About Shraddh Tithi
Shraddh (Śrāddha) is the rite Hindus perform to honour and nourish departed ancestors (Pitru). It is offered each year on the tithi — the lunar day — on which the person passed away, rather than on the English calendar date, because the Hindu calendar follows the Moon.

Pitru Paksha
Pitru Paksha is the fortnight (Bhadrapada Purnima to Ashwin Amavasya) set aside for ancestor rites. Each day matches a tithi, and the family performs Shraddh on the day matching their ancestor's death tithi. If the tithi is not known, Sarvapitri (Mahalaya) Amavasya, the final day, is observed for all ancestors. Dates are calculated from the sidereal Sun and Moon (Lahiri ayanamsa) and shown for India (IST).
