Vimshottari Dasha Explained: The 120-Year Cycle, Antardashas and How Periods Are Read

Two people can have similar horoscopes and live very different decades, because a birth chart shows what a life contains and the dasha system shows when each part of it speaks. Of the many dasha systems in Jyotisha, the one used almost everywhere in India today is Vimshottari, the cycle of 120 years divided among the nine grahas.

This guide explains what the Vimshottari dasha is, how your own sequence is decided at birth, how a Mahadasha divides into antardashas, how astrologers actually read a period, and when remedies are advised. Each of the nine periods also has its own guide, linked at the end.

What a dasha is

A dasha (దశ) is a planetary period: a stretch of years ruled by one graha, during which that graha's promise in your chart is delivered. The word means 'state' or 'condition', and that is closer to what it describes than 'phase'. The graha does not become stronger or weaker during its dasha; it simply gets the floor. What it then says depends entirely on where it sits in your chart, which houses it owns, and how well placed it is.

Vimshottari means 'one hundred and twenty'. The system divides that span among the nine grahas in fixed shares, always in the same order, and the order never changes: Ketu, Sukra, Surya, Chandra, Kuja, Rahu, Guru, Shani, Budha, and then Ketu again.

How your own sequence is decided

Your place in the cycle is fixed by the janma nakshatra — the star the Moon occupied at the moment of birth. Each of the 27 nakshatras is ruled by one of the nine grahas, three stars each, and the dasha running at birth is that of your birth star's lord.

1. The Moon's position at birth is calculated, giving the nakshatra and the pada (quarter) within it.
2. The lord of that nakshatra gives the Mahadasha you are born into. Someone born in Rohini, Hasta or Shravana, for example, is born in the Moon's period.
3. Only the balance of that period remains. It is worked out from how much of the nakshatra the Moon had still to travel: a Moon a quarter of the way through a star ruled by Jupiter leaves three-quarters of Jupiter's sixteen years, that is twelve years, still to run.
4. After that, the periods follow in the fixed Vimshottari order for the rest of the life.

Antardashas and the levels below

A Mahadasha of sixteen or twenty years is too long to read as one thing, so each is divided into nine antardashas (sub-periods, also called bhukti), one for each graha, beginning with the Mahadasha lord itself and then following the same fixed order. The share each receives is its own dasha length out of 120.

The antardasha is where most of what people call "a good year" or "a hard year" is actually read. A benefic Mahadasha with a difficult antardasha gives a rough patch in a good decade; a difficult Mahadasha with a friendly antardasha gives relief inside a long haul. The longest single sub-period in the whole cycle is Venus inside Venus, at 3 years 4 months; the shortest is the Sun inside the Sun, at 3 months 18 days.

How a dasha is actually read

Knowing which dasha runs is the easy part. What it will mean takes four more questions, and this is why two people in the same Mahadasha have nothing in common:

• Which houses does the dasha lord own in your chart? A graha delivers the affairs of the houses it rules. Jupiter is the great benefic, but for a Taurus ascendant it owns difficult houses, and its period is read accordingly.
• Where does it sit, and with whom? Its house, sign, strength, and the grahas it is joined to or aspected by. A debilitated dasha lord and an exalted one give very different sixteen years.
• What is the antardasha? The sub-period lord's own placement and its relationship with the Mahadasha lord decide the texture of each stretch within the period.
• What is transiting? Dashas say when a result is due; transits say when it lands. Saturn's transit over the natal Moon, the Sade Sati, is the one most often felt, and it has its own guide.

When remedies are advised

Tradition does not prescribe remedies for every period. They are advised when the dasha lord is weak, debilitated, combust or afflicted in the chart, when it owns the difficult houses, or when a hard antardasha and a hard transit fall together. Three things are then usually named, in this order: japam for the graha, daanam in your name, and a shanti where several grahas are involved.

1. 1.Read the period before remedying it

   The dasha table alone does not say whether a remedy is needed. A chart consultation reads the dasha, the strength of its lord and the running transits together, and only then advises the graha, the japam count and the daanam.

2. 2.Japam for the dasha lord

   Mantra japam for the graha whose period runs, performed by purohits with the sankalpam in your name and gotram. Our guide to graha japam and daanam explains what is done and why the counts differ between grahas.

3. 3.Repeat through the hard stretches

   Where a period is long, families often repeat a smaller japam or a weekly daanam through the difficult antardashas rather than performing one large remedy at the start.
