Aadi Amavasya falls on Wednesday, 12 August 2026.

It is the new moon (amavasai) day of the Tamil month of Aadi, one of the most important days of the year to perform tarpanam and shraddha for departed  ancestors. Families offer water and sesame at rivers, seashores and temple tanks to honour their pitrus.
 
Aadi Amavasya is the new moon day that falls in the Tamil month of Aadi, usually between mid-July and mid-August. Aadi Amavasya is not a celebration of a deity but a day set aside for the pitrus, one’s departed ancestors.

Aadi Amavasya is A day for the pitrus
In Tamil belief the amavasai is when the veil between the living and the departed is thinnest. Offering water and sesame on this day is a way of settling the pitru rina, the debt every person owes to those who came before. The rite is meant to bring peace to the ancestors and, in turn, their goodwill to the family.
Time& Calendars. Tamil families gather at riverbanks, seashores and temple tanks to offer tarpanam, a simple libation of water and black sesame, so that the souls of the forefathers are remembered and their blessings pass to the living. It is quiet, reflective and deeply rooted in duty rather than festivity.

The tradition holds that when ancestors are remembered with sincerity, they bless descendants with health, harmony and continuity of the family line. Neglecting them, by contrast, is thought to leave unfinished duty. Aadi Amavasya gives families a fixed occasion each year to keep that bond alive.

Aadi Amavasya honours the pitrus, the departed ancestors, rather than a single presiding deity. Yama, lord of dharma and the departed, and the pitru-devas are invoked as witnesses to the offering.

Central to the day - The Pitrus
The pitrus are one’s own departed parents, grandparents and forebears. The whole observance is directed to them through tarpanam and pinda, asking that they be at peace and continue to watch over the household.

Yama
Yama presides over the realm of the departed and over dharma. He is remembered on ancestral days as the guardian who receives the souls and to whom the merit of the rite is respectfully directed.

Surya and the sacred waters
Offerings are made facing the sun and into flowing or sacred water. Surya as witness and the river or sea as the medium carry the libation, which is why the ritual is performed on banks and shores rather than indoors.

The core rite is tarpanam, a libation of water and sesame offered to the ancestors. It is usually done in the morning after bathing, ideally by a river, the sea or a temple tank.

Feed and give in charity. Many complete the day by feeding brahmins, the poor or animals such as crows, and by giving simple donations, dedicating the merit to the ancestors.

Food and Offerings on Aadi Amavasya
Aadi Amavasya is a day of restraint, not feasting, so the food is deliberately plain and sattvic. Sesame, rice and water are central to the offering itself.

Aadi Amavasya is chiefly a Tamil observance, kept across Tamil Nadu and Few Places are
Rameswaram
The Agni Theertham shore and the temple tanks at Rameswaram draw large crowds who bathe in the sea and perform tarpanam, making it one of the most important places for  ancestral rites on this day.

Kanyakumari
At the southern tip where three seas meet, pilgrims bathe and offer libations to their ancestors, a setting long associated with shraddha and holy immersion.

Rivers and temple tanks
Along the Kaveri, Vaigai and Tamiraparani, and at temple tanks in towns and villages, priests and families gather at the waterside through the morning to complete their offerings.

The Tamil diaspora
Tamil communities in Sri Lanka, Malaysia, Singapore and beyond keep the day too, performing tarpanam at whatever river, sea or tank is at hand, or at their local temple.

The day asks for sincerity and restraint rather than ceremony for its own sake.
