Pitri Visarjan

Pitru Paksha (Sanskrit: पितृ पक्ष), also spelt as Pitru paksha or Pitri paksha, (literally 'fortnight of the ancestors') is a 16–lunar day period when Hindus pay homage to their ancestors (Pitrs), especially through food offerings. The period is also known as Pitru Pakshya, Pitri Pokkho, Sola Shraddha ('sixteen shraddhas'), Kanagat, Jitiya, Mahalaya Paksha and Apara paksha.

Pitru 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, Pitru Amavasya, Peddala Amavasya, Mahalaya amavasya or simply Mahalaya.

The autumnal equinox falls within this period, i.e. the Sun transitions from the northern to the southern hemisphere during this period. In North India and Nepal, this period corresponds to the dark fortnight of the month Ashvin, instead of Bhadrapada.
