In India from time immemorial, the welfare of husbands has always been of prime importance for all married women. Nine days before Diwali, some time in October or November, on the Kartik ki Chauth, Karwa Chauth is undertaken. A fast is undertaken by married Hindu women who offer prayers seeking the welfare, prosperity, well being and longevity of their husbands. It is probably the most important fast undertaken by women of North India.
