Vimshottari dasha: the great periods of your life in Vedic astrology

What is a dasha in Vedic astrology?

Dasha means “state”, “period”. The dashas are the inner clock of the Vedic chart: they show which planet plays the lead role at each stage of life. Tradition knows many systems of periods, such as the Yogini dasha or the Chara dasha of Jaimini, but the Vimshottari, “the one of one hundred and twenty”, is by far the most widely used.

The dashas do not replace transits, the passage of today’s planets over your chart: the dashas say what your chart is ready to live, the transits say when the sky sets it off. A striking transit lands more precisely when it touches the planet of the current period. The two are read together, like everything else in Vedic astrology.

The nine periods: order and length

The order never changes, and it is the order of the rulers of the nakshatras. The lengths are unequal and add up to 120 years. Here is each period, with the climate tradition gives it before any personal reading:

• Ketu, 7 years: detachment, inner search, the art of letting go of what no longer serves.
• Venus, 20 years: bonds, love, art, comfort, what holds value in your eyes.
• Sun, 6 years: your place, authority, recognition, the father figure.
• Moon, 10 years: emotions, home, the mother, contact with the public.
• Mars, 7 years: action, courage, building projects, land and property.
• Rahu, 18 years: ambition, the new, the foreign, the hunger for more. Rahu brings ideas in bursts: order is your antidote.
• Jupiter, 16 years: growth, wisdom, teachers, children, faith.
• Saturn, 19 years: effort, structure, endurance. Saturn slows things down to make them hold.
• Mercury, 17 years: learning, exchanging, writing, trading.

How is your first dasha calculated?

The starting point is the Janma nakshatra, the nakshatra of your Moon. Its ruler opens your life, but not for its full length: at birth, the Moon had already covered part of the nakshatra, and the period is already under way in the same proportion. What remains for you is the share the Moon had not yet covered.

A worked example: a Moon at 15° sidereal Taurus is in Rohini (10° to 23°20′ Taurus), a nakshatra ruled by the Moon. It has covered 5° out of 13°20′, or 37.5% of the way; 62.5% of the Moon’s 10 years remain, which is 6 years and 3 months. The rest follows in the order of the cycle:

1. Moon: from birth to 6 years and 3 months.
2. Mars: from 6 years and 3 months to 13 years and 3 months.
3. Rahu: from 13 years and 3 months to 31 years and 3 months.
4. Jupiter: from 31 years and 3 months to 47 years and 3 months.
5. Saturn: from 47 years and 3 months to 66 years and 3 months, then Mercury, Ketu, Venus, and the cycle goes on.

One hour of error in the birth time moves the Moon by about half a degree, and shifts every date of your dashas by three months to nearly a year, depending on the period. The site counts the year as 365.25 days, with the Lahiri ayanamsa.

Mahadasha and antardasha: periods within periods

The great period is called the mahadasha. It divides into nine antardashas (or bhuktis), sub-periods ruled by the same nine planets, in the same order, starting with the planet of the great period itself. The mahadasha sets the stage; the antardasha tells you which scene is being played on it.

The length of an antardasha follows a simple formula: the years of the great period times the years of the smaller one, divided by 120. In the Jupiter mahadasha (16 years), the first sub-period, Jupiter–Jupiter, lasts 16 × 16 / 120 = 2.13 years, or about 2 years, 1 month and 18 days; the next one, Jupiter–Saturn, lasts 16 × 19 / 120 = 2.53 years, or about 2 years, 6 months and 12 days. All nine together make exactly Jupiter’s 16 years.

The rule goes one level further: each antardasha divides into nine pratyantardashas, lasting from a few days to a few months. To read a sub-period, look at how the two planets get along in your chart: in the same sign, or five and nine signs apart, they cooperate; six and eight signs apart, they ask for more adjustment, and that is where effort pays off.

How do you read a period of your life?

A dasha does not just say “Saturn” or “Venus”: it says your Saturn, your Venus, with everything your chart gives them. Read the planet of the period in this order:

1. Its nature: what the planet means everywhere (Venus bonds and taste, Saturn effort and endurance, Jupiter growth).
2. Its house in the D1, counted in whole signs from the Ascendant: the area of life where the period plays out (see the houses).
3. Its rulerships: the houses whose sign it rules. For a Taurus Ascendant, Saturn rules Capricorn and Aquarius, the 9th and 10th houses: its 19-year period often revolves around vocation and career.
4. Its state in the D1: its sign (exaltation, own sign, debilitation) and the planets that join it or aspect it.
5. Its state in the D9: a planet that is solid in the Navamsha keeps its promises; when vargottama, it gains in steadiness.
6. The chart of the area: the D10 for career, the D9 for relationships, the D2 for money, as explained in crossing the charts.

Rahu and Ketu rule no sign: during their periods, they act through the ruler of the sign they occupy and the planets they join.

Climates, never sentences

A dasha describes a season, not a verdict. Saturn slows things down to make them hold: its period asks for patience and rewards what is built to last. Rahu opens an appetite for the new: it is a time to dare, and order turns momentum into results. Ketu loosens what no longer serves and opens the inner life. The periods said to be easy, Venus or Jupiter, also ask for discipline: comfort can lull.

What you do with the period matters as much as the period itself. The same Mars dasha can be the time of a project carried through or of scattered energy: the chart shows the strength available, you choose how to use it.

Your current dasha on the site

The site calculates your Vimshottari dashas from your chart. It needs your exact birth time: without it, the Vedic chart stays switched off.

1. Calculate your birth chart with your date, time and place of birth.
2. At the wheel, choose Vedic (sidereal): the D1 opens.
3. With the D1, the site gives the nakshatra of your Moon and of your Ascendant, and your dashas: the current period, then the following ones, with their dates.
4. Then open the chart of the area on your mind (D9, D10, D2…) to see how the planet of the period fares there.
