To understand more about Vimshottari Dasha, one first needs to understand what it is, 'Dasha'. Any person with a primary interest in Vedic astrology must have come across this term. So what does it stand for?

'Dasha' is a Sanskrit term commonly used in Vedic astrology literature. It is representative of the duration for which a particular planet has the most potent effect on a person's life. In other words, it is the period of progression of planets in such a way that it has the most dominant factor controlling the events in a said person's life. The factors that may affect these events include:

  • The Dasha planet's position.
  • Association with the rest of the planets and other cosmic influences.
  • The planets with which it is forming conjunction.

The positive or negative results of these Dashas also depend on the Rashi, Bhava, Yogas, etc., for the given planet at any specific time.

As per Rishi Parashar, who is also credited as the' Father of Vedic astrology', there are 42 Dasha systems. But at present, few of them are well known, and even fewer are in use. Some of the better-known Dashas include Vimoshattari, Ashtotri, and Yogini dasha. Currently, the most prevalent Mahadasha system in use is the Vimoshattari Dasha.

Vimoshattari Dasha spans upto a period of 120 Solar sidereal years. It corresponded to the belief that earlier, the average human lifespan was about the same time. This Mahadasha period was divided into unequal periods based on the years for which a particular planet would be responsible for projecting its influence on all aspects of a person's life. Vimoshattari Dasha is based on the Nakshatra system, which depends on the progression of the Moon through the astrological sky.


The Vimoshattari Dasha period can be divided into 9 Mahadasha periods, each of which is ruled by a particular planet as per Vedic astrology. These are the seven traditional planets of astronomy and the North and South intersecting nodes of the Moon's orbit. Each planet's Mahadasha, that is, the period it lasts for are given below:

  • Sun (Surya) - 6 years
  • Moon (Chandra) - 10 years
  • Mars (Mangal) - 7 years
  • Jupiter (Guru) - 16 years
  • Saturn (Shani) - 19 years
  • Mercury (Budha) - 17 years
  • Venus (Shukra) - 20 years
  • Rahu - 18 years
  • Ketu - 7 years

Vimshottari dasha is a cyclic occurrence; hence, there is a fixed sequence of planets, which will have the dominant effect after the last planet. This order is in the following pattern: Ketu-Venus-Sun-Moon-Mars-Rahu-Jupiter-Saturn-Mercury.

These Mahadashas are further subdivided into nine smaller segments, each of which is ruled by a different planet. It is done to more accurately predict the frame of occurrence of an event. These units are known as Antardashas.

It is now more of a focused aspect as the average longevity of a person's life has decreased over time. Hence, they don't live long enough to experience all the Mahadashas.

Now, which will be the first planet to influence a person depends a lot on the Nakshatra system and, hence, on a person's birth time. Also, the intensity and limit of effect of a planet during its dasha period are ever-changing. It is so because the planets are continuously shifting from their position and in respect to each other.

The nine sections of the mahadasha are assigned to each of the nine planets. It is known as the "Bhukti," "Antardasha," or "sub period." Therefore, nine bhuktis are allotted for each Dashaa. The planet whose mahadasha is currently in motion will always have the first Antar Dasa period.

The planets in the following Antar Dashas will be in the same order as above. Pratyantar Dasha, Sookshma Dasha, and Prana Dasha are the subgroups that are further divided into it similarly. The length of each cycle will be measured in days or even hours as one delves more into the Sookshma and Prana dashas.

What are the cycles of Mahadasha?

This Dasha is the most famous in Astrology, and a specific time period is designated for all the nine planets under this method. For Mahadashas of all the nine planets, there is a full circle of 120 years.

According to this system, the average age of a human is 120 years, so they may have lived through each Mahadasha in one lifetime.

In the past years, for various reasons, a person's average lifespan has gone down by 50% compared to ancient times. Therefore, because of this, a person cannot experience the effects of Mahadashas on all planets. Keeping this in mind, there are other methods of calculating dashas. According to Vedic Astrology, these methods are known as Antardasha, Pratyantar Dasha, and many more. These methods are usually known as "Sub Dasha" and "Sub Sub Dasha". The division of Antardasha into nine parts gives us the Pratyantar Dasha.

The order of sub-division of the Dasha system is:

Mahadasha>Antardasha>Pratyantar Dasha>Sookshma Dasha>Praanadasha>Dehadasha

All these periods are sub-parts of Mahadasha, and an individual can experience all planetary Antardashas in their lifetime.

How is Mahadasha Calculated?

According to the promising method introduced in Vedic Astrology to determine the period of Mahadasha, three Nakshatras are allocated to each of the nine planets. Thus, the number of Nakshatras is now twenty-seven. The Mahadasha period of a planet is based on the placement of the Moon in certain Nakshatras. Therefore, the Nakshatra Lord is responsible for deciding the period of certain planets at the time of birth.

Another factor that weighs in the duration of Dasha is the degree of the Moon in a particular Nakshatra. If the Moon enters into a Nakshatra at the time of an individual's birth, then they will get a full Mahadasha of the ruling planet of that Nakshatra. Likewise, suppose the Moon passes over a Nakshatra, but a few degrees remain in the constellation. In that case, there will be a brief period of Mahadasha if the ruling planet of the certain Nakshatra.

What are the Fixed Years of the Mahadasha Cycle of Planets?

  • Ketu - 7 Years
  • Venus - 20 Years
  • Sun - 6 Year
  • Moon - 10 Years
  • Mars - 7 Years
  • Rahu - 18 Years
  • Jupiter - 16 Years
  • Saturn - 19 Years
  • Mercury - 17 Years

The above-given order is the order followed for Mahadasha.

How do I determine the results of Vimshottari Dasha?

The rule that is described to know the results of Mahadasha in planets is through the Lagna sign. The Lagna or Ascendant can determine any auspicious or inauspicious effect of a particular planet through the Lagna or Ascendant sign. However, results can vary from Lagna to Lagna as the good planets under one can be inauspicious for some other Lagna. For example, Saturn is an auspicious planet and a Yog Karak planet for Taurus Lagna, but Mars is a beneficial planet for a Cancer Lagna.

This example shows how different planets influence different Lagnas.

The strength of Lagna and the power of benefic planets need to be checked because it will decide on certain planets' whole and partial results.


Each planet has a specific aspect of life that affects more than the other spheres. So, the effect of each Graha is listed below:

  • Sun's Mahadasha: The positive aspect of the Sun is that if the Sun is in a favourable position or if it is situated in the Trine, Kendra, or 11th House, a person may become wealthy in all ways during this period. A person can have popularity, a name, and everything necessary during this time. The negative aspect is that one may go through this period with mental, emotional, or even physical issues due to the Sun's unfavourable placement.
  • Moon's Mahadasha: The Moon would be advantageous if a Trine or Kendra formed by the Moon or the Moon itself were in the 11th House since it is one of the Lagnas. The Moon will be in a good position in the Vimshottari Dasha.

Both money and good mental health are abundant as a result. It counts for the favourable effects of Moon's Mahadasha. But on the flip side, mental illnesses, depression, and loss of income and prestige are likely to occur when the Moon is unfavourable to your position.

  • Mercury's Mahadasha: When Mercury is in one's favour, one can anticipate experiencing great happiness and peace of mind. However, Mercury's negative position can lead to various problems, including stress, financial loss, theft, and mental health issues. Speaking with an astrologer is usually preferable to counteract its harmful influence.
  • Venus's Mahadasha: When Venus is in the 11th House, or the Kendra or trine of this House, a person may pursue a career as an artist, musician, or poet. Alcohol and drug addiction can be caused by Venus being a bad sign in a person's birth chart. They may experience issues in both their personal and professional lives. In addition, they can lose contact with their loved ones.
  • Mars's Mahadasha: Mars strengthens a person during their trying time, so if it's in a good position, it will probably defeat its competitors. Mars's good influence will amplify one's natural bravery and ferocity. But in hindsight, A malefic Mars can be dangerous too.

It is often associated with anger issues and sometimes even with certain vices. A bad influence of Mars can cause problems in a person's romantic and marital life too.

  • Jupiter's Mahadasha: One can excel as a philosopher, counsellor, teacher, or yogi, while Jupiter's phase is prominent. However, a bad Jupiter can cause a lot of anxiety. One can also encounter a great deal of bad luck and disaster.
  • Saturn's Mahadasha: The person is likely to benefit much if Saturn is in the 11th House or the trine to the 11th House. The seniors will be aware of and applaud their hard effort. However, if Mars, Rahu, and Ketu are also placed unfavourably, it would also have a negative impact. Numerous people may lose their money, which may even endanger their lives.

A bad Saturn will impact one’s daily activities and employment. If one can adjust their regular work schedule, they might be able to mitigate its harmful effects.

  • Rahu's Mahadasha: Rahu is believed to have a good position in someone's Kundli if they want to earn recognition, riches, or other unanticipated benefits. Beneficial Rahu can compel you to make pilgrimages as well. A bad Rahu can bring about many things, including disease, pain, death, banishment, and jail.
  • Ketu's Mahadasha: Moksha, or freedom, is represented by Ketu. If one arranges things properly, then they may be able to gain on all fronts. They bring joy and happiness to their life and are loved by important people. However, if their Kundli has a weak Ketu, they may experience backbiting, nasty malice, and much more.


The direct relation between these two is that the Nakshatras decide which planet would first affect a person and, subsequently, the order of planets for the Vimshottari Dasha for one individual. It is also the Moon's position in a particular Nakshatra, which determines the strength of a planet's Dasha on a person born under it.

There are three nakshatras given to each planet. The Nakshatra in which the Moon is placed at the time of birth will become the birth star or Janma Nakshatra. The native's first Dasha will begin with the lord of that star.

After that, the other planets' Dasha sequence begins. So this is the first stage in figuring out the native's Dasha beginnings.

Life events are governed by a particular planet when that planet's dasha is active. The Bhogansh (period) in which Nakshatra calculates the Dasha period. A person will only experience the remaining Dasha period of the planet if some time had passed during that Dasha before their birth.

The Nakshatras allotted to each planet are:

  • Sun (Surya) - Krittika, Uttara Phalguni and Uttara Ashadha
  • Moon (Chandra) - Rohini, Hasta and Shravana
  • Mars (Mangal) - Mrigashirsha, Chitra and Dhanishta
  • Jupiter (Guru) - Punarvasu, Vishakha and Purva Bhadrapada
  • Saturn (Shani) - Pushya, Anuradha and Uttara Bhadrapada
  • Mercury (Budha) - Ashlesha, Jyeshta and Revati
  • Venus (Shukra) - Bharani, Purva Phalguni and Purv Ashadha
  • Rahu - Ardra, Swati and Satabhisha
  • Ketu - Ashwini, Magha and Mula


The Moon's positions in various constellations are used to calculate the Vimshottari Dasha system's essential parameters. In a 360° zodiac, there are 27 nakshatras or constellations, and all the planets will move along these stars. The planets will therefore be positioned in one of the 27 nakshatras at any given time.

Each Nakshatra's area of influence is 13°20' (or 13*60+20 = 800'). Each Pada, also known as a quarter, is the part in a Nakshatra that is divided into four equal portions, each of which has an arc of 3°20'. To compute the Vimshottari Dasha system, one must be aware of the Moon's location.


Vimoshattari dasha takes a person's date and time of birth and then checks back to what part of the Mahadasha cycle they were born at. After that, the calculator predicts the passage of plants whose dasha the person will experience in a systematic order. This calculator also has consideration of the Antardashas and other planetary effects and hence can tell which period will be auspicious and the more challenging periods in a person's life.

It is a relative thing to decide. Because, apart from the planet whose dasha period is active, other planets' position and association also play a significant role in how the dominant planet will affect a person. So, for any Mahadasha to be good, it must have ideal conditions as supported by other planets.
There are two justifications given for it. First, when it was written in the Vedic times, the average life span was considered 120 years. Hence, the life span corresponded to each cycle of Mahadasha. And a person enjoys the effects of all the planets throughout their life. Secondly, as backed by mathematical calculations, the Dasha period of each planet, when added up, sums up to 120 years.
Under this Dasha, which is calculated for 120 years, the duration of this cycle is divided into unequal periods. Each planet is allotted a fixed period in which they are known to have the most significant influence on a person's life. So, in short, Vimshottari Dasha traces the effects of various planets on a person's life.
The Saturn Vimshottari Dasha lasts for 19 years. Therefore, understanding the Saturn vimshottari dasha is crucial because this is when a person comes to terms with their humane limitations and the idea of mortality.
In the present-day context, the Vimshottari Dasha system is the most compatible system used in Vedic astrology. Because the period is easy to divide and subdivide, the basis of division is well-defined and easy to understand, and consideration for other influences is easy to consider under this system.
A planet which has the most strength in a Kundali will be the most effective and influential during its Mahadasha period. If the Mahadasha planet is powerful, it will impart strength to the Antardasha planet to give results accordingly. Vice versa, if the Antardasha planet is strong, it will influence the Mahadasha planet to give outcomes accordingly. The Vimshottari Dasha or Mahadasha period influences human life depending upon the mighty lordships of certain Mahadasha planets.
When there is about to be some substantial change in a Mahadasha period, significant changes are observed in the behaviour of the native. Since the Dasha and Mahadasha are related to the Moon, the first noticeable change will be observed in the individual's behaviour.
According to Vedic Astrology, the Ketu Mahadasha period is an unlucky Dasha. It is believed that Ketu is inefficient towards the Sun; thus, during this period, a person will face many challenges and obstacles.
