Vimshottari is the classical 120-year timing cycle of Jyotish (BPHS, chapters 46–49). It starts from your janma nakshatra: its lord rules the first mahadasha, and the nine periods follow in fixed order — Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17 years. Each mahadasha subdivides into antardashas and pratyantardashas in the same proportions. We compute the timeline with a 365.25-day dasha year, the convention used by standard Jyotish software — and the doctrine of each period is public in our knowledge base.
