What is Vimshottari Dasha?

Vimshottari Dasha is a traditional Jyotish timing framework. “Vimshottari” means 120 in Sanskrit — the system operates on a 120-year cycle that assigns periods to the 9 grahas in a fixed sequence. Practitioners interpret those periods symbolically; the system is not a reliable forecast of life events.

“The starting period and balance are calculated from the Moon's position within its birth nakshatra. The resulting timeline is part of a traditional interpretive system, not a guarantee about what will happen.”

The Moon nakshatra at birth determines which planet's Dasha you begin life in. From there, the planets follow in their fixed Vimshottari order. Each Mahadasha is further divided into 9 Antardashas (sub-periods), which are themselves divided into Pratyantar Dashas.

Why Birth Time Accuracy Matters

The starting Dasha balance is calculated from the Moon's position within its nakshatra. Birth time and location are inputs to that chart calculation; the effect of an input difference depends on the Moon's position relative to a nakshatra boundary and the calculation method. There is no universal four-minute threshold. If the recorded birth time is unknown, a noon estimate may not represent the actual chart.

Your Dasha balance is calculated from the birth-chart inputs and the astronomy implementation configured for the server. Swiss Ephemeris is used only where configured; other environments use the app's simplified implementation. We do not claim fixed arc-second accuracy.
