Vimshottari is the most widely used dasha system in Vedic astrology, and its name comes from the Sanskrit for one hundred and twenty, the total length of one full cycle in years. The whole sequence is keyed to the nakshatra the Moon occupied at your birth. That single point decides which planet runs your first Mahadasha and how much of it remains. Once you grasp how the cycle is anchored and ordered, you can read a dasha table from any software with real understanding. This page lays out the mechanics; the quizzes below let you lock them in.
The 120-year cycle and the birth nakshatra
Each of the twenty-seven nakshatras has a ruling planet, and the same nine planets rule them in a repeating pattern. To start a chart, you find the Moon's nakshatra at birth, take its lord, and that planet runs the first Mahadasha. Because the Moon had usually already travelled part of the way through the nakshatra by birth, the first period is partial, not full. The remaining balance is calculated from how far the Moon still had to go. After that, every later period runs its complete length.
The sequence and the years
The order never changes, only the starting point does. The fixed sequence and lengths are: Ketu 7 years, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, and Mercury 17. Add those up and you get 120. So if your Moon's nakshatra lord is Venus, your life opens in a Venus Mahadasha (or its remaining balance), then moves to Sun, Moon, Mars, and onward through the list, looping back to Ketu after Mercury. Knowing this order by heart lets you sketch a rough life timeline in seconds.
How to read a dasha
Reading a dasha means more than naming the ruling planet. Look at where that planet sits in the chart, which houses it owns for your ascendant, its strength, and the friends or enemies aspecting it. Then drop into the running antardasha for finer detail. A Saturn period for one person brings steady, hard-won progress; for another it brings delay, depending entirely on how Saturn is placed. Always pair the reading with current transits before committing to timing, and keep predictions honest rather than alarming.
Key takeaways
- One full Vimshottari cycle runs 120 years across nine planetary periods.
- The cycle is keyed to the Moon's birth nakshatra; its lord runs the first (often partial) Mahadasha.
- Fixed order and years: Ketu 7, Venus 20, Sun 6, Moon 10, Mars 7, Rahu 18, Jupiter 16, Saturn 19, Mercury 17.
- Read a dasha by the ruling planet's placement, lordships, and strength, then refine with the antardasha and transits.
