Pitru Paksha Shradh, or Pitr Paksh Shraddh, is the annual rites and rituals offered to ancestors, relatives and dead parents in the month of Ashwin in North India and during Bhadrapad in Gujarat and Maharashtra. Pitru Paksha Shradh 2010 begins on September 24 and ends on October 7. It is popularly believed that the Shradh performed during the Pitr Paksh Shraddh fortnight is highly auspicious as it reaches the dead relatives immediately and therefore their souls attain liberation or rest in peace.
Pitru Paksha Shradh is performed during the Krishna Paksha or waning phase of moon. In some regions, the Mahalaya Shradh Pitru Paksh fortnight begins with Purnima of Bhadrapad month. In majority of the regions it begins on the day after the Poornima.
Mahalaya Shradh is the final day of Shradh and the most important day of Pitru Paksh fortnight. It is also known as Sarvapitri or Sarvapitru Shradh and falls on the Amavasi or no moon day.
