Dasha systems

Classical Jyotish uses multiple dasha (period) systems; choice depends on tradition and chart emphasis (Brihat Parashara surveys several).

System	Cycle	Common use
Vimshottari	120 y	General natal timing from Moon nakshatra
Yogini	36 y	Eight lunar goddesses, quick overview
Ashtottari	108 y	Sometimes when Rahu-heavy
Chara/Karaka	Jaimini	Sign-based periods from lagna
Kalachakra	Nakshatra-based	Sensitive to birth pada

Vimshottari lords by nakshatra: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury—see nakshatras. Nested sub-periods refine months and days.

This project computes Vimshottari from sidereal Moon. Pair with transits and vargas-overview for topic focus (D9 marriage, D10 career).
