Karwa Chauth is a festival celebrated by the Hindhu and Kashmīri Muslim married women, worshipping for the long lives of their husbands. It falls on the Chathurthi thithi(fourth day) after the full moon in the month of Kārthika(November) in the Hindhu calendar. The day of celebration depends on the duration of the thithis in each location of the World.

Karwa means clay pot and Chauth means fourth day (in this case – night) after the full moon. Married women start their fast at night after the moon rise, within the sight of their husbands and end their fast on the next day, sighting the moon. In the evening, women adorn themselves with fine traditional clothes, jewellery and mehendhi. They break their fast by having their first bite of food and water offered by their husbands on the occasion. During the worship of moon, karwa is filled with specially prepared food and jewellery and is offered to God. Karwas are also exchanged between other women after the prayers. The celebrations also involve telling and listening stories about the origin of the festival.

The style of celebration varies between the communities and their culture. For instance, in Punjab, women start their fast by consuming food called sergi sent or given by her mother-in-law before the dawn. The fast breaking ceremony involves looking at the moon through a sieve , and then looking at her husband's face. They often close their eyes in the process and do not see anyone but their husbands just after seeing the moon.
