Dasha calculator: Vimshottari and Yogini

Enter your birth details to see your dasha timeline: each mahadasha (major period), its antardashas (sub-periods) and their pratyantardashas (the third level), with the periods running today at the top. Choose the 120-year Vimshottari system or the 36-year Yogini system. Both start from the Moon's nakshatra at birth.

How the Vimshottari timeline is built

The nine lords run in a fixed order: Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19 and Mercury 17 years, which total 120. The Moon's sidereal nakshatra gives the first lord. Ashwini starts with Ketu and the lords repeat every nine nakshatras.

At birth you have already used part of that first nakshatra, so only the rest of its dasha is left. That remaining part is shown as the balance.

Within each mahadasha, the antardashas follow the same order, starting with the mahadasha lord. Each lasts (mahadasha years × its own years) ÷ 120. Pratyantardashas divide each antardasha the same way, starting with the antardasha lord.

How the Yogini timeline is built

Yogini dasha has eight periods, each named after a yogini and ruled by a graha: Mangala 1 year (Moon), Pingala 2 (Sun), Dhanya 3 (Jupiter), Bhramari 4 (Mars), Bhadrika 5 (Mercury), Ulka 6 (Saturn), Siddha 7 (Venus) and Sankata 8 (Rahu), which total 36 years. Ketu has no yogini.

To find the first yogini, add 3 to the number of the birth nakshatra (Ashwini is 1) and divide by 8. The remainder gives the yogini, with a remainder of 0 counting as Sankata. So Ardra (6) starts with Mangala and Ashwini (1) starts with Bhramari. The balance at birth comes from the part of the nakshatra still to run, as in Vimshottari. Sub-periods last (period years × own years) ÷ 36.

Because the cycle is only 36 years, it repeats more than three times within the 120 years shown.

Limits

The tool goes three levels deep: mahadasha, antardasha and pratyantardasha. It does not show the fourth and fifth levels (sookshma and prana), which last only days or hours and would need a birth time accurate to the minute. Years are 365.25 days; some software uses a 360-day year instead, so its dates can drift by months over a long period. Dates are shown in the UTC offset you entered.

The result depends on the birth time and the ayanamsa you choose. See the birth chart for the Moon position, and the method page for the formulas.
