ஆடி அமாவாசை
When is Aadi Amavasya in 2026?
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. Unlike most entries in the festival calendar, it is not a celebration of a deity but a day set aside for the pitrus, one’s departed ancestors. 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.
Aadi Amavasya 2026-2028: Dates & Calendar
The next Aadi Amavasya is on 12 August 2026. Because it tracks the moon, the date shifts each year within the Tamil month of Aadi.
| Year | Date | Day | Notes |
|---|---|---|---|
| 2026 | 12 August | Wednesday | Next occurrence |
| 2027 | 2 August | Monday | New moon in Aadi |
| 2028 | 21 July | Friday | Falls early in Aadi this year |
The new-moon tithi typically spans parts of two days; observers perform tarpanam during the daytime hours when the amavasai tithi prevails, so families check a local panchang for the exact window.
Why Aadi Amavasya Is Observed
Aadi Amavasya is observed because the new moon is held to be the most receptive time to reach and honour departed ancestors, and Aadi is the month traditionally devoted to remembrance and inner discipline.
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.
Why the Aadi month
Aadi is regarded as an austere, introspective month when weddings and new ventures are usually paused. That inward mood suits acts of remembrance, so the new moon of Aadi carries special weight for shraddha. It is one of a small handful of amavasais in the year considered especially potent for ancestral offerings.
Blessings that flow both ways
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.
Whom the Day Honours
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.
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.
How Tarpanam Is Performed, Step by Step
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.
- Bathe and prepare. Observers rise early and take a bath, preferably in a river, the sea or a tank at a holy site. Clean, simple clothing is worn and the body and mind are kept in a calm, austere state.
- Make the sankalpam. Facing the appropriate direction, the person makes a sankalpam, a brief statement of intent naming the day and the ancestors to be honoured, often guided by a priest or family elder.
- Offer water and sesame. Cupped water mixed with black sesame (til) and a little rice is poured out through the fingers while remembering the departed by name. This tarpanam is the heart of the observance and may be repeated for each ancestor.
- Offer pinda where practised. Some families prepare pinda, small balls of cooked rice, and offer them along with darbha grass as a fuller shraddha, though many households keep to the simpler tarpanam alone.
- Perform the rite at water. Wherever possible the offering is made standing in or beside flowing water, at Rameswaram’s Agni Theertham, at Kanyakumari, at riverbanks or at a local temple tank, so the libation is carried away.
- 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.
- Keep a sattvic fast. The day is often observed with light, sattvic food or a partial fast, avoiding feasting so that attention stays on remembrance rather than celebration.
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.
Black sesame and water
Til (black sesame) mixed with water is the essential material of tarpanam, poured out for the ancestors. It is offered rather than eaten, and is considered the most auspicious substance for ancestral rites.
Rice balls (pinda)
Small balls of cooked rice, the pinda, are prepared by families who perform a fuller shraddha. They are offered with darbha grass and set aside for the ancestors, sometimes left for crows to take.
Simple sattvic meal
After the rite the family usually eats a modest vegetarian meal, often without onion or garlic. There is no festive sweet or elaborate spread, keeping the mood sober and dedicated to remembrance.
Where Aadi Amavasya Is Observed
Aadi Amavasya is chiefly a Tamil observance, kept across Tamil Nadu and by the Tamil diaspora, with the largest gatherings at coastal and riverside pilgrimage sites.
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.

Which god is worshipped on Aadi Amavasya?
Aadi Amavasya is not centred on a single deity; it honours the pitrus, the departed ancestors. Yama, who presides over the departed and over dharma, and the pitru-devas are invoked, and offerings are made facing the sun and into sacred water. It is an ancestral rite rather than a temple festival.
What is tarpanam and how is it done?
Tarpanam is a libation offered to ancestors, made of water mixed with black sesame and a little rice. After bathing, the observer makes a sankalpam and pours the water through the fingers while remembering each ancestor by name, ideally at a river, the sea or a temple tank.

Should you fast on Aadi Amavasya?
Many people keep a light fast or eat only simple sattvic food on Aadi Amavasya, avoiding onion, garlic, non-vegetarian dishes and intoxicants. The restraint helps keep the focus on remembering ancestors rather than on celebration. A full fast is a personal choice and not compulsory.
Is Aadi Amavasya the same as Aadi Perukku?

Both belong to the Tamil month of Aadi but serve very different purposes.
May the offering of a little water and sesame carry your remembrance to those who came before, and may their blessings stay with your family. ஆடி அமாவாசை நல்வாழ்த்துக்கள்.
