What are the main types of Shradh Karma?

Shradh is classified into several types based on timing and purpose. Nitya Shradh is performed daily through simple Tarpan or food offerings. Naimittika Shradh covers occasion-specific rites like the annual death anniversary (Tithi) Shradh and Mahalaya Shradh during Pitru Paksha. Kamya Shradh is performed to fulfill specific desires such as progeny or prosperity. Parvana Shradh is the collective ancestral rite done on Amavasya and during Pitru Paksha, involving Pinda Daan for three generations.
