Dashas & Timing
A chart says what a life carries. A dasha says when. These are the period systems that turn a static horoscope into a timeline — Vimshottari first, and sixteen others behind it.
Vimshottari
Conditional nakshatra dashas
Ashtottari DashaAdvanced
A 108-year Moon-nakshatra cycle of eight lords, Ketu excluded. Unlike Vimshottari, each lord owns a contiguous block of three or four nakshatras — so the balance at birth prorates across the whole block.
Yogini DashaIntermediate
A 36-year Moon-nakshatra cycle of eight yoginis — Mangala, Pingala, Dhanya, Bhramari, Bhadrika, Ulka, Siddha and Sankata — running one to eight years each. Short periods, so it turns over three times in an average life.
Dwisaptati Sama DashaAdvanced
The equal dasha: 72 years, eight lords, nine years each — Ketu excluded. Sama means equal, and it is the one nakshatra dasha where no lord is favoured with a longer period than another.
Shodashottari DashaAdvanced
A 116-year Moon-nakshatra cycle of eight lords with periods stepping evenly from 11 to 18 years. Rahu is excluded — Ketu is not — making it the mirror of the eight-lord systems that drop Ketu instead.
Dwadashottari DashaAdvanced
A conditional nakshatra dasha of 112 years across eight lords — Venus is not one of them — counted backwards through the nakshatras from Revati, and classically applied when the Navamsa Lagna is owned by Venus.
Panchottari DashaAdvanced
A conditional nakshatra dasha of 105 years across seven lords — the two shadow grahas take no part — seeded at Anuradha, and classically applied when the Dwadasamsa Lagna falls in Cancer.
Shatabdika DashaAdvanced
A conditional nakshatra dasha of exactly 100 years across seven lords in doubling pairs — 5, 5, 10, 10, 20, 20, 30 — seeded at Revati and classically applied to a vargottama Lagna.
Shashtihayani DashaAdvanced
A conditional nakshatra dasha of 60 years across eight lords — and the only one of its family that assigns lords to contiguous blocks of nakshatras rather than stepping one lord per nakshatra. Classically applied when the Sun is in the Lagna.
Kalachakra DashaAdvanced
The wheel of time: a sign dasha whose nine-rasi sequence is looked up from the Moon's exact nakshatra pada, with a paramayush — a span — of 83 to 100 years rather than a fixed cycle.
Jaimini rashi dashas
Chara DashaAdvanced
The Jaimini sign dasha: twelve signs from the Lagna, forward or backward by the 9th sign's foot, each lasting however many signs it takes to reach its own lord.
Sthira DashaAdvanced
The "fixed" Jaimini rashi dasha: movable signs get 7 years, fixed signs 8, dual signs 9, running forward from the sign of the Brahma graha. A 96-year cycle that needs no counting.
Narayana DashaAdvanced
The best-known Jaimini rashi dasha. Its periods are signs, not grahas: it seeds from the stronger of Lagna and the 7th, and each sign's length is the count from that sign to its lord.
Shoola DashaAdvanced
The Jaimini longevity dasha: a flat nine years for every sign, a 108-year cycle, seeded from the stronger of Lagna and the 7th. Its seed and direction are a documented dispute, switchable in settings.
Mandooka DashaAdvanced
The "frog-leap" Jaimini rashi dasha: instead of walking the zodiac it leaps in trines, exhausting one modality quartet before jumping to the next. Durations count each sign to its lord.
Kala DashaAdvanced
The birth-time dasha: where your birth fell between sunrise and sunset decides everything. Two portions of the 120-year span, nine grahas each in natural order weighted 1 to 9.
Other dasha systems
Why a chart needs a clock
A birth chart is a single instant, and on its own it is timeless: it says a person carries a certain potential without saying when any of it arrives. The dasha systems supply the missing dimension.
The mechanism is the same across all of them. Time is divided into periods, each ruled by a planet (or, in Jaimini, a sign), and the ruler’s condition in the chart determines the character of its period. What differs is how the periods are derived and how long the cycle runs.
Vimshottari
Vimshottari is the default, and in practice the one most readings run on. It is a 120-year cycle divided among the nine grahas in fixed proportions — Venus 20 years, Sun 6, Moon 10, and so on.
Where you start in that cycle comes from the Moon’s nakshatra at birth: the nakshatra’s lord owns the first period, and the fraction of the nakshatra the Moon had already crossed is the fraction of that period already spent. This is why Vimshottari is sensitive to birth time — not as sensitive as the ascendant, but enough that a rough time gives rough dasha boundaries.
Periods nest. The Mahadasha is subdivided into Antardashas in the same proportions, those into Pratyantardashas, and so on down as far as needed. A reading typically works two or three levels deep: the Mahadasha for the chapter, the Antardasha for the year, the Pratyantardasha for the month.
The conditional systems
The other nakshatra-based dashas — Ashtottari, Yogini, Shodashottari, Dwisaptati, Dwadashottari, Panchottari, Shatabdika, Shashtihayani, Kalachakra — are conditional. Each classical text states when its system applies, usually from the birth ascendant, the Moon’s position, or whether the birth was in a particular paksha.
That is the key point about the count. Seventeen dasha systems is not seventeen rival answers; it is a library from which the chart’s own configuration picks. Applying a conditional dasha to a chart that does not meet its condition is a misuse of it, not a second opinion.
The Jaimini dashas
Chara, Sthira, Narayana, Shoola, Mandooka, Kala and Naisargika work on a different principle: the period belongs to a rashi, and its length is computed from the distance between signs rather than from a fixed table. They belong to the Jaimini framework and are read with Jaimini’s karakas and aspects, not grafted onto a Parashari reading.
A dasha alone predicts nothing
The standing rule across the tradition is that a dasha names the period and a transit picks the moment inside it. A dasha promising a result will not deliver it in a year whose transits are unrelated, and a striking transit during an unrelated dasha usually passes without event. Readings that consult one without the other overpredict in both directions.
Frequently asked questions
What is a dasha in Vedic astrology?
A planetary period. The life is divided into stretches ruled by successive planets, and the ruling planet's condition in the chart shapes what that stretch brings. It is the principal timing device in Jyotish.
How is the Vimshottari dasha calculated?
From the Moon's nakshatra at birth. The nakshatra's lord gives the first period, and how far the Moon had travelled through it decides how much of that period was already elapsed at birth. The full cycle runs 120 years.
Why are there so many dasha systems?
Because most are **conditional** — the classical texts specify when each applies, usually from the ascendant or the Moon's position. They are not seventeen competing opinions about the same chart; they are a set from which a chart's own configuration selects.
Which dasha should be used?
Vimshottari is the default in almost all modern practice and applies generally. The conditional systems apply when their stated condition is met, and the Jaimini rashi dashas belong to the Jaimini framework rather than the Parashari one.
