Daśā (Vimśottari)
A planetary period: the Vimśottari system divides a 120-year lifespan into graha-ruled spans for timing events.
What it means
Vimśottari is the most-used daśā. Each graha rules a fixed number of years (Sun 6 … Venus 20), and the sequence starts from the lord of your birth nakshatra, with a partial first period for the portion already elapsed. Periods nest — mahādaśā, antardaśā, and finer — so an event's timing reads from the active combination.
How it's computed
dasha.ts starts from the Moon's janma nakshatra lord, computes the balance of the first mahādaśā from the Moon's traversal within that star, and lays out the 120-year cycle (365.25-day year) with contiguous nested antardaśās.

Frequently asked
- What decides my starting daśā?
- The lord of the nakshatra your Moon occupied at birth. The first period is partial — only the balance left in that star at your birth.
- What is a mahādaśā vs antardaśā?
- A mahādaśā is a major planetary period; each subdivides into antardaśās (sub-periods) ruled by the nine grahas in the same sequence.
