Vimshottari dasha explained: your life periods in Vedic astrology
Updated 7 November 2026 · Niluna
In Vedic astrology, a dasha is a life period ruled by one planet. During that period, the matters that planet governs in your chart come forward. The most widely used system is Vimshottari dasha, a cycle of 120 years shared out among nine planets.
How long each dasha lasts
Each planet rules for a fixed number of years, always in the same order:
| Ketu | 7 years |
|---|---|
| Venus | 20 years |
| Sun | 6 years |
| Moon | 10 years |
| Mars | 7 years |
| Rahu | 18 years |
| Jupiter | 16 years |
| Saturn | 19 years |
| Mercury | 17 years |
Where your dashas begin
Your first dasha is set by the nakshatra (lunar mansion) the Moon occupied at your birth. Each of the 27 nakshatras has a ruling planet, and that planet rules your first dasha.
Because the Moon was part-way through that nakshatra when you were born, you are born part-way through the first dasha too. The portion already travelled is subtracted, which is called the balance of dasha. This is why an accurate birth date and Moon position matter so much.
Mahadasha and antardasha
Each main period (mahadasha) is divided into nine sub-periods (antardashas), one for each planet, in the same order starting with the mahadasha lord itself. A sub-period lasts in proportion to both planets: mahadasha years multiplied by antardasha years, divided by 120.
Example: in a 20-year Venus mahadasha, the Mercury antardasha lasts 20 × 17 ÷ 120 = 2.83 years, a little under 2 years and 10 months.
How to use your current dasha
- Look at which houses the dasha lord rules and occupies in your chart. Those areas of life become active.
- Notice when the antardasha changes. Many people feel the shift within weeks of the new sub-period starting.
- Plan big moves for periods whose lords are strong and well placed for that goal, and use quieter periods to prepare.
- Remember that a difficult period is a phase with an end date, not a sentence.
