How Antardasha duration is calculated
Each Antardasha receives a proportional share of its parent Mahadasha. The proportion comes from the Antardasha lord's traditional Vimshottari years out of the full 120-year cycle.
Because of this proportional structure, the same planet can have different Antardasha durations depending on which Mahadasha contains it.
Reading the Mahadasha–Antardasha combination
A useful interpretation considers both rulers together. The Mahadasha is the larger environment, while the Antardasha describes a more immediate phase inside it.
The two planets' natal condition and chart relationships are more informative than generic labels such as 'good planet' or 'bad planet'.
What comes after Antardasha?
Each Antardasha is divided again into Pratyantardashas. That gives a third timing level for users who need a more granular view.
MoKundli's timeline keeps the hierarchy visible so you can see the parent period while opening the next level.
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.
