Pitru Paksha

Pitru Paksha (Sanskrit: पितृ पक्ष), also spelt as Pitru paksha or Pitri paksha, (literally "fortnight of the ancestors") is a 16–lunar day period in Hindu calendar when Hindus pay homage to their ancestor (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 2nd paksha (forthnight)Hindu lunar month of Bhadrapada (September)and follows the forthnight immediately after the Ganesh festival. It begins on the Padyami (first day of the forthnight) ending with the new moon day known as Sarvapitri amavasya, Pitru Amavasya, Peddala Amavasya, Mahalaya amavasya or simply Mahalaya. Most years, 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, and cultures following the purnimanta calendar or the solar calendar, this period may correspond to the waning fortnight of the luni-solar month Ashvin, instead of Bhadrapada.
