What is Vimshottari Dasha?

Vimshottari Dasha (Sanskrit for 'one hundred and twenty') is the principal Vedic astrological timing system. It divides a 120-year cycle across the nine grahas (Sun through Saturn, plus the lunar nodes Rahu and Ketu) in a fixed sequence with fixed year-durations. The starting point in the sequence is determined by the nakshatra the Moon occupies at birth. Each major period (Mahadasha) is then subdivided into nine sub-periods (Antardashas), and each Antardasha into nine sub-sub-periods (Pratyantardashas), forming a layered timing scaffold accurate to weeks.

What are the Vimshottari year durations?

The canonical year durations are fixed and must never be altered: Ketu 7 years, Venus 20 years, Sun 6 years, Moon 10 years, Mars 7 years, Rahu 18 years, Jupiter 16 years, Saturn 19 years, Mercury 17 years. Total: 120 years. These come from Brihat Parashara Hora Shastra and are repeated identically in Phaladeepika, Saravali, and every classical text. Any astrologer or tool that uses different durations is not following the classical Vimshottari system.

How is the starting Mahadasha determined?

By the nakshatra the Moon occupies at the moment of birth. The 27 nakshatras are mapped in groups of three to the 9 grahas: nakshatras 1, 10, 19 (Ashwini, Magha, Mula) are ruled by Ketu, so a person born under one of these starts in a Ketu Mahadasha. Nakshatras 2, 11, 20 are Venus. 3, 12, 21 are Sun. And so on. The exact starting age of the next Mahadasha is computed from how much of the natal nakshatra had elapsed at birth — this is why two people born on the same day in different cities can have very different starting points.

What does a Mahadasha activate?

A Mahadasha activates the themes of the planet whose period is running, modified by that planet's specific placement in your birth chart. The mature themes per classical tradition: Sun — authority, recognition, paternal matters; Moon — emotional life, mother, public reputation; Mars — energy, action, conflict, real estate; Mercury — communication, learning, commerce; Jupiter — wisdom, expansion, marriage, children; Venus — relationships, comfort, art, sensuality; Saturn — discipline, long-term work, slow ripening; Rahu — sudden expansion, foreign matters, ambition; Ketu — spiritual depth, separation, withdrawal. The actual experience depends on the planet's dignity and house lordships in your specific chart.

What is an Antardasha?

An Antardasha (also called Bhukti) is a sub-period within a Mahadasha. Each Mahadasha is divided into nine Antardashas — one for each graha in the same Vimshottari sequence. The duration of each Antardasha is proportional to its own Mahadasha length (so within a 20-year Venus Mahadasha, the Venus-Venus Antardasha runs about 3 years 4 months, while the Venus-Mars Antardasha runs about 1 year 2 months). The Antardasha refines the Mahadasha — it tells you which sub-theme of the running Mahadasha is active at any given moment.

What is a Pratyantardasha?

A Pratyantardasha is the third layer down — a sub-sub-period within an Antardasha. Each Antardasha is further divided into nine Pratyantardashas (again following the same Vimshottari sequence and proportional durations). The Pratyantardasha gives weeks-to-months level timing precision. Serious classical work also uses Sookshma (4th layer) and Prana (5th layer) but those are rarely consulted outside professional rectification work.

Are there other dasha systems besides Vimshottari?

Yes — Brihat Parashara Hora Shastra lists more than 30 dasha systems, including Ashtottari (108 years, used for some Moon-prominent charts), Yogini (36 years, popular in North India), Chara Dasha (Jaimini-school, based on signs not nakshatras), Kalachakra Dasha, and many more. Vimshottari is the most widely-used because BPHS gives it primacy and because empirical experience over centuries has shown it to be the most consistently reliable for events. AstroPal's primary dasha display is Vimshottari; other systems can be added in the chat by asking explicitly.

How does AstroPal use Dasha?

Vimshottari Dasha is at the core of every timing question in AstroPal. The chart shows your current Mahadasha and Antardasha (and the Pratyantardasha on click). The AI chat factors in the running dasha for every interpretive answer — when you ask about marriage timing, career change, or health windows, the system computes the answer from your dasha context. The dasha sequence is also a key input to the Compatibility module (Dasha Sandhi risk check) and the Muhurtha module (electional astrology evaluates the proposed date against the running dasha). All durations are canonical per the classical year-list.

Hva Vimshottari Dasha er

The Sanskrit word vimshottari means “one hundred and twenty” — the number of years in the full cycle. The system divides this 120-year cycle across the nine grahas (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, Ketu) in a fixed sequence with fixed durations. Each person's life maps onto this 120-year cycle starting at a specific point determined by their birth-Moon's nakshatra.

Source: Brihat Parashara Hora Shastra — the foundational Sanskrit text. The system is then repeated in Phaladeepika (Mantreshwara, ~13th c.), Saravali (Kalyana Varma), Jataka Parijata (Vaidyanatha), and every major classical authority.

De kanoniske årsperiodene (aldri endre disse)

Vimshottari-sekvensen og årslengdene er fastsatt av de klassiske tekstene. Enhver astrolog eller verktøy som varierer dem bruker ikke det klassiske Vimshottari-systemet. Rekkefølgen er:

Ketu — 7 years
Venus (Shukra) — 20 years
Sun (Surya) — 6 years
Moon (Chandra) — 10 years
Mars (Mangala) — 7 years
Rahu — 18 years
Jupiter (Guru) — 16 years
Saturn (Shani) — 19 years
Mercury (Budha) — 17 years

Totalt: 120 år. Etter Merkur vender syklusen tilbake til Ketu og gjentar seg — selv om få får oppleve dette (den andre syklusen kommer tilbake ved 120 år + første-Ketu-rest).

Hvordan start-Mahadasha beregnes

Start-Mahadasha bestemmes av nakshatraen som månen befinner seg i i fødselsøyeblikket. De 27 nakshatraene er kartlagt i grupper på tre på de 9 grahaene:

Ketu's nakshatras: Ashwini, Magha, Mula (1st, 10th, 19th).
Venus's: Bharani, Purva Phalguni, Purva Ashadha (2nd, 11th, 20th).
Sun's: Krittika, Uttara Phalguni, Uttara Ashadha (3rd, 12th, 21st).
Moon's: Rohini, Hasta, Shravana (4th, 13th, 22nd).
Mars's: Mrigashira, Chitra, Dhanishta (5th, 14th, 23rd).
Rahu's: Ardra, Swati, Shatabhisha (6th, 15th, 24th).
Jupiter's: Punarvasu, Vishakha, Purva Bhadrapada (7th, 16th, 25th).
Saturn's: Pushya, Anuradha, Uttara Bhadrapada (8th, 17th, 26th).
Mercury's: Ashlesha, Jyeshtha, Revati (9th, 18th, 27th).

En person hvis fødselsmåne sitter i Ashwini begynner livet i en Ketu Mahadasha; en hvis måne sitter i Rohini begynner i Moon Mahadasha; og så videre.

Den eksakte startalderen — øyeblikket neste Mahadasha begynner — avhenger av hvor mye av natal nakshatra som allerede hadde forløpt ved fødselen. Et barn født rett etter at Rohini begynte, vil ha en nesten full 10-årig måne-Mahadasha å leve gjennom; en som blir født like før Rohini slutter, vil bare ha noen få måneder. To søsken født av samme foreldre på forskjellige tidspunkter kan derfor starte på helt forskjellige punkter i syklusen. AstroPal beregner dette til sub-buesekunds presisjon via Swiss Ephemeris.

De tre lagene — Mahadasha / Antardasha / Pratyantardasha

1. Mahadasha (hovedperioden)

Mahadasha er den øverste divisjonen — planeten hvis periode dominerer 6 til 20 år av livet ditt, avhengig av hvilken graha som går. Mahadasha setter den overordnede fargen på det livskapittelet. En person i sin Jupiter Mahadasha lever en annen 16-årsperiode enn noen i sin Mars Mahadasha — selv om resten av horoskopet er identisk.

2. Antardasha (også kalt Bhukti)

Hver Mahadasha er delt inn i ni Antardashaer — én for hver graha i samme Vimshottari-sekvens. Varigheten av hver Antardasha er proporsjonal: en Antardasha tar sin andel av foreldre-Mahadashaen lik planetens egen Vimshottari-vekt delt på 120. Så innen 20 år, Venus Mahadasha:

Venus-Venus Antardasha: 20 × 20/120 = 3 år og 4 måneder
Venus-Sol Antardasha: 20 × 6/120 = 1 år
Venus-Måne Antardasha: 20 × 10/120 = 1 år 8 måneder
Venus-Mars Antardasha: 20 × 7/120 = 1 år 2 måneder
... og så videre for hver av de 9.

Antardasha raffinerer Mahadasha — den forteller deg hvilket undertema i den løpende Mahadasha som aktiveres akkurat nå. Venus-Saturn Antardasha i en Venus Mahadasha er en helt annen opplevelse enn Venus-Jupiter Antardasha, selv om begge faller under samme overordnede Venus-kapittel.

3. Pratyantardasha (det uke-til-måned-laget)

Hver Antardasha deles igjen inn i ni Pratyantardashaer ved bruk av samme proporsjonale regel. Dette gir tidspresisjon ned til uker eller måneder — den oppløsningen som trengs for seriøs hendelsesprediksjon. Bak Pratyantardasha ligger to lag til (Sookshma og Prana), men disse brukes sjelden utenfor profesjonelt rettsarbeid.

Hva hver planets Mahadasha vanligvis aktiverer

De klassiske signaturene, ifølge Phaladeepika og BPHS. Den faktiske opplevelsen avhenger av planetens verdighet og husherredømmer i ditt spesifikke horoskop — en sterk, velplassert Saturn produserer en helt annen Saturn Mahadasha enn en rammet, svekket en.

Sun (6 years) — authority, recognition, government matters, paternal relationships, ego maturation, self-discovery as the centre of one's life.
Moon (10 years) — emotional life, mother, public reputation, fluctuating moods, popularity, the inner life surfacing.
Mars (7 years) — energy, action, conflict, sports, real estate, surgery, courage, siblings, competitive endeavour.
Mercury (17 years) — communication, learning, commerce, intellect, writing, networks, friends, intellectual maturation.
Jupiter (16 years) — wisdom, expansion, philosophy, teachers, marriage, children, prosperity, ethical maturation. Often the most beneficial Mahadasha.
Venus (20 years) — relationships, comfort, art, sensuality, marriage, beauty, refinement. The longest Mahadasha — a substantial chunk of a life.
Saturn (19 years) — discipline, long-term work, slow ripening of effort, restrictions, structural change, hard-earned maturity. Often the most demanding Mahadasha.
Rahu (18 years) — sudden expansion, foreign matters, ambition, materialism, unconventional success, illusions, intense desire.
Ketu (7 years) — spiritual depth, separation, withdrawal, sudden cuts, mystical experience, dissolution of attachments.

Ingen av disse er skjebnebestemte utfall. Mahadasha er den dominerende tidspåvirkningen; horoskopfaktorene (planetplassering, aspekter, varga-kart) bestemmer HVORDAN denne påvirkningen oppleves.

Hvordan AstroPal bruker dasha-sekvensen din

Hvert tidsrelatert svar i AstroPal beregnes med referanse til din nåværende Mahadasha og Antardasha. Diagrammet viser din nåværende Mahadasha permanent øverst på dasha-tidslinjen. Chattens aldersbevisste livsstadie-lag tar hensyn til din løpende dasha når du svarer om ekteskap, karriere, helse, barn eller andre tidsbestemte saker.

The dasha timeline on /chart — shows your full 120-year Vimshottari sequence (paid plans), highlights the current Mahadasha, and lets you drill down into Antardashas and Pratyantardashas with classical Sanskrit names alongside English.
The AI chat — receives the full dasha sequence in its context and uses canonical year durations (Ketu 7, Venus 20, etc.) hardcoded into the system prompt so it never invents periods.
The Compatibility module — checks Dasha Sandhi risk — the dangerous transitions where one major period hands off to the next, sometimes around the wedding date.
The Muhurtha module — evaluates proposed dates against your running dasha. A wedding scheduled during a benefic dasha thrives; one during a difficult dasha faces unnecessary headwinds.

Er noen Mahadashaer alltid gode og andre alltid dårlige?

No. The reputation of “Jupiter Mahadasha is always best” or “Saturn Mahadasha is always hardest” is a popular oversimplification. The classical authorities are explicit that a planet's effect during its Mahadasha depends on (a) its natural significations, (b) its dignity in your chart (own sign, exalted, debilitated), (c) the houses it owns for your specific Lagna, (d) its aspects and conjunctions. A weak Jupiter can produce a difficult Jupiter Mahadasha; a strong Saturn produces a constructive Saturn Mahadasha.

Hva er Sade Satis forhold til dasha?

Sade Sati is Saturn's TRANSIT — the slow-moving real-time motion of Saturn through the signs around your Moon. The dasha is the natal timing scaffold. The two interact: Sade Sati during a Saturn-friendly Mahadasha is much milder than Sade Sati during a Mars or Sun Mahadasha. Both must be read together for accurate timing.

Hvorfor er syklusen 120 år og ikke 100 eller 144?

Det klassiske svaret (ifølge vismannen Parashara som registrert i BPHS) er at 120 år er maksimal naturlig menneskelig levetid, og proporsjonene av årsperiodene koder de relative kosmiske vektene til de ni grahaene. Numrene selv presenteres som mottatt tradisjon; tekstene stammer ikke fra grunnprinsipper. De har vist seg empirisk konsistente gjennom århundrer med observasjon — som er den klassiske standarden.

Ærlig åpenhet

Vimshottari Dasha is a multi-millennia documentary timing system with rigorous internal mathematics. It has not been peer-reviewed-validated as predictive of life events. We present it as the classical texts present it — a structured framework for thinking through life-timing, with canonical year durations and consistent rules — not as fate. The chart computations (planetary positions, nakshatras, dasha start-dates) are precise astronomy; the interpretations of what each period means are symbolic.
