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.

Wat Vimshottari Dasha is

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 canonieke jaarduur (verander deze nooit)

De Vimshottari-reeks en jaarlengtes worden vastgelegd door de klassieke teksten. Elke astroloog of hulpmiddel dat ze varieert, gebruikt niet het klassieke Vimshottari-systeem. De volgorde is:

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

Totaal: 120 jaar. Na Mercurius keert de cyclus terug naar Ketu en herhaalt zich — hoewel weinig mensen dit meemaken (de tweede cyclus keert terug op 120 + eerste-Ketu-rest).

Hoe de begin-Mahadasha wordt berekend

De beginnende Mahadasha wordt bepaald door de nakshatra die de Maan bezet op het moment van geboorte. De 27 nakshatras zijn in groepen van drie op de 9 grahas afgebeeld:

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).

Een persoon wiens geboortemaan in Ashwini zit, begint zijn leven in een Ketu Mahadasha; een waarvan de Maan in Rohini zit, begint in Maan Mahadasha; enzovoort.

De exacte beginleeftijd — het moment waarop de volgende Mahadasha begint — hangt af van hoeveel van de natal nakshatra al bij de geboorte was verstreken. Een kind dat net na het begin van Rohini wordt geboren, zal een bijna volle 10-jarige Maon Mahadasha moeten doormaken; iemand die net voor het einde van Rohini geboren wordt, zal slechts een paar maanden zijn. Twee broers en zussen die op verschillende momenten uit dezelfde ouders worden geboren, kunnen dus op totaal verschillende momenten in de cyclus beginnen. AstroPal berekent dit tot subboogseconde precisie via Swiss Ephemeris.

De drie lagen — Mahadasha / Antardasha / Pratyantardasha

1. Mahadasha (de belangrijkste periode)

De Mahadasha is de hoogste divisie — de planeet waarvan de periode 6 tot 20 jaar van je leven bepaalt, afhankelijk van welke graha er loopt. De Mahadasha bepaalt de algemene kleur van dat levenshoofdstuk. Een persoon in zijn Jupiter Mahadasha leeft een andere periode van 16 jaar dan iemand in zijn Mars Mahadasha — zelfs als de rest van zijn horoscoop identiek is.

2. Antardasha (ook wel Bhukti genoemd)

Elke Mahadasha is onderverdeeld in negen Antardasha's — één voor elke graha in dezelfde Vimshottari-sequentie. De duur van elke Antardasha is evenredig: een Antardasha neemt zijn aandeel van de moeder-Mahadasha gelijk aan het eigen Vimshottari-gewicht van die planeet gedeeld door 120. Dus binnen een 20-jarige Venus Mahadasha:

Venus-Venus Antardasha: 20 × 20/120 = 3 jaar 4 maanden
Venus-Zon Antardasha: 20 × 6/120 = 1 jaar
Venus-Maan Antardasha: 20 × 10/120 = 1 jaar 8 maanden
Venus-Mars Antardasha: 20 × 7/120 = 1 jaar 2 maanden
... enzovoort voor elk van de 9.

De Antardasha verfijnt de Mahadasha — het vertelt je welk subthema van de lopende Mahadasha op dit specifieke moment wordt geactiveerd. De Venus-Saturnus Antardasha binnen een Venus Mahadasha is een heel andere ervaring dan de Venus-Jupiter Antardasha, ook al vallen beide onder hetzelfde overkoepelende Venus-hoofdstuk.

3. Pratyantardasha (de week-tot-maand laag)

Elke Antardasha wordt opnieuw verdeeld in negen Pratyantardasha's volgens dezelfde proportionele regel. Dit geeft timingprecisie tot weken of maanden — de resolutie die nodig is voor serieuze gebeurtenisvoorspelling. Achter Pratyantardasha liggen nog twee lagen (Sookshma en Prana), maar deze worden zelden geraadpleegd buiten professioneel rectificatiewerk.

Wat de Mahadasha van elke planeet meestal activeert

De klassieke handtekeningen, volgens Phaladeepika en BPHS. De daadwerkelijke ervaring hangt af van de waardigheid en huisheerschappijen van de planeet in jouw specifieke horoscoop — een sterke, goed geplaatste Saturnus produceert een heel andere Saturnus-Mahadasha dan een getroffen, verzwakte.

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.

Geen van deze uitkomsten is voorbestemd. De Mahadasha is de dominante timing-invloed; de kaartfactoren (planeetplaatsing, aspecten, varga-kaarten) bepalen HOE die invloed wordt ervaren.

Hoe AstroPal je dasha-sequentie gebruikt

Elk tijdsgerelateerd antwoord in AstroPal wordt berekend met betrekking tot je huidige Mahadasha en Antardasha. De grafiek toont je huidige Mahadasha permanent bovenaan de dasha-tijdlijn. De leeftijdsbewuste levensfaselaag van de chat houdt rekening met je lopende dasha wanneer je antwoordt over huwelijk, carrière, gezondheid, kinderen of andere tijdsgebonden zaken.

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.

Generate your free birth chart and the dasha card displays your current Mahadasha and Antardasha. The Sanskrit graha name and English label appear together. The start and end dates are computed to the day.

Zijn sommige Mahadasha's altijd goed en andere altijd slecht?

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.

Wat is Sade Sati's relatie tot 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.

Waarom is de cyclus 120 jaar en niet 100 of 144?

Het klassieke antwoord (volgens Wijze Parashara zoals vastgelegd in BPHS) is dat 120 jaar de maximale natuurlijke menselijke levensduur is, en de verhoudingen van de jaarduur coderen de relatieve kosmische gewichten van de negen graha's. De nummers zelf worden gepresenteerd als een traditionele traditie; de teksten leiden ze niet af van eerste principes. Ze hebben empirisch consistent gebleken door eeuwen van observatie — wat de klassieke standaard is.

Eerlijke openheid

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.
