what is avani avittam

Avani Avittam, also known as Upakarma, is a Vedic ritual practiced by Hindus of the dvija social classes, which includes the male members of the Brahmin, Kshatriya, and the Vaishya varnas. It is a significant ritual for Brahmins and marks the beginning of the study of Vedas. The ritual involves taking a holy dip, changing the sacred thread, and wearing a new holy thread. Avani Avittam is usually celebrated on the full moon day in the month of Shravana, which falls between August and September. The day is of great significance to the Brahmin community in Tamil Nadu and Kerala. The custom was once practiced by Kshatriyas and Vaishyas, but it is primarily practiced today among the Brahmin community. Upakarma is also known as Avani Avittam in Tamil.
