Human life is considered to be 120 years as per Vedic Astrology and is divided into several periods or Dashas. These Dashas are commonly known as Vimshottari Dashas and this system is called the Vimshottari Dasha system. Each Dasha is governed by a particular planet. Dashas are further sub-divided into Antar-Dashas (sub-periods) and Pratyantar-Dashas (sub-sub periods). The breakup up of the main dashas ( in the order in which they govern your life) is given below. Please note that the exact Dasha that was running when you were born depends on your
personal horoscope based on your date, time and place of birth. You could for example be born when Rahu Dasha was running which will then be followed by Jupiter, Saturn etc in that order. Each Maha Dasha is further sub-divided into 9 Antar Dashas (1 for each planet ) and each Antar Dasha is further sub-divided into 9 Pratyantar Dashas.
