Shani is embodied in the planet Saturn. He presides over the Saturday. The word shani also denotes the seventh day or Saturday in most Indian languages. It is to note that Shani is elder brother of Yama, the god of death according to the Hindu mythology.

Shani, along with the goddess Jyestha, are associated with the crow in the Hindu mythology. According to Hindu mythology crows represent harmful and inauspicious characteristics, both of which Shani possesses. The Hindu traditions often include the worship of Shani in order to dismiss dangerous ghosts and other supernatural beings.
