one answer

Ardra and Shatabhisha come to 11–13 of 36 with Ardra on the bride's side and 14–16 with Shatabhisha on it. What sits behind those two figures: Varna, Vashya and Tara score in full, while Nadi (0 of 8), Bhakoot (0 of 7), Gana (0 of 6), Graha Maitri (4 of 5) and Yoni (1–3 of 4) do not, and Nadi on its own accounts for 8 of the guna that go missing.

Worth stating because most matching sites imply otherwise: for Ardra and Shatabhisha the padas change nothing. Sixteen combinations, one answer. The exact minute of birth still decides plenty in a chart — it just does not decide this.

Koota by Koota

Pada 1 on each side, and what every koota is reading for Ardra with Shatabhisha. Varna and Gana are the two directional tests, which is why each name gets a column: Gana differs between them.

Ashtakoot koota scores for Ardra with Shatabhisha at pada 1 on both sides, shown separately for each partner on the bride’s side, with the values each koota reads.
Koota	Ardra bride	Shatabhisha bride	What it reads

Nadi / 8	0	0	Shatabhisha: Adi (Vata) · Ardra: Adi (Vata)
Total / 36	11–13	14–16	Below the conventional threshold

Nadi, 0 of 8 — Shatabhisha: Adi (Vata) · Ardra: Adi (Vata). The heaviest koota in the system, all or nothing.
Bhakoot, 0 of 7 — Aquarius and Gemini — 9/5. One of the three forbidden distances, and Bhakoot is all or nothing.
Gana, 0 of 6 — Shatabhisha: Rakshasa · Ardra: Manushya. Directional: swap the partners and the same two ganas score differently.
Graha Maitri, 4 of 5 — Shatabhisha: Saturn · Ardra: Mercury. Five guna ride on how the two sign lords regard each other, more than any other single test.
Yoni, 1–3 of 4 — Shatabhisha: Horse · Ardra: Dog. Not the same animal, not a hostile pair, so the graded middle.

Half-guna figures are exact rather than rounded. Each koota’s rule is set out in full on Ardra’s table and Shatabhisha’s.

All Sixteen Pada Combinations

Ardra runs Gemini 6°40′ – 20°00′ and Shatabhisha runs Aquarius 6°40′ – 20°00′ — two arcs 13°20′ wide, each divided into four padas of 3°20′, which puts the two Moons anywhere between 106°40′ and 133°20′ apart. Every cell below holds two totals: Ardra as bride first, Shatabhisha as bride second. All sixteen read alike, so the padas can be left out of this one.

Ashtakoot totals out of 36 for Ardra with Shatabhisha across all sixteen pada combinations, each cell giving Ardra as bride then Shatabhisha as bride, on the strict reading of Yoni and Vashya.
Ardra ↓ / Shatabhisha →	Pada 1Aquarius	Pada 2Aquarius	Pada 3Aquarius	Pada 4Aquarius
Pada 1Gemini	11 / 14	11 / 14	11 / 14	11 / 14
Pada 2Gemini	11 / 14	11 / 14	11 / 14	11 / 14
Pada 3Gemini	11 / 14	11 / 14	11 / 14	11 / 14
Pada 4Gemini	11 / 14	11 / 14	11 / 14	11 / 14

Strict reading of the two disputed kootas throughout. The generous reading of Yoni and Vashya adds 2 guna to every cell. None of the sixteen clears the conventional threshold of 18 on this reading. Dimmed cells fall below it; the nakshatra finder returns the pada from a birth date, time and place.

The Two Doshas, and Whether They Are Cancelled

The two heavy kootas, checked with their cancellations. Neither gives a partial score, so each is worth 8 and 7 guna outright or nothing at all.

Nadi Koota — 0 of 8

Ardra and Shatabhisha are both Adi (Vata), so the plain rule gives nothing. None of the three recognised cancellations reaches this pair — the same star in different padas, both Moons in one rashi, or two rashis sharing a lord — so the eight guna are lost and 28 is the ceiling for Ardra with Shatabhisha however well everything else goes.

Bhakoot Koota — 0 of 7 at pada 1

In every pada combination, the two Moon signs stand at one of the three forbidden distances and Bhakoot gives nothing. Neither cancellation is available — the sign lords are Mercury and Saturn, neither the same planet nor mutual friends.

A cancellation is relief, not a score adjustment — the koota still reads zero above. Remedial practice for Nadi dosha is set out on the Nadi dosha page.

Two Tests Outside the 36

The South Indian reckoning runs to ten kootas, and two of the extras are counts between Ardra and Shatabhisha alone — so they can be given here and checked by hand.

Mahendra — present. Mahendra wants every third star from the fourth — 4, 7, 10, 13, 16, 19, 22, 25 — and Ardra to Shatabhisha is 19. The two counts always add to 29, so a Mahendra pair holds whichever way round the match is made.
Stri-Dirgha — satisfied both ways. This one is directional in earnest: 19 from Ardra and 10 from Shatabhisha, against a threshold sources give as seven or as nine. It holds either way round here.

Neither test touches the 36. Muhurta nature is a different question again — Ardra is Tikshna (sharp), Shatabhisha is Chara (movable) — and it governs what each star suits doing, not who it marries.

How the Pair Ranks on Each Side

A total carries meaning against the alternatives rather than on its own, and the alternatives differ for the two stars: 14 of 36 puts Shatabhisha 26th among Ardra's 27 possible partners and Ardra 23rd among Shatabhisha's, both on the pada-1 figures those two tables print.

In Ardra’s table

26th of 27

Shatabhisha scores 14 there outright. Ardra’s 27 partners run from 5 to 29 with a median of 22.5, so this one sits below the middle of what Ardra can reach — all 27 rows.

In Shatabhisha’s table

23rd of 27

Ardra scores 14 there outright. Shatabhisha’s 27 partners run from 9.5 to 28 with a median of 21.5, so this one sits below the middle of what Shatabhisha can reach — all 27 rows.

What This Total Is Not

Across every pairing of two Moon positions that can exist, 63.6% clear 18 and the median total is 20.5, so clearing the conventional bar is the ordinary result rather than a distinction. The ceiling is 35, not 36 — no pairing of Ardra and Shatabhisha or of anything else reaches a perfect score, and a site reporting one has added something to the arithmetic.

Written rather than computed, and worth the longer read: the 36 guna taken one koota at a time and what the Navamsa adds that Guna Milan cannot. The full profiles of the two stars — deities, symbols, temperament, the syllables used for naming — are on the Ardra page and the Shatabhisha page.

Frequently Asked Questions

How many guna do Ardra and Shatabhisha score?

11–13 of 36 with Ardra as the bride and 14–16 with Shatabhisha as the bride, taking pada 1 on both sides. The padas do not change it — all sixteen combinations give the same answer, which makes this one of the 146 pairs of 351 where the two birth stars settle the score outright. The generous reading of Yoni and Vashya adds 2 guna to every cell. Against every possible pairing of two Moon positions, 63.6% clear 18 and the median is 20.5.

Are Ardra and Shatabhisha compatible?

On Ashtakoot the conservative reading puts Ardra with Shatabhisha at below the conventional threshold — under the 18 that families conventionally look for. The guna are lost on Nadi (0 of 8), Bhakoot (0 of 7), Gana (0 of 6), Graha Maitri (4 of 5) and Yoni (1–3 of 4). Read that as a filter result, not as a recommendation. A koota scoring zero — here Gana, Bhakoot and Nadi — is the part worth taking to an astrologer rather than to a calculator.

Does the pada change the result for Ardra and Shatabhisha?

No. Every one of the sixteen pada combinations returns the same total for Ardra and Shatabhisha. Neither star crosses a boundary between its padas, so all four sit in one rashi and one half of it, and no koota can move. 120 of the 351 pairs behave this way.

Do Ardra and Shatabhisha have Nadi dosha?

Yes on the plain rule: both birth stars fall in Adi (Vata), and a shared nadi scores 0 of 8 — the largest single deduction in Ashtakoot. The three recognised cancellations — the same star in different padas, both Moons in one rashi, or two rashis sharing a lord — do not apply to Ardra with Shatabhisha, so the eight guna are genuinely lost. That leaves a ceiling of 28 for this pair however well the other seven go. Across every possible pairing, 33.3% carry Nadi dosha and 23.2% of those are cancelled.

Is it better for Ardra to be the bride or the groom?

On the arithmetic, Shatabhisha on the bride's side scores higher — 14–16 against 11–13. Varna and Gana are the only kootas that can do that, and here Gana goes from 0 with Ardra as bride to 3 with Shatabhisha as bride. 314 of the 351 pairs move like this, so a calculator that takes two stars without asking who is the bride has picked a direction for you.

Run It On the Real Padas

The score is settled for Ardra and Shatabhisha, but the doshas, the seventh house and the running dasha are not — and those are what a chart is for.
