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.

Vimshottari Dasha förklarade

Vimshottari Dasha — det 120-åriga vediska tidssystemet, förklarade.

Av R. Sivadas · Grundare, AstroPal · Senast uppdaterad June 2026

Vimshottari Dasha är den tidliga stöttan för vedisk astrologi. Medan födelsehoroskopet beskriver VAD livet kommer att innebära, talar dasha om NÄR. Denna sida förklarar den klassiska beräkningen, de kanoniska årstiden, de tre lagren (Mahadasha — Antardasha — Pratyantardasha) och vad varje planets period aktiverar — med ursprung i Brihat Parashara Shastra och Phaladeepika.

Vad Vimshottari Dasha är

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 kanoniska årslängderna (ändra aldrig dessa)

Vimshottari-sekvensen och årstalen är fastställda av de klassiska texterna. Varje astrolog eller verktyg som varierar dem använder inte det klassiska Vimshottari-systemet. Sekvensen är:

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. Efter Merkurius återvänder cykeln till Ketu och upprepas — även om få människor lever för att se detta hända (den andra cykeln återvänder vid 120 års ålder + första-Ketu-återstod).

Hur den initiala Mahadasha beräknas

Den första Mahadasha bestäms av nakshatran som månen befinner sig i vid födelseögonblicket. De 27 nakshatrorna är avbildade i grupper om tre på de 9 grahas:

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 vars nativmåne står i Ashwini börjar livet i Ketu Mahadasha; en vars måne står i Rohini börjar i Moon Mahadasha; och så vidare.

Den exakta startåldern — ögonblicket då nästa Mahadasha börjar — beror på hur mycket av den natala nakshatra som redan hade förflutit vid födseln. Ett barn som föds strax efter att Rohini började kommer att ha en nästan full tioårig måne-Mahadasha att leva igenom; en som föds precis innan Rohini slutar kommer bara ha några månader. Två syskon som föds av samma föräldrar vid olika tidpunkter kan därför börja vid helt olika tidpunkter i cykeln. AstroPal beräknar detta med subbågsekundprecision via Swiss Ephemeris.

De tre lagren — Mahadasha / Antardasha / Pratyantardasha

1. Mahadasha (den stora perioden)

Mahadasha är den högsta divisionen – planeten vars period dominerar 6 till 20 år av ditt liv beroende på vilken graha som går. Mahadasha sätter den övergripande färgen för det livskapitlet. En person i deras Jupiter Mahadasha lever en annan 16-årsperiod än någon i deras Mars Mahadasha — även om resten av deras horoskop är identisk.

2. Antardasha (även kallad Bhukti)

Varje Mahadasha är indelad i nio Antardashas — en för varje graha i samma Vimshottari-sekvens. Varaktigheten av varje Antardasha är proportionell: en Antardasha tar sin andel av moder-Mahadasha lika med planetens egen Vimshottari-vikt dividerat med 120. Så inom 20 år är Venus Mahadasha:

Venus-Venus Antardasha: 20 × 20/120 = 3 år 4 månader
Venus-Sol Antardasha: 20 × 6/120 = 1 år
Venus-Måne Antardasha: 20 × 10/120 = 1 år 8 månader
Venus-Mars Antardasha: 20 × 7/120 = 1 år 2 månader
...och så vidare för var och en av de 9.

Antardasha förfinar Mahadasha — den berättar vilket undertema i den löpande Mahadasha som aktiveras just nu. Venus-Saturnus antardasha inom en Venus Mahadasha är en mycket annorlunda upplevelse än Venus-Jupiter Antardasha, även om båda faller under samma övergripande Venus-kapitel.

3. Pratyantardasha (vecko-till-månad-lagret)

Varje Antardasha delas återigen in i nio Pratyantardashas enligt samma proportionella regel. Detta ger tidsmässig precision ner till veckor eller månader – den upplösning som krävs för seriös händelseförutsägelse. Utöver Pratyantardasha finns två ytterligare lager (Sookshma och Prana), men dessa konsulteras sällan utanför professionellt rekteringsarbete.

Vad varje planets Mahadasha vanligtvis aktiverar

De klassiska signaturerna, enligt Phaladeepika och BPHS. Den faktiska upplevelsen beror på planetens värdighet och husherravälde i ditt specifika horoskop — en stark, välplacerad Saturnus producerar en mycket annorlunda Saturnus Mahadasha än en plågad, försvagad.

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.

Inget av detta är förutbestämda utfall. Mahadasha är den dominerande tidsinfluensen; kartfaktorerna (planetplacering, aspekter, varga-kartor) avgör HUR den påverkan upplevs.

Hur AstroPal använder din dasha-sekvens

Varje tidsrelaterat svar i AstroPal beräknas med referens till din nuvarande Mahadasha och Antardasha. Diagrammet visar din nuvarande Mahadasha permanent högst upp i dasha-tidslinjen. Chattens åldersmedvetna livsstegslager tar hänsyn till din löpande dasha när du svarar om äktenskap, karriär, hälsa, barn eller andra tidsavgränsade frågor.

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.

Är vissa Mahadashas alltid bra och andra alltid dåliga?

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.

Vad är Sade Satis relation till 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.

Varför är cykeln 120 år och inte 100 eller 144?

Det klassiska svaret (enligt vismannen Parashara som dokumenterats i BPHS) är att 120 år är den maximala naturliga mänskliga livslängden, och proportionerna av årstidens varaktigheter kodar de relativa kosmiska vikterna för de nio grahas. Numren själva presenteras som traditionell tradition; Texterna härleder dem inte från grundprinciper. De har visat sig empiriskt konsistenta genom århundraden av observation – vilket är den klassiska standarden.

Ärlig upplysning

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.
