Dasha system is the foundation of Vedic Astrology, commonly known as Jyotisha Shastra. "Dasha" means the major period of a planet. Dasha method is an ideal method of progression through Navagrahas or Rashis. Dasha system is an exclusive technique to assess a particular planet's influence on each of the moon signs or nakshatras.

It is a time period ruled by a certain planet that unfolds during one's lifetime. They denote good and bad effects on the planet. There are over 42 distinct types of Dasha systems formulated by Maharishi Parashara in his great work called Brhat Parashari Hora Shastra (BPHS).

Among them, Vimshottari occupies a very prominent place as most Jyotishis of the current time using this. However, it is said that there are many more Dasa systems, 42 of them which Maharishi Parashara narrated in his immortal work Brhat Parashari Hora Shastra (BPHS). Here is an attempt to bring all these Dasa systems in one place for the knowledge of avid learners of this discipline.

Although barring one or two dasa systems, not many are accepted in general usage nowadays. It is important to know that their utility in the current age has not diminished. They are as useful as before, but one needs to understand their right usage.

Significance of Dasha

Dashas provide a clear overview of predicting the effects of the planets throughout a person's life. Dasha can also indicate how every planet coordinates with other planets that come into contact. Each dasha is controlled by a specific planet, and other planets influence the quality and nature of that dasha.

The relative benevolence of each period is calculated by the position of that specific planet in the individual's natal chart. Understanding Dasha systems unfold every dimension of life, life events, and exact period of occurrence

Dashas, in short, are timing methods to predict the accuracy of planets and planetary effects on a native. There are about 42 kinds of dasha frameworks.

Dasa at birth: similar to Vimshottari i.e., from last segment of Moon in the Janma Nakshatra. 

Tara Dasa:
