The 6th nakshatra, ruled by Rahu, 4 padas in Gemini. Four padas of 3°20′, each with its navamsa sign and naam akshar.
Ardra runs from 6°40′ Gemini – 20°00′ Gemini: 13°20′ of the ecliptic, measured sidereally from 0° Aries with the Lahiri ayanamsa. It is 4 padas in Gemini. It follows Mrigashira and is followed by Punarvasu.
Brihat Jataka, Varahamihira’s sixth-century text on the birth chart, gives each nakshatra a verse on the person born with the Moon in it. This is its verse for Ardra, in paraphrase. It reads the Moon’s nakshatra alone and, like every text of its age, speaks of a male native: your lagna, the Moon’s rashi and the rest of the kundli decide how much of it shows.
Brihat Jataka is harsh on Ardra: it says a person born with the Moon here is insincere, quick to anger and ungrateful, troublesome to others and drawn to wrongdoing. The note to the chapter in the 1885 translation adds that these results come in full only when the Moon is strong at birth.
Brihat Jataka 16.3
Each nakshatra divides into four padas of 3°20′. Each pada maps to a navamsa sign (the D9 chart is built from exactly this) and carries a naam akshar, the syllable a child born in it is named by. The Moon crosses a pada in about six hours, so it is the first thing an imprecise birth time puts in doubt.
These are classifications from the tradition rather than anything computed from the arc. They are given because kundli matching uses them, and each line says which part.
| Classification | This nakshatra | What it is used for |
|---|---|---|
| Gana | Manushya | Temperament class: Deva, Manushya or Rakshasa. Worth 6 of the 36 gun in kundli matching. |
| Yoni | Dog (female) | An animal, used for the 4-gun Yoni koota in matching. The rules are about the animals, not the people. |
| Nadi | Aadi | Aadi, Madhya or Antya. 8 gun, the largest single koota; two charts sharing one is Nadi dosha. |
Below, the matching engine scores Ardra with each of the 27 on these and on Tara.
Kundli matching counts 36 gun over eight kootas. Four of them go by the two birth nakshatras alone: Tara (3), Yoni (4), Gana (6) and Nadi (8), 21 of the 36. Below is how Ardra scores with each of the 27 on those four, by the rules the kundli matching tool uses. The other 15 gun (Varna, Vashya, Graha Maitri and Bhakoot) go by the two Moon rashis, so a pair that does well here can still lose gun there, and the other way round.
| Nakshatra | Tara | Yoni | Gana | Nadi | Total |
|---|---|---|---|---|---|
| Mrigashira | 3 | 2 | 5 | 8 | 18 |
| Swati | 3 | 2 | 5 | 8 | 18 |
| Bharani | 1.5 | 2 | 6 | 8 | 17.5 |

| Uttara Ashadha | 1.5 | 2 | 6 | 8 | 17.5 |
| Uttara Bhadrapada | 1.5 | 2 | 6 | 8 | 17.5 |
| Nakshatra | Tara | Yoni | Gana | Nadi | Total |
|---|---|---|---|---|---|
| Jyeshtha | 1.5 | 0 | 1 | 0 | 2.5 |
| Shatabhisha | 3 | 2 | 1 | 0 | 6 |
| Mula | 1.5 | 4 | 1 | 0 | 6.5 |
| Ashwini | 1.5 | 2 | 5 | 0 | 8.5 |
| Hasta | 1.5 | 2 | 5 | 0 | 8.5 |
Nadi dosha. Ardra is Aadi nadi, and so are Ashwini, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Mula, Shatabhisha and Purva Bhadrapada. With any of them the Nadi koota gives 0 of 8: that is Nadi dosha, the heaviest single loss in matching. Two people both born in Ardra share its nadi too; the dosha is treated as cancelled when their padas differ.
Gana. Ardra is Manushya gana. The lowest it scores on Gana is 1 of 6, with Krittika, Ashlesha, Magha, Chitra, Vishakha, Jyeshtha, Mula, Dhanishta and Shatabhisha.
Yoni. With Anuradha and Jyeshtha the Yoni koota gives 0 of 4: their animal and Ardra’s, the dog, are sworn enemies in the yoni table.
| Nakshatra | Tara | Yoni | Gana | Nadi | Total |

| Ashwini | 1.5 | 2 | 5 | 0 | 8.5 |

This is about days, not people. The Moon passes through Ardra once in about 27 days and stays a little over a day, and a muhurat (an auspicious time) is chosen partly by that nakshatra.
When the Moon is in Ardra, the muhurat rules allow the day for vidyarambha (starting study). They keep it out for a wedding, griha pravesh (moving into a new house), buying land or a house, buying a vehicle, opening a shop or business, joining a job, setting out on a journey, namkaran (naming a baby), mundan (the first haircut), janeu (the sacred thread), a planned operation and building work on the house.
Ardra does not make Sarvartha Siddhi yoga on any weekday.
Vimshottari dasha starts from the nakshatra the Moon was in. Ardra is ruled by Rahu, so anyone born with the Moon here begins life inside an 18-year Rahu mahadasha, but almost nobody gets the whole of it: the part remaining is the part of the nakshatra the Moon had not yet crossed.
| Moon in | From | Rahu mahadasha remaining | Of the arc still ahead |
|---|---|---|---|
| Pada 1 | 6°40′ Gemini | 18.0 – 13.5 years | 75–100% |
| Pada 2 | 10°00′ Gemini | 13.5 – 9.0 years | 50–75% |
| Pada 3 | 13°20′ Gemini | 9.0 – 4.5 years | 25–50% |
| Pada 4 | 16°40′ Gemini | 4.5 – 0.0 years | 0–25% |
The exact figure needs the Moon's degree, not just the pada: find yours, and the dasha pages carry the 120-year sequence that follows it.
Ardra’s deity is Rudra and its symbol a teardrop. Brihat Jataka gives the person born in it a verse of its own (16.3), quoted above; it reads the Moon’s nakshatra alone; the rest of the kundli decides how much of it shows.
On the four kootas that go by the nakshatras alone (Tara, Yoni, Gana and Nadi, 21 of the 36 gun), the highest are Mrigashira (18 of 21), Swati (18 of 21), Bharani (17.5 of 21), Rohini (17.5 of 21), Purva Ashadha (17.5 of 21), Uttara Ashadha (17.5 of 21) and Uttara Bhadrapada (17.5 of 21). With Ashwini, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Mula, Shatabhisha and Purva Bhadrapada it has Nadi dosha. The other 15 gun go by the two Moon rashis, so the full match needs both kundlis.
A day with the Moon in Ardra is allowed for vidyarambha (starting study), by the muhurat rules here; the tithi, weekday and season must agree too.
6°40′ Gemini to 20°00′ Gemini: 13°20′ of the sidereal ecliptic, Lahiri ayanamsa.
Rahu. Anyone born with the Moon here begins life in an 18-year Rahu mahadasha, with the part already elapsed depending on how far through the nakshatra the Moon was.
One per pada: pada 1 Ku (कू), pada 2 Gha (घ), pada 3 Ng (ङ), pada 4 Chha (छ). A child is named from the syllable of the pada the Moon was in.
Gana Manushya, yoni Dog (female), nadi Aadi. Kundli matching uses them: 6 gun for gana, 4 for yoni and 8 for nadi, out of 36.
It needs a birth time, because the Moon crosses a nakshatra in about a day. The free kundli gives you the nakshatra, the pada and the dasha that follows from it.
