The dasa at birth of a person depends upon the position of the Moon at the time of his birth.
When a person is passing through the dasa of a particular planet he will face the maximum or minimum effects of that planet's influence depending whether the planet is exalted or low, benefic or malefic, and aspected by other friendly or enemical planets.
Each dasa is further divided into 9 parts, each of which is known as a bukti. Each bukti, in each dasa, has again different durations.
In the sub menu for Dasabukti, under Horoscope menu, the beginning and finishing dates of each dasa and bukti are computed for a person and displayed. |
