Shani Chalisa

Shani is one of the Navagraha of Jyotiṣa. Shani is embodied in the planet Saturn and is the Lord of Saturday. Shani is also known as Sanaiscara. The word shani also denotes the seventh day or Saturday in most Indian languages. The word shani comes from Sanaye Kramati Sah, the one who moves slowly, because Saturn takes about 30 years to revolve around the Sun.
