttara Ashadha, Shravana and Revati. A partner whose Moon falls in Adi or Madhya Nadi scores the full 8 points with you.

How Is It Calculated

The calculator reads the Moon's nakshatra for each person and looks up its Nadi. The 27 nakshatras follow a fixed order: Ashwini to Adi, Bharani to Madhya, Krittika to Antya. The order then reverses and repeats, so each Nadi holds 9 nakshatras.

Two different Nadis score 8 of 8, and the same Nadi scores 0 of 8 and is reported as Nadi Dosha. The calculator then runs 3 checks. They are the same nakshatra in different Moon signs, the same Moon sign in different nakshatras, and the same nakshatra in different padas. Any one of them cancels the dosha and restores the 8 points.

The 3 exceptions come from later regional practice, and the source is shown against each check. Brihat Parashara Hora Shastra does not give them. The Kundali Matching page reads the same table and the same checks, so the 2 pages always agree.

Understanding Your Result

A shared Nadi is taken to show the same constitution in both partners. The tradition reads it as a risk to health and to children. That reading belongs to the matching of the Moons alone. It says nothing about the 2 charts as a whole.

Nadi is 1 koota of 8. A match can score 8 points here and fail on Bhakoot or Gana. Another can lose these 8 and still reach a sound total. Read the koota together with the full Guna Milan score.

The 2 full charts weigh more than any koota. The 7th house, its lord, Venus and Jupiter in each chart, the navamsa and the running dashas decide how a marriage goes. When Nadi Dosha stands without an exception, have the 2 charts read together before deciding anything on this point alone.

Frequently Asked Questions

What is Nadi Dosha?

The koota of Ashtakoota matching that fails when both Moons fall in the same Nadi. Each of the 27 nakshatras belongs to Adi, Madhya or Antya Nadi. The tradition reads a shared Nadi as the same constitution in both partners and a risk to health and children. It scores 0 of 8 points unless an exception cancels it.

Which nakshatras belong to each Nadi?

Adi: Ashwini, Ardra, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Mula, Shatabhisha, Purva Bhadrapada.

Antya: Krittika, Rohini, Ashlesha, Magha, Swati, Vishakha, Uttara Ashadha, Shravana, Revati.

How many points does Nadi carry?

Eight of the thirty-six in Ashtakoota matching. A different Nadi scores all eight; the same Nadi scores none unless an exception cancels the dosha.

What cancels Nadi Dosha?

The calculator checks the same nakshatra in different Moon signs, the same Moon sign in different nakshatras, and the same nakshatra in different padas. These come from later practice, and the page names the source of each.

Does this match the Kundali Matching page?

Yes. Both pages read the same table and the same exceptions from one rule set, and a test holds them to it.

Do I need an exact birth time?

Yes. The Moon moves about 13° a day and a nakshatra is 13°20' wide, so a birth time off by hours can change the nakshatra.
