Why do the 9 planetary periods have different lengths?

The Vimshottari system assigns a fixed number of years to each of the 9 grahas (e.g. Saturn 19 years, Mercury 17 years, Ketu 7 years) that together add up to a 120-year cycle -- these fixed durations come from classical Vedic astrological texts.

Why does my starting Dasha depend on my Nakshatra?

Vimshottari Dasha calculation begins from the ruling planet of your natal Moon's Nakshatra at birth, with an initial "balance" period based on exactly how far the Moon had progressed through that Nakshatra at the moment of birth.

Frequently Asked Questions

Common questions about calculations, assumptions, and edge cases.

A Mahadasha is a major planetary period (ranging from 6 to 20 years depending on the planet) within the 120-year Vimshottari cycle; each Mahadasha is further divided into shorter Antardasha (sub-period) segments ruled by different planets.
