Actual period of Sade sati of Saturn is approximately seven and half years and it repeated after each thirty years of one’s life.Among the Seven and half years first two and half years period when Saturn presents one house before the position of Moon is considered as the 1st phase of Sade Sati of the Saturn. Generally it is said that during this phase younger members of the family of a Native are effected.The 2nd phase of Sade Sati of Saturn starts when the transit of Saturn is directly with the Moon.Generally it is said that during this phase the Native himself is mostly effected.And the third phase of Sade Sati starts when the Saturn presents one house after where the moon located and in this phase the elder members of the Native are effected.But as per my practical experience the entire phase of Sade Sari that means of seven and half years , the Native hardly suffered from many discomforts regarding education, career, marriage , married life, children education, health, wealth, success in life , achievements etc according to age of the Native.It is also true that certain planetary conditions and position of Saturn may reduces the detrimental effects of Sade Sati of Saturn.
