What is Vimshottari dasha?

Vimshottari dasha is Vedic astrology's principal timing system: a fixed cycle of nine planetary periods spanning 120 years, in which each planet — Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury — governs a span of life in turn. Where you enter the cycle is set by the Moon's nakshatra at the exact moment of your birth, which is why two people born hours apart can be in different periods. Within each major period (mahadasha) run sub-periods (antardashas) of every planet in sequence. In the VivekaVeda readings, dashas are computed deterministically from ephemeris data and read for what each period favours — the work that goes well in it — rather than as prediction or threat.

How are the nine periods arranged?

The sequence and spans are fixed by the tradition, and they always sum to 120 years:

Ketu7 yearsMercury
Venus20 yearsKetu
Sun6 yearsVenus
Moon10 yearsSun
Mars7 yearsMoon

Jupiter16 yearsRahu
Saturn19 yearsJupiter

No one lives all nine in full; the point of the system is not the whole cycle but where in it you are now, and what that span favours.

Why does the Moon's position decide everything?

The zodiac divides into 27 nakshatras — lunar mansions of 13°20′ each — and every nakshatra is assigned to one of the nine period lords. The nakshatra the Moon occupies at birth names your opening period, and how far the Moon has travelled through that nakshatra sets how much of the period remains. The Moon moves roughly 13 degrees per day, crossing a nakshatra boundary about daily — so the birth time, not just the date, decides the timing map. This is one reason the VivekaVeda suite refuses to compute without an exact birth time; the mechanics are covered in how a Vedic birth chart is computed.

What does a dasha actually say — and not say?

A period names a theme, not an outcome. In the reading tradition the VivekaVeda readings follow, each period is described by what it genuinely favours: some favour expansion and visibility, some favour consolidation, depth, repair or preparation. None is read as a verdict, and none licenses fear — a challenging period is a description of the work that goes well in it, not of what will go wrong. That framing is a deliberate discipline of the suite, applied to every surface.

Where can I see my own dasha timeline?

The ₹399 classical reading names and interprets your current dasha alongside every planet, house and yoga in your chart, and the deeper readings build on the same computed timeline; the written interpretation in every reading is AI-composed from the computed chart and says so. If you want to test the system's timing first, the free proof reading on the Astrology Suite page does exactly that: it names a dated period of your past and states what the chart says it brought, for you to check against your own memory. Which reading fits which question is mapped in the choosing guide.

Common questions

What is a dasha in Vedic astrology?

A dasha is a planetary period — a span of years during which one planet's themes are held to colour life more strongly than others. Vimshottari dasha, the most widely used system, arranges nine such periods in a fixed sequence totalling 120 years.

How is my current dasha determined?

From the Moon's position at your birth. The Moon's nakshatra (one of 27 lunar mansions) fixes which planet's period you are born into and how much of it remains; the remaining periods then follow in the fixed Vimshottari sequence. This is why the exact birth time matters — the Moon moves about 13 degrees per day.

Is a difficult dasha something to fear?

No. In the reading tradition VivekaVeda follows, a period is described by what it genuinely favours — consolidation, depth, repair, preparation, expansion — not by what it threatens. Different periods favour different work; none of them is a verdict.

How long does each dasha last?

Each planet has a fixed span: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19 and Mercury 17 — 120 years in total. Within each period run sub-periods (antardashas) of every planet in the same sequence, which is how the system times at finer grain.
