There are total 12 signs. Sade Sati is a relative position of your sign where Moon is posited in your birth chart (Moon Sign or Rashi) and the current position of Saturn (Shani).The currently planetary position is called Transit position or Gochar position in astrological terminology.
When Saturn is transiting through the 12th, 1st, and 2nd house from the natal (birth) moon, this is termed as Sade-sati.
Sate-sati starts when Saturn (Shani) enters the 12th sign from the birth Moon and ends when Saturn leaves 2nd sign from the birth Moon. "Sade-sati" literally means 7 ½ i.e. 'seven and a half'. Saturn stays 2 ½ years on an average in a sign. So, in three signs combined, Saturn stays for 7 ½ and hence it is called Sade-sati.
Similarly, when Saturn passes through the 4th house from the birth moon, it is supposed to give negative results. This position of Saturn is called Ardha Sade-sati (Half-Sade-sati) or Dhaiya, Panoti, or Adhayia.
When Saturn passes through the 8th house from the natal moon, it is called Astham Sani (8th Saturn). This 8th house transit is considered equally negative like the Sade-sati transit.
