In Hinduism, Pitru Paksha is the ritual performed by relatives for the departed souls of dead ancestors, parents and relatives. Tarpan and Shradh are performed on all Amavasi or no moon days. But the most important period to perform Shradh is the Pitru Paksh Period during the Krishna Paksha fortnight in Ashwin month (September October). In some regions this period is the Bhadrapad Krishna Paksha.
