Vimshottari Dasha Calculator: free, all five levels
The 120-year time-sequencing system that anchors Vedic astrology. Vidhata computes Mahadasha, Antardasha, Pratyantardasha, Sookshma and Prana periods from your Moon nakshatra, to the day.
Vimshottari dasha is the principal time-sequencing tool in Parashari Vedic astrology. The 120-year cycle distributes years across the nine grahas (Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17) and the order is fixed. Where you start in the cycle is determined by the lord of your janma nakshatra (the Moon's nakshatra at birth) and the fraction of that nakshatra already elapsed.
Each Mahadasha is subdivided into nine Antardasha periods, each Antardasha into Pratyantardasha, and so on down to Prana, five levels deep. The interaction between the Mahadasha lord and the running Antardasha lord shapes the period's character. A favourable lord-pair in their natural houses brings opportunity; a hostile pair stresses the same areas of life. Vidhata shows all five levels and how they nest.
What you get
Antardasha (sub-periods)

Pratyantardasha
Sub-sub-periods that often correspond to specific events within an Antardasha.
Sookshma and Prana
Fourth and fifth levels for fine-grained event timing.

Frequently asked questions
What is Vimshottari dasha?+
A 120-year planetary period system used in Vedic astrology to time events. Each of the nine grahas rules a fixed length of years (Ketu 7, Venus 20, Sun 6, etc.), and the sequence runs in a fixed order.
How is the starting Mahadasha determined?+
The lord of your janma nakshatra (the Moon's nakshatra at birth) determines the first Mahadasha. The fraction of the nakshatra already elapsed at birth determines how much of that Mahadasha is already done.
What are Antardasha and Pratyantardasha?+
Antardasha is a sub-period within a Mahadasha. Each Mahadasha contains nine Antardashas (one for each graha). Pratyantardasha is the next level down: sub-sub-periods within an Antardasha.
Can dasha predict exact events?+
Dasha names the timing window. The actual events depend on the natal chart, the running transits, and free will. Treat dasha as "this is the area of life under emphasis right now" rather than a literal prediction.
Why are five levels needed?+
Mahadasha (years), Antardasha (months to years), Pratyantardasha (months), Sookshma (weeks), Prana (days). Each level zooms in. For a job change, Pratyantardasha resolution is usually enough; for hour-of-day muhurat, Prana matters.
