Karva Chauth is a Hindu festival observed by women in Northern and Western India, typically on the fourth day of the Krishna Paksha or dark fortnight in the month of Kartik. During this festival, married women observe a fast and offer prayers for the prosperity and well-being of their husbands. Unmarried women also partake in the fast with the hope of finding their desired life partner. The celebration is based on a lunisolar variation of the Hindu calendar.
