Amavasya is held the most auspicious day to give in the name of your ancestors. On this day you can give food and grain in the name of your pitra, once, on the coming Amavasya.
The daan is made with a sankalp in your name, gotra and place. The temple's pandit ji takes the sankalp and makes the daan at the right muhurat.
You can choose any amount from ₹101 to ₹10,001. The temple gives food and items worth the amount you give.
The amount is charged 5 days before the daan date, so the temple can buy the items in time.
After the daan, the temple sends a photo and the details of the sankalp.
