Ketu Mahadasha7 yrs
Ketu · Parashari Cycle

A stripping-back period. Attachments loosen, interests turn inward, and what survives the seven years is usually what was genuinely yours.

Venus Mahadasha20 yrs
Shukra · Parashari Cycle

The longest of the nine. Relationships, comfort, money and creative work all come forward, and the quality depends heavily on where Venus sits.

Sun Mahadasha6 yrs
Surya · Parashari Cycle

Short and concentrated. Authority, recognition and the relationship with the father or with people who hold rank tend to define it.

Moon Mahadasha10 yrs
Chandra · Parashari Cycle

Emotional weather sets the tone. Home, mother, travel and public reputation move, and the Moon phase at birth matters more here than anywhere else.

Mars Mahadasha7 yrs
Mangal · Parashari Cycle

Energy arrives with an edge. Property, siblings, competition and physical drive intensify, and so does the cost of acting without thinking.

Rahu Mahadasha18 yrs
Rahu · Parashari Cycle

Ambition outruns experience. Foreign connections, unconventional routes and sudden rises are typical, and so are the corrections that follow them.

Jupiter Mahadasha16 yrs
Guru · Parashari Cycle

Expansion with a moral centre. Teaching, children, wealth and belief systems develop, though a weak Jupiter can expand the wrong things just as easily.

Saturn Mahadasha19 yrs
Shani · Parashari Cycle

Slow, structural and unsentimental. Careers get built or rebuilt over nineteen years, and nothing in it rewards shortcuts.

Mercury Mahadasha17 yrs
Budha · Parashari Cycle

Communication, trade, analysis and study take the lead. It is the most adaptable of the nine and the most sensitive to the company Mercury keeps.

What is Vimshottari Dasha in Vedic Astrology?

Vimshottari Dasha (from the Sanskrit "Vimshottari" meaning one hundred and twenty) is the foundational nakshatra-based planetary period system codified by Maharishi Parashara in Brihat Parasara Hora Sastra. Designed specifically for humanity during Kali Yuga, it maps the unfolding of individual karma across an archetypal 120-year celestial lifespan divided among the nine classical Vedic grahas.

The starting point of your Vimshottari Dasha is determined exclusively by the exact astronomical longitude of the Moon (Chandra) at the moment of your birth. The 27 lunar mansions (Nakshatras) are grouped into nine triads, each ruled by a specific graha in an invariant celestial 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).

Unlike generalized horoscope timing, Vimshottari Dasha calculates the exact Dasha Balance (Bhukti Shesha)—the unspent portion of the birth nakshatra lord’s period remaining at your time of birth. This micro-astronomical calculation forms the mathematical foundation for every subsequent Mahadasha, Antardasha, and Pratyantardasha throughout your entire life.

The 120-Year Vimshottari Planetary Allocation Sequence

The Vimshottari cycle follows an immutable order of nine planetary rulers. Ketu initiates the cycle (7 years), followed by Venus (20 years), the Sun (6 years), the Moon (10 years), Mars (7 years), Rahu (18 years), Jupiter (16 years), Saturn (19 years), and Mercury (17 years), totaling exactly 120 solar years.

Whichever planet rules the Nakshatra occupied by your natal Moon becomes your Janma Dasha lord. For example, if born with Moon in Rohini (ruled by Moon), your life begins with the remaining balance of the 10-year Moon Mahadasha, followed directly by Mars (7 years), Rahu (18 years), and so forth.

How to Read Mahadasha vs. Antardasha Interactions

A Mahadasha establishes the overarching life theme, environment, and physical foundation, while the Antardasha lord acts as the dynamic executor of events. If the Mahadasha lord and Antardasha lord share natural or temporal friendship (Mitra sambandha) and occupy favorable mutual house relationships (such as 1st/7th, 3rd/11th, or 4th/10th), the period brings growth and auspicious achievements.

Conversely, if the two lords sit in mutual 6th/8th (Shadashtaka) or 2nd/12th (Dwidwadasa) positions, the period demands caution, health discipline, and conscious remediation, even if both planets are functional benefics.

The Role of Nakshatra Padas in Dasha Results

While the Nakshatra establishes the ruling Mahadasha lord, the specific Pada (quarter of 3°20′) connects directly into the Navamsa (D9) chart. The Navamsa placement of the Dasha lord reveals the subtle soul-level fruits and ultimate manifestation of the period.

Step by Step Guide

How to Calculate Your Vimshottari Dasha Balance

Mathematical steps from birth nakshatra to multi-level period trees

1
Step 1

Identify Moon Nakshatra & Degrees

Calculate the Moon’s exact sidereal position (0° to 30° within its sign) using high-precision Swiss Ephemeris algorithms and Chitrapaksha Lahiri Ayanamsa.

2
Step 2

Determine Nakshatra Arc Traversed

Each Nakshatra spans exactly 13°20′ (800 arcminutes). The Moon’s elapsed arc determines how much of the first planetary period has already elapsed before birth.

3
Step 3

Compute Dasha Balance at Birth

The remaining unelapsed arc fraction is multiplied by the total planetary lifespan allocation to establish the precise years, months, and days remaining at birth.

4
Step 4

Generate Nested Period Tree

Subdivide the 120-year cycle into Antardashas (sub-periods), Pratyantardashas (sub-sub periods), and Sookshma dashas using classical proportionality equations.
