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 forklarede

Vimshottari Dasha — det 120-årige vediske tidssystem, forklarede.

Af R. Sivadas · Grundlægger, AstroPal · Sidst opdateret June 2026

Vimshottari Dasha er det tidsindstillede stillads for vedisk astrologi. Mens fødselshoroskopet beskriver HVAD livet vil indeholde, fortæller dashaen dig HVORNÅR. Denne side forklarer den klassiske beregning, de kanoniske årvarigheder, de tre lag (Mahadasha — Antardasha — Pratyantardasha) og hvad hver planets periode aktiverer — med henvisning til Brihat Parashara Hora Shastra og Phaladeepika.

Hvad 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 årslængder (ændr dem aldrig)

Vimshottari-sekvensen og årslængderne er fastlagt af de klassiske tekster. Enhver astrolog eller redskab, der varierer dem, bruger ikke det klassiske Vimshottari-system. Rækkefølgen 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

I alt: 120 år. Efter Merkur vender cyklussen tilbage til Ketu og gentager sig — selvom få mennesker lever længe nok til at se dette ske (den anden cyklus vender tilbage ved 120 år + første Ketu-rest).

Hvordan den begyndende Mahadasha beregnes

Den begyndende Mahadasha bestemmes af nakshatraen, som Månen befinder sig i i fødselsøjeblikket. De 27 nakshatras er kortlagt i grupper af 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, hvis fødselsmåne sidder i Ashwini, begynder livet i en Ketu Mahadasha; en hvis måne sidder i Rohini, begynder i Moon Mahadasha; og så videre.

Den præcise startalder — det øjeblik, hvor den næste Mahadasha begynder — afhænger af, hvor meget af den natale nakshatra der allerede var forløbet ved fødslen. Et barn født lige efter Rohini begyndte, vil have en næsten fuld 10-årig måne-Mahadasha at leve igennem; en født lige før Rohini ender, vil kun have få måneder. To søskende, der er født af de samme forældre på forskellige tidspunkter, kan derfor starte på helt forskellige tidspunkter i cyklussen. AstroPal beregner dette til sub-buesekunds præcision via schweizisk ephemeris.

De tre lag — Mahadasha / Antardasha / Pratyantardasha

1. Mahadasha (den store periode)

Mahadasha er den øverste division — planeten, hvis periode dominerer 6 til 20 år af dit liv afhængigt af, hvilken graha der kører. Mahadasha sætter den overordnede farve for det livskapitel. En person i deres Jupiter Mahadasha lever en anden 16-årig periode end en person i deres Mars Mahadasha — selvom resten af deres horoskop er identisk.

2. Antardasha (også kaldet Bhukti)

Hver Mahadasha er opdelt i ni Antardashas — én for hver graha i samme Vimshottari-sekvens. Varigheden af hver Antardasha er proportional: en Antardasha tager sin andel af moder-Mahadasha svarende til planetens egen Vimshottari-vægt divideret med 120. Så inden for en 20-årig Venus Mahadasha:

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

Antardasha forfiner Mahadasha — den fortæller dig, hvilket undertema i den løbende Mahadasha der aktiveres på dette specifikke tidspunkt. Venus-Saturn Antardasha i en Venus Mahadasha er en meget anderledes oplevelse end Venus-Jupiter Antardasha, selvom begge falder under samme overordnede Venus-kapitel.

3. Pratyantardasha (det uge-til-måned lag)

Hver Antardasha er igen opdelt i ni Pratyantardashas ved brug af samme proportionale regel. Dette giver tidspræcision ned til uger eller måneder — den opløsning, der kræves for seriøs hændelsesforudsigelse. Ud over Pratyantardasha ligger to yderligere lag (Sookshma og Prana), men disse konsulteres sjældent uden for professionelt korrektionsarbejde.

Hvad hver planets Mahadasha typisk aktiverer

De klassiske signaturer, ifølge Phaladeepika og BPHS. Den faktiske oplevelse afhænger af planetens værdighed og husherredømmer i dit specifikke horoskop — en stærk, velplaceret Saturn producerer en meget anderledes Saturn Mahadasha end en ramt, svækket 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 af disse er forudbestemte udfald. Mahadasha er den dominerende tidspåvirkning; horoskopets faktorer (planetplacering, aspekter, varga-horoskop) bestemmer HVORDAN denne indflydelse opleves.

Hvordan AstroPal bruger din dasha-sekvens

Hvert tidsrelateret svar i AstroPal beregnes med reference til din nuværende Mahadasha og Antardasha. Diagrammet viser din nuværende Mahadasha permanent øverst på dasha-tidslinjen. Chattens aldersbevidste livsstadie-lag tager højde for din løbende dasha, når du svarer om ægteskab, karriere, helbred, børn eller andre tidsbegrænsede emner.

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 nogle Mahadashaer altid gode, og andre altid 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.

Hvad 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 cyklussen 120 år og ikke 100 eller 144?

Det klassiske svar (ifølge vismanden Parashara, som det er registreret i BPHS) er, at 120 år er den maksimale naturlige menneskelige levetid, og proportionerne af årslængderne koder de relative kosmiske vægte af de ni grahaer. Numrene præsenteres som tradition; Teksterne udleder dem ikke fra grundprincipper. De har vist sig empirisk konsistente gennem århundreders observation — hvilket er den klassiske standard.

Ærlig åbenhed

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.
