Yogini Dasha

What Yogini Dasha is

Yogini Dasha is a 36-year cycle of eight periods, keyed — like Vimshottari — to the nakshatra the Moon occupied at your birth. Where Vimshottari stretches nine graha periods across 120 years, Yogini compresses eight across 36.

That compression is the whole point of it. Yogini is not a rival to Vimshottari and is not read as one. It is a shorter ruler laid over the same timeline, and its appeal is that its periods are small enough to be interesting. A Vimshottari Mahadasha can cover two decades; the longest yogini period is eight years and the shortest is one.

Each period is named for a yogini — a goddess-figure with a temperament — and each yogini is assigned a graha. The names are what people quote; the grahas are what the engine computes on.

The eight yoginis

This is the tidiest table in Jyotish and it repays a second look. The yogini’s number is its length. The first runs one year, the second two, the eighth eight. There is nothing to memorise — unlike Vimshottari, where you simply have to know that Saturn gets 19 and Mercury 17. The order is the sequence and the sequence is the arithmetic.

Note also who is absent: Ketu has no yogini. Eight yoginis take eight grahas, and Ketu is the one left out. Rahu stays, as Sankata, holding the longest period of the eight.

Finding your janma yogini

There are 27 nakshatras and 8 yoginis, so the cycle does not divide the zodiac evenly — and the classical rule handles that with arithmetic rather than a lookup table:

Take the nakshatra number, add 3, divide by 8, and the remainder is your yogini. A remainder of zero means the eighth, Sankata.

Ashwini is nakshatra 1, so 1 + 3 = 4, and 4 ÷ 8 leaves 4: the fourth yogini, Bhramari, ruled by Mars. An Ashwini Moon therefore opens in a Bhramari Mahadasha. AstroShruti implements exactly this offset, so the map it uses is generated by the rule rather than transcribed from a book — which is why it cannot drift from it.

Working the rule across the zodiac gives:

Each yogini owns scattered nakshatras — one at a time, never a block — and the pattern shifts by three each time the eight-step cycle laps the 27. Because 27 is not a multiple of 8, the ring cannot close cleanly: Revati ends on Ulka (Saturn) and Ashwini restarts on Bhramari (Mars) rather than continuing to Siddha. That step is inherent to the arithmetic, not a mistake in the table.

The balance at birth

Nobody is born at the clean start of a period. The Moon sits somewhere inside its nakshatra, and the fraction of the nakshatra already crossed is the fraction of the first yogini’s period already spent.

Because each yogini owns exactly one nakshatra at a time, the sum is direct: the Moon’s position within its 13°20’ nakshatra is the elapsed fraction. If your Moon is 60% through Hasta, then 60% of Sankata’s eight years — 4 years 9 months — was gone before you were born, and your Yogini timeline opens with a balance of about 3 years 2 months of Sankata.

AstroShruti reads this off the Moon’s exact sidereal longitude and winds the first period back before the birth date by the elapsed part, so the boundaries after it land where other software puts them. And because it all hangs on the Moon’s longitude, the dates move with the ayanamsha — the same dependency that makes the KP tab’s Vimshottari differ from the Dasha tab’s.

Sub-periods

Every yogini period sub-divides into the same eight yoginis, in the same proportions, starting from the parent period’s own yogini. The rule is one proportion applied recursively:

child years = parent years × yogini years ÷ 36

So inside the eight-year Sankata Mahadasha, the Sankata antardasha runs 8 × 8/36 = 1y 9m 10d, and the Mangala antardasha inside it runs 8 × 1/36 = 2m 20d. AstroShruti drills the same five levels as Vimshottari — Maha, Antar, Pratyantar, Sookshma, Prana — and at Yogini’s scale the depth gets small quickly: a Mangala Mahadasha is one year, and its Mangala antardasha is ten days.

This is Yogini’s practical character. Vimshottari names the era; Yogini’s antardashas are short enough to point at a season.

What we do not compute

Being straight about the limits matters more than sounding complete.

• The applicability question does not arise here — and that is a real distinction. Most of the udu dashas carry a classical condition restricting the charts they suit: Ashtottari has its paksha and Rahu rules, Dwisaptati wants the Lagna lord in the 7th, Shodashottari wants a particular hora. Yogini carries no such condition, is not on AstroShruti’s conditional-dasha list, and is not flagged. If you have read our other udu-dasha pages and are expecting an advisory warning here, there isn’t one, and its absence is deliberate.
• We do not model the yoginis’ characters. Ulka and Sankata are traditionally the difficult ones, Dhanya and Siddha the benign ones. The engine computes periods, not verdicts — what Sankata actually delivers depends on where Rahu sits in your chart, and no table can shortcut that.
• The CLASSICAL/EQUAL antardasha setting does nothing to Yogini. Both options produce identical dates, because the proportional split above already is the classical rule for nakshatra dashas. If you were expecting the setting to refine these numbers, it will not.
• We do not vary the janma-yogini rule. The “+3, mod 8” offset is the common rule and the one we ship. A handful of regional texts count differently; we do not offer a variant switch for it.
• The 36-year cycle simply repeats. The timeline is generated to span at least 120 years from birth, so a short cycle wraps rather than running out. The repetition is real — the same yogini genuinely does come round again — and no distinction is drawn between a first and a third pass.

Reading Yogini in practice

Yogini is read alongside Vimshottari, not instead of it. The standard use is corroboration: when a Vimshottari antardasha and a yogini period point at the same graha in the same window, the signal is taken as stronger. When they disagree, most astrologers give Vimshottari the last word — it is the primary system, and Yogini is the overlay.

As always, the dasha opens the window and gochar tends to be what walks through it. A yogini period read without transits will usually be right about the flavour and wrong about the week.

Notes on this timeline

• The cycle totals 36 years across eight yoginis, in the fixed order above.
• Ketu is excluded; Rahu is present as Sankata with the longest period.
• The janma yogini comes from the Moon’s nakshatra, by the +3 mod 8 rule.
• The balance at birth comes from the Moon’s sidereal longitude, so the dates move with the ayanamsha.
• A dasha year is 365.2425 days, matching Jagannatha Hora and common software.
• Drilldown goes five levels: Maha → Antar → Pratyantar → Sookshma → Prana.
• Yogini is one of seventeen dasha systems the app computes, and one of the ten keyed to the Moon’s nakshatra.
