Pitra Paksha 2013 begun on September 19. Pitra Paksha is considered by Hindus to be inauspicious, given the death rite performed during the ceremony, known as Shraddha or tarpan. In southern and western India, it falls in the Hindu lunar month of Bhadrapada (September–October), beginning with the full moon day (Purnima) that occurs immediately after the Ganesh festival and ending with the new moon day known as Sarvapitri amavasya, Mahalaya amavasya or simply Mahalaya.
