Amavasya is the new moon day when the moon is not visible. It is auspicious for Pitru Tarpan (ancestral offerings) and Kali/Shakti worship. Special Amavasyas like Somvati (Monday) and Shani (Saturday) are especially sacred.
Amavasya is the Sanskrit term for the new moon day - the 30th tithi (lunar day) of the Krishna Paksha (waning fortnight) in the Hindu lunisolar calendar. On this day the moon is not visible in the sky, as the lunar and solar longitudes coincide. There are 12 to 13 Amavasya days each year, each falling in a different Hindu month. This calendar lists Amavasya dates from 2024 onwards, calculated from the precise moment the Amavasya tithi begins and ends according to the Surya Siddhanta astronomical system.
Amavasya holds deep religious importance across Hindu traditions. It is the most auspicious day for Pitru Tarpan - the ritual offering of water and sesame seeds (til jal) to deceased ancestors - believed to liberate ancestral souls and bring blessings to the living family. Mahalaya Amavasya in the Ashwin month (September-October) is especially significant: millions across West Bengal, Tamil Nadu, and Andhra Pradesh gather at riverbanks - including the Ganges at Haridwar and the Kaveri at Srirangam - for mass Tarpan. Temples of Lord Shiva observe special abishekam (ritual bathing of the deity) on Amavasya, and some devotees observe strict fasting from sunrise to moonrise.
