Karwa Chauth is the celebration of togetherness that pays tribute to marital bonds. On this day, married women fast from sunrise to moonrise for the wellness and longevity of their husbands. The day of karwa chauth usually falls on the fourth day of Purnima in the month of Karthika according to the Hindu calendar. There are also some areas in India where unmarried women take fasting for the well-being of future husbands.
