Pitru Paksha: This 16-lunar-day period (usually Sep-Oct) is the most significant time dedicated to ancestors. Performing Tarpan in Varanasi during Pitru Paksha is highly meritorious.
Mahalaya Amavasya: The last day of Pitru Paksha is considered the most potent day for Tarpan.
Amavasya (New Moon): Every new moon day is auspicious for Tarpan, as the connection with ancestors is believed to be stronger.
Daily: Due to the perennial sanctity of Kashi and Ganga, many devout Hindus perform daily Tarpan after their morning bath at the ghats.
Death Anniversary (Tithi): Performing Tarpan on the specific lunar day corresponding to the ancestor’s death.
