Mahadasha durations
The traditional full durations are fixed within the Vimshottari system, but the first Mahadasha shown from birth may be shorter because only its remaining balance is active.
- 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
What a Mahadasha does and does not tell you
In Jyotish interpretation, the Mahadasha ruler becomes an important timing influence, but its results are not read from the planet's name alone. Its sign, house ownership, natal placement, relationships and divisional-chart context all matter.
This is why two people in the same planetary Mahadasha can experience very different themes.
Why Antardasha matters
Every Mahadasha contains all nine planetary Antardashas. The active Antardasha changes the immediate combination, so a long Mahadasha can contain very different phases.
MoKundli therefore shows the active path rather than presenting only the Mahadasha ruler.
Frequently asked questions
How can I find my current Mahadasha, Antardasha and Pratyantardasha?
Vimshottari Dasha starts from the Moon's birth Nakshatra. A calculator uses birth date, accurate time, location and a defined ayanamsa to produce the Mahadasha, Antardasha, Pratyantardasha, Sookshma and Prana date ranges. Check the calculation settings when websites disagree.
Are Shani, Rahu or Ketu Dashas always negative?
No. Traditional interpretations consider the planet's house placement, dignity, lordship, aspects, conjunctions and the running sub-periods. Saturn may symbolize discipline, Rahu unusual opportunities and Ketu detachment; none guarantees a good or bad event.
Use astrology as context, not certainty
Jyotish is interpretive. A chart or Dasha period does not guarantee a particular life event. Important decisions should also use real-world evidence and appropriate professional advice.
