SS · Sade sati
SS-05: Kantaka shani
Saturn in the 4th, 7th or 10th sign from the birth Moon is called kantaka shani, each stay lasting about two and a half years. The API dates it and says when it is running, next to sade sati and dhaiya. The 4th is both dhaiya and kantaka, so it is listed once with both names.
