Karwa Chauth, also known as Karak Chaturthi, is one of the most celebrated and auspicious Hindu festivals which is observed on the Chaturthi Tithi of Krishna Paksha. This festival falls in the month of Kartik during Krishna Paksha Chaturthi. Widely celebrated across North India, it coincides with Sankashti Chaturthi, which is a fasting day observed for Lord Ganesha.
The term Karwa Chauth has been derived from Karwa or Karak which refers to the earthen pot Argha through which water offering is made to the moon.
Unmarried girls also observe a fast on this day in some regions and pray their future spouses' health and long life. Henna application is an important ritual of Karwa Chauth celebrations. Religious books suh as Dharamasindhu, Nirnayasindhu and Vratraj mention Karwa Chauth as Karaka
