Vimshottari Dasha - Planetary Period Calculator

Vimshottari Dasha is the most widely used planetary period system in Vedic (Jyotish) astrology. It divides a human lifespan of 120 years into periods ruled by 9 planets (Navagrahas) in a fixed sequence: Ketu (7 years), Venus (20 years), Sun (6 years), Moon (10 years), Mars (7 years), Rahu (18 years), Jupiter (16 years), Saturn (19 years), and Mercury (17 years). The starting point of the cycle is determined by the Janma Nakshatra - the birth star occupied by the Moon at the moment of birth.

Mahadasha, Antardasha, and Pratyantar

Each major period (Mahadasha) is divided into nine sub-periods (Antardasha or Bhukti), which are further divided into Pratyantar Dasha and beyond. A skilled Jyotishi uses these nested periods to time life events: career changes, marriages, financial gains, health challenges, and spiritual breakthroughs. The system has been described in classical texts such as the Brihat Parashara Hora Shastra, composed by Maharishi Parashara over 1,500 years ago and still the foundational reference for Vedic astrologers across India and among the global diaspora.

Frequently Asked Questions

Vimshottari Dasha is the most widely used planetary timing system in Vedic astrology. It is a 120-year cycle divided into 9 planetary periods. The sequence is: Ketu (7), Venus (20), Sun (6), Moon (10), Mars (7), Rahu (18), Jupiter (16), Saturn (19), Mercury (17). The starting point is determined by the Moon's nakshatra at birth.

Mahadasha is the major 9-planet period. Within each Mahadasha, all 9 planets get sub-periods (Antardasha) in proportion to their Mahadasha years. Within Antardasha, there are Pratyantar Dashas. The pattern of lords always follows the same Vimshottari sequence starting from the Mahadasha lord.

Find your current Mahadasha and Antardasha. Study the nature of both planets and their positions in your birth chart. The combination of the two lords colors the themes of the period. Major life events (marriage, career changes, health issues) often coincide with dasha-antardasha combinations involving the relevant house lords.

Yes. After Mercury completes its 17-year period, the cycle repeats from Ketu. Most people experience at most 2-3 complete rounds of some planets within a normal lifespan. The full 120-year cycle is rarely completed by any individual.
