Read your Dasha periods as a timeline.
Dasha periods are a traditional timing framework. This explorer calculates the Vimshottari sequence from your birth Moon and shows the dates and nested periods used by your Kundli report.

Three levels, explained simply
A Mahadasha is a main period associated with a planet in the Vimshottari sequence. An Antardasha is a sub-period inside it. A Pratyantardasha is a further subdivision. These are nested intervals, so seeing two planet names together does not mean that two separate main periods overlap.
Generate your chart, then open All dashas. Expand a main period to see its Antardasha dates. The active main period and sub-period are marked, with finer period names shown for the active Antardasha. Life timeline provides a separate view of the current period and the report's interpretations.
Why the first period can begin before birth
The calculation starts with the Moon's sidereal Nakshatra. The part of that Nakshatra already traversed determines how much of the first main period is considered elapsed; the remaining part gives the balance at birth. A first-period start date before your birthday is therefore expected in this method.
This implementation uses a 120-year cycle and a 365.25-day year. It divides sub-periods proportionally using the same planet-year allocations. These are calculation conventions, and comparing dates across services requires matching those conventions as well as birth inputs.
| Planet | Years in a full main period |
|---|---|
| Ketu | 7 |
| Venus | 20 |
| Sun | 6 |
| Moon | 10 |
| Mars | 7 |
| Rahu | 18 |
| Jupiter | 16 |
| Saturn | 19 |
| Mercury | 17 |
Dates are calculated; events remain uncertain
A calculated period boundary is not a guaranteed promotion, marriage or loss. Traditional interpretation also considers placements, rulership and other factors, while real outcomes depend on circumstances and choices. Do not turn a difficult-sounding planet name into a prediction of harm.
An uncertain birth time changes the Moon's position and can shift the starting balance. A Nakshatra boundary can even change the first period's lord. With an unknown time, use the timeline as provisional and avoid fine event timing.
Before you begin.
Clear answers, so you can explore with confidence.
Does the start of a Dasha guarantee a life event?
No. The dates describe a traditional period system, not measured event probabilities. They can frame a discussion of chart factors, but they do not guarantee any particular outcome.
Why is my first Mahadasha shorter after birth?
The Moon has already travelled through part of its birth Nakshatra. This implementation treats that fraction of the associated main period as elapsed and calculates the remaining balance at birth.
