About Aadi Amavasai

Aadi Amavasai is the new moon day of the Tamil month of Aadi, in July or August. It is one of the most important days of the year to remember and honour one's ancestors.

Families offer tharpanam, prayers with sesame seeds and water, for their departed forefathers, often at the sea or a river. Rameswaram, Kanyakumari, Thiruvaiyaru and other sacred shores see huge gatherings at dawn.

Many people fast, feed the poor and crows, and visit temples. It is a quiet, respectful day of gratitude rather than celebration.

Where it began

Amavasai is the new moon. Hindu tradition holds that the new moon is a good time to remember those who came before. Of all the new moons, those of Aadi and Thai are held most special.

The rite is called tharpanam: water with black sesame seeds is offered to the ancestors with their names. It is a way of saying thank you and asking for their blessing on the family.

How it grew over time

  1. Ancient times

    Remembering ancestors with water and food offerings is an old custom in Hindu homes.

  2. Medieval period

  3. Today

    Large crowds gather at Rameswaram, Kanyakumari and river ghats.
