Every year Panchami of Shukla Paksha of Bhadrapada month is called Rishi Panchami. Women fast on this day. Sapt Rishis are mentioned in the story of the Matsya avatar of Vishnu. It is believed that if their names are chanted then the effect of the person's sinful deeds goes away. According to Pt. Manish Sharma, Jyotishacharya of Ujjain, during the Matsya avatar of Lord Vishnu, there was a flood in the earth. At the same time King Manu was riding in a big boat with the Dipper. All these were protected by the Matsya avatar of Vishnu. It is said that the name of the Saptarishis should be recited daily.
