Traditional Govatsa Dwadashi is a Hindu cultural and religious festival which marks the beginning of Diwali celebrations in some parts of India, especially in the state of Maharashtra, where it is known as Vasu Baras.

In some North Indian states, Govatsa Dwadashi is referred to as Vagh, which implies the repayment of one's financial debts.

It is said that Govatsa Dwadashi was first observed with fasting by King Uttānapāda (the son of Svayambhuva Manu) and his wife Suniti.

[citation needed] Cows and calves are bathed, draped in clothes and flower garlands, and vermilion/turmeric powder is applied on their foreheads.

As cows are symbolic of motherhood and the chief source of livelihood in many villages in India, they are central to Diwali worship.
