Alright. It is Karva Chauth. So the Wiki page for the same reads,
Karva Chauth (Hindi: करवा चौथ) is a one-day festival celebrated by Hindu women in North India in which married women fast from sunrise to moonrise for the safety and longevity of their husbands. The festival falls on the fourth day after the full moon, in the Hindu lunisolar calendar month of Kartik. Sometimes, unmarried women observe the fast for their fiancés or desired husbands.
Okay then. If this is what the fast does to husbands, it is an awesome life saver, isn’t it? BeingIndian shared a video which is just a exaggerated, but hilarious version of what these fasts should be actually doing to husbands.
