What is Vimshottari Dasha? — The 120-Year Planetary Cycle
Vimshottari Dasha is the most widely used predictive system in Vedic astrology — a 120-year cycle that assigns ruling periods to each of the nine planets (Navagraha) based on the Moon's Nakshatra at the moment of birth. The word "Vimshottari" means "120" in Sanskrit, referring to the total cycle duration. This system is the backbone of all Vedic timing predictions — it answers the question: "When will specific events happen in my life?"
Each planet rules a Mahadasha (major period) of fixed duration: Sun (6 years), Moon (10), Mars (7), Rahu (18), Jupiter (16), Saturn (19), Mercury (17), Ketu (7), and Venus (20) — totaling 120 years. Within each Mahadasha, nine sub-periods called Antardasha run in the same sequence, and within each Antardasha, nine Pratyantardasha (sub-sub-periods) create finer timing divisions. This three-level hierarchy allows astrologers to predict events with remarkable temporal precision.
The starting point of your Dasha cycle is determined by the Moon's position in one of the 27 Nakshatras at birth. For example, if your Moon is in Bharani Nakshatra (ruled by Venus), your Dasha cycle begins with Venus Mahadasha, with the remaining balance calculated from the exact degree of the Moon within that Nakshatra. This is why accurate birth time is critical — even a few minutes difference can shift the Dasha balance significantly, changing predictions for years.
ShreeKundli's free dasha calculator uses Swiss Ephemeris with Lahiri Ayanamsa to compute your Moon's Nakshatra position to arc-second precision, then calculates the complete Mahadasha, Antardasha, and Pratyantardasha timeline from birth to 120 years. You can also generate your full birth chart (kundali) for a complete Vedic astrology analysis.
Periods
The 9 Mahadasha Periods — Planetary Rulers of Your Life
Moon (Chandra)
Mind, emotions, mother, home, public life. Moon Dasha brings emotional growth, property, travel, and changes in mental landscape — peaceful or turbulent based on Moon's chart position.
Mars (Mangal)
Energy, courage, property, siblings, surgery. Mars Dasha brings action, conflict resolution, land dealings, and physical vitality — or aggression and accidents if Mars is afflicted.
Rahu
Ambition, foreign lands, unconventional paths, obsession. The longest Dasha — Rahu brings sudden rise, foreign connections, technology, and material gains, but also confusion and illusion.
Jupiter (Guru)
Wisdom, wealth, children, dharma, expansion. Jupiter Dasha is generally the most benefic — bringing marriage, children, spiritual growth, higher education, and financial prosperity.
Saturn (Shani)
Karma, discipline, delays, longevity, hard work. Saturn Dasha tests patience — rewards come slowly but are lasting. Career stability for well-placed Saturn; chronic challenges for afflicted. Check your Sade Sati status too.
Mercury (Budh)
Intellect, communication, business, trade, education. Mercury Dasha favors commerce, writing, technology, and learning. Excellent for entrepreneurs, students, and communicators.
Ketu
Spirituality, detachment, past life karma, moksha. Ketu Dasha brings sudden changes, spiritual awakening, and detachment from material pursuits — transformative but unsettling.
Venus (Shukra)
Love, marriage, luxury, arts, vehicles, beauty. The longest single Dasha — Venus brings romance, material comfort, creative success, and life's pleasures. Marriage often happens in Venus Dasha.
Questions
Frequently Asked Questions
Common questions about Vimshottari Dasha and the dasa calculator
What is a Dasha calculator and how does it work?
A Dasha calculator (also called Dasa calculator) computes your Vimshottari Dasha timeline based on your date of birth, time of birth, and place of birth. It first determines your Moon's Nakshatra using precise astronomical calculations, then assigns the ruling planet of that Nakshatra as your starting Mahadasha. The remaining balance is calculated from the Moon's exact degree within the Nakshatra. ShreeKundli's calculator uses Swiss Ephemeris with Lahiri Ayanamsa for arc-second accuracy.
What is the difference between Mahadasha, Antardasha, and Pratyantardasha?
Mahadasha is the major planetary period (6-20 years) — it sets the overall theme of that life phase. Antardasha is the sub-period within each Mahadasha (months to years) — it modifies and refines the Mahadasha's effects. Pratyantardasha is the sub-sub-period (weeks to months) — it creates the finest timing divisions. For example, during Jupiter Mahadasha + Venus Antardasha + Mercury Pratyantardasha, you'd experience Jupiter's expansion filtered through Venus's love/luxury energy with Mercury's communication influence — a great time for a creative business launch or wedding.
Why is birth time important for Dasha calculation?
Birth time is critical because the Dasha starting point depends on the Moon's exact degree within its Nakshatra. The Moon moves approximately 13° per day — so even 15-30 minutes difference in birth time can shift the Moon's Nakshatra position, which changes the balance of the first Mahadasha. This ripple effect alters every subsequent Dasha date. For example, if your Moon balance gives you 3 years of Venus Dasha vs 5 years, your entire life timeline shifts by 2 years. Always use your most accurate birth time from birth certificates or hospital records.
How do I know which Dasha is currently running?
Enter your birth details in the calculator above — the result will highlight your current Mahadasha and Antardasha with exact start and end dates. Your current Dasha determines the dominant planetary influence on your life right now.

Is Vimshottari Dasha the only Dasha system?
No — Vedic astrology has over 40 Dasha systems. However, Vimshottari Dasha is the most universally used and accepted, recommended by Maharishi Parashara in the Brihat Parashara Hora Shastra. Other notable systems include Yogini Dasha (36-year cycle, simpler), Kalachakra Dasha (based on Nakshatra navigation), Chara Dasha (Jaimini system based on signs), and Ashtottari Dasha (108-year cycle using 8 planets). ShreeKundli calculates Vimshottari Dasha as the primary system.
