Karva Chauth is supposed to be originated as a social and seasonal festival, but somewhere the festival deviated from its original form. The word Karwa Chauth, is composed of Karwa – meaning a clay pot - and Chauth (from char meaning four) corresponding to the fourth day after the Full Moon in Kartik month (of Hindu calendar) following the Autumnal Equinox.
This time of the year is just after the harvest of Kharif (monsoon) crops and people are usually in a festive mood. They like to remember and meet their relatives and friends, and exchange gifts with them. Diwali is a similar seasonal festival – in addition to having religious significance – that is nine days after Karva Chauth.
