The planetary period system

Dasha means "planetary period" in Sanskrit. Vedic astrology uses the Vimshottari Dasha system — a 120-year cycle divided among 9 planets. Whichever planet rules the period you are born into shapes the themes of that chapter of your life.

Three levels

Mahadasha — The major period. Lasts 6–20 years depending on the planet. Sets the overall theme of that life chapter.

Antardasha — The sub-period within a Mahadasha. Usually lasts months to a few years. Adds a secondary planetary flavour.

Pratyantardasha — The sub-sub-period. Lasts weeks to months. Useful for precise event timing.

Mahadasha durations

Sun — 6 years

Moon — 10 years

Mars — 7 years

Rahu — 18 years

Jupiter — 16 years

Saturn — 19 years

Mercury — 17 years

Ketu — 7 years

Venus — 20 years

The Dasha sequence is determined by the Nakshatra (birth star) occupied by the Moon at birth. Different people start life in different Dashas.

💡 Pro Tip

If a Mahadasha planet is well-placed in your birth chart (exalted, own sign, or strong house), that period tends to be prosperous. If it is debilitated or in a dusthana (6th, 8th, 12th house), challenges increase — but remedies help.
