When is the most auspicious time to do Pind Daan in Gaya?

While Pind Daan can be done anytime as per family need (especially after a death), the most spiritually potent time is during:
Pitru Paksha (15 lunar days before Sarvapitri Amavasya, usually in September–October)

• Amaavasya days
• Eclipses (Grahans)
• Gaya Mahatmya days (as prescribed in lunar calendar) Performing Pind Daan during these times ensures maximum spiritual merit (punya) and relief for the souls.
