Dasha Calculator
See the Vimshottari Mahadasha and Antardasha you’re in now with their dates, the balance of your birth dasha, and every Mahadasha of your life.
Quick answer
Vimshottari dasha divides life into nine planetary periods (Mahadashas) totalling 120 years, always in the same order: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury. The first is ruled by the lord of your janma nakshatra, and how far the Moon had moved through that nakshatra sets how much of it was left at birth. Enter your birth date, time and place to see your current Mahadasha and Antardasha with dates, and your whole sequence.
The nine periods, in order
The years each graha rules, 120 in all. Your sequence starts with your janma nakshatra’s lord and runs on from there.
Frequently asked questions
What is the Vimshottari dasha?
The most widely used dasha (period) system of Jyotish, from the Brihat Parashara Hora Shastra. Nine grahas rule in turn for a fixed number of years — Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17 — 120 years in all. Jyotish reads the period you are in as the theme of that stretch of life, alongside transits.
How is my dasha calculated?
From the Moon at your birth. The lord of your janma nakshatra rules your first Mahadasha; the share of that nakshatra the Moon still had to cross is the share of the period left at birth (the balance). The rest follow in order. For example, a Moon a quarter of the way through Anuradha, ruled by Saturn, leaves three quarters of Saturn’s years.
What is an Antardasha?
Each Mahadasha is divided into nine Antardashas (bhuktis), starting with its own lord and following the same order. Each lasts in proportion to its lord’s years: in a 20-year Venus Mahadasha, the Venus Antardasha lasts 20 × 20 ÷ 120 years, about three years and four months.
Why does the dasha need my birth time?
The balance at birth comes from the Moon’s exact position, and the Moon moves about 13° a day — almost a whole nakshatra. An error of a few hours shifts every date; half a day can move them by years. With an approximate time, treat the dates as approximate too.
Which year length does this use?
The 365.25-day year counted from the exact moment of birth, as AstroSage and Jagannatha Hora do by default. Some almanacs use a 360-day year, which makes dates decades on drift by years, so check which year a source uses before comparing.
Why are my dates different on another site?
Usually because of the birth time, the ayanamsa or the year length. Aurae uses the Lahiri ayanamsa and 365.25-day years, and its dates match AstroSage’s published charts to within two days for the same birth data.
