Pitra Paksha is a 16-day period in the Hindu calendar dedicated to honoring and remembering deceased ancestors. It typically falls in the month of Ashwin, during the lunar phase of Krishna Paksha, which is the waning phase of the moon. Families perform rituals, known as Shraddha, to pay homage to their ancestors, seeking blessings for their souls. During Pitra Paksha, it is believed that the spirits of ancestors visit the earthly realm. Hindus offer food, water, and other items to ensure their ancestors' peace and well-being in the afterlife. This observance emphasizes the importance of family lineage and respect for those who have passed away.
