Tara Koota: the three points that count your two birth stars against each other
Tara koota is worth 3 points out of 36. That is 8% of the whole sheet, and by weight it sits sixth among the eight kootas — five others (Yoni, Graha Maitri, Gana, Bhakoot and Nadi) all carry more. What it checks, in the classical wording, is whether the two birth stars are counted as lucky for each other, read as health and everyday luck. Not love, not money, not children. The small weather of a shared life: do the ordinary days run well when these two people are in the same house.
What it actually measures
The claim rests entirely on the Moon. Each of you was born with the Moon sitting in one of the 27 nakshatras, and the nakshatra cycle is treated like a repeating wheel of nine taras — Janma, Sampat, Vipat, Kshema, Pratyari, Sadhaka, Vadha, Mitra, Ati Mitra — counted onward from a birth star. Count from your star to your partner's star, and again from theirs back to yours. Each count lands on one of the nine. Some landings are read as supportive — Sampat, Sadhaka, Mitra, Ati Mitra. Some are read as difficult — Vipat, Pratyari, Vadha, and in some tables Janma itself, your own star echoed back.
Think of it the way you would think of two colleagues' shift schedules. Each schedule is fine on its own. The question is only what happens when you lay one over the other — do the rest days coincide, or does one person's hardest week always land on the other's? Tara koota is that overlay, done with stars.
How it is scored
Three points maximum. The common table scores it like this: both counts favourable, 3. One favourable and one difficult, 1.5. Both difficult, 0. So the koota has three rungs, not a sliding scale.
A zero needs both directions to fail at once — her count from her star to his lands on a difficult tara, and his count back to hers does too. That is a narrower condition than people fear. Roughly speaking, the difficult taras make up a third of the wheel, so both counts landing badly at once happens in something like one pair in nine. If your sheet shows a zero here, you are not a rare case. You are looking at one of the most common low scores on the whole form.
A pair where it fails
A pair calculated for these dates: she was born 23 September 1997 at 16:51 in Johor Bahru, Moon in Gemini at 4.19 degrees, nakshatra Mrigashira — the 5th of the 27 — pada 4. He was born 20 March 1988 at 21:57 in Kuala Lumpur, Moon in Aries at 10.37 degrees, nakshatra Ashwini, the 1st, pada 4.
Counted from her star, his star falls on Sadhaka — a favourable tara. Counted from his star back to hers, the count lands on Pratyari, which the tables read as difficult, the name itself carrying the sense of opposition. One side holds, one side does not. The koota scores 1.5 out of 3.
Now look at what that half-loss sat inside. Their full sheet: Varna 1.0 of 1.0, Vashya 1.0 of 2.0, Tara 1.5 of 3.0, Yoni 3.0 of 4.0, Graha Maitri 1.0 of 5.0, Gana 6.0 of 6.0, Bhakoot 7.0 of 7.0, Nadi 8.0 of 8.0. Total 28.5 out of 36 — a good score by any school’s counting. The heaviest kootas, Bhakoot and Nadi, both came through at full marks, and no dosha was flagged. The Tara shortfall is real, it is on the sheet, and it moved the total by a point and a half and no more.
A pair where it holds
A second pair, calculated for these dates: she was born 3 October 1992 at 03:02 in Kuala Lumpur, Moon in Sagittarius at 7.04 degrees, nakshatra Mula, the 19th, pada 3. He was born 26 April 1990 at 01:51 in Ipoh, Moon in Aries at 19.53 degrees, nakshatra Bharani, the 2nd, pada 2.
Here the count from her star lands on Sampat — the tara of gain — and the count from his lands on Ati Mitra, the best of the nine, the "close friend" position. Both directions favourable: 3.0 out of 3.0, full marks.
And here is the part worth sitting with. Their full sheet: Varna 1.0, Vashya 1.0, Tara 3.0 of 3.0, Yoni 2.0 of 4.0, Graha Maitri 5.0 of 5.0, Gana 0.0 of 6.0, Bhakoot 0.0 of 7.0, Nadi 8.0 of 8.0. Total 20.0 out of 36 — a low score, with both bhakoot and gana dosha flagged. Tara gave this pair everything it has to give, and the sheet still came in low, because the two heaviest kootas gave nothing. Full marks here did not rescue them there. Half marks in the first pair did not sink them. That is what 3 points out of 36 means in practice.
What a zero here does and does not mean
A zero in Tara koota means the two nakshatra counts both landed on difficult taras. That is the whole of it. It does not mean either of you is unhealthy. It does not mean the marriage will be unhappy, and it does not mean anyone should call anything off — this koota is one of eight, it controls 8% of the total, and five other kootas outweigh it. A pair can carry a zero here and still total well above the usual 18-point threshold, the way the first pair above carried their 1.5 and reached 28.5.
What the classical texts ask you to do with a Tara zero is not to panic but to look at the rest of the sheet — and beyond the sheet, at the things Guna Milan never touches: Mangal dosha, the 7th house of both charts, and the dasha periods each person is actually running. Those sit outside the 36 points entirely.
And one more thing, said plainly. The whole method rests on the Moon alone. Two people can total well above 30 on these eight kootas and still be unsuited on everything the Moon does not cover — temperament in a crisis, money habits, families, the life each one actually wants. A high number is a good Moon reading, nothing wider.
Where astrologers disagree
The tables are not uniform, and you should know it before two astrologers give you two different numbers for the same pair.
The biggest dispute is Janma tara — the count landing on the partner's own birth star position. Some tables, following the Saravali/Maitreya line, score it as neutral-to-difficult and can take a pair to zero partly on its account. Others treat Janma as acceptable and refuse to fail a pair over it. Same two charts, different verdict.
There is also disagreement over whether certain strong scores elsewhere cancel a weak Tara. Some practitioners hold that full Bhakoot or full Nadi softens a Tara dosha the way the classical exceptions soften Bhakoot and Nadi doshas themselves; others say Tara stands alone and is never cancelled, only outweighed. In my experience, the second reading is the more honest one: a small koota does not need cancelling, because it was never heavy enough to sink a match in the first place. But you will meet astrologers who read it the first way, and they are working from real texts, not inventing it.
Before any of this, check the birth times. A birth time wrong by two hours can move the Moon into the next nakshatra, and the whole Tara count is built on the nakshatra. If your mother's memory says "around midnight", the count rests on "around midnight".
Running your own
If your family has been quoted a number, run the pair yourself before the conversation goes further. The calculator at https://spacemirror.ru/en/match.html takes the two sets of birth details — date, time, place — and returns all eight kootas, the total out of 36, and any doshas, so you can see the Tara score sitting in its actual context instead of hearing one number across a table.
All eight kootas with their points, the total out of 36 and any doshas — from both Moons at their real sidereal longitude, on the time zone in force on each birth date. No sign-up.
