Aadi Amavasya is one of the most significant days in Hinduism dedicated to honoring and worshipping ancestors. It is the first Amavasya (New Moon) that falls during the sacred Dakshinayana Punya Kalam. According to Hindu tradition, offering Tarpanam (ritual water oblation) to one’s ancestors on this auspicious day brings happiness, prosperity, and well-being to the entire family.
In 2026, Aadi Amavasya falls on Wednesday, August 12 (Aadi 27).
The Tamil month of Aadi is when the Sun transits through Cancer (Kataka Rasi), the zodiac sign ruled by the Moon. Amavasya occurs when the Sun and Moon come together in conjunction.
Since the Sun is regarded as the significator of the father (Pitru Karaka) and the Moon represents the mother (Matru Karaka), worshipping ancestors on this day holds immense spiritual importance. It is believed that on Aadi Amavasya, departed ancestors visit the earthly realm to bless their descendants with health, prosperity, and happiness.

Neglecting one’s duties toward ancestors is believed to result in Pitru Dosha (ancestral affliction). This dosha may create obstacles, delays, and hardships within the family.
If you believe you are experiencing the effects of Pitru Dosha, it is beneficial to understand the complete remedies for Pitru Dosha and perform the prescribed rituals with devotion.
Apart from Aadi Amavasya, Thai Amavasya and Mahalaya Amavasya are also considered highly significant for offering Tarpanam to ancestors.
However, observing a fast and performing prayers on every monthly Amavasya is regarded as spiritually beneficial. You can also check the complete list of Amavasya dates and timings for the current year.

Therefore, on this sacred occasion of Aadi Amavasya, let us observe the fast, perform charitable acts, offer Tarpanam with devotion, and seek the divine blessings of our forefathers for peace, prosperity, and harmony in our lives.
