Govatsa Dwadashi, also known as Vagh Baaras, falls on the twelfth day of Krishna Paksha (new moon) of Bhadra. People observe fast, wishing prosperity and longer life of their sons.
According to Bhavishyapuran - an ancient Hindu treatise, Govatsa Dwadashi is associated with the story of divine cow Nandhini and her calves. Hence this day is also referred to as Nandhini Vrat. The idols of cows and calves made of mud are worshipped on this day.
Offerings such as sprouted moong and gram are made to the deity of Nandhini. It is strictly prohibited to drink cow milk, ghee and curd on this day.
