Chhath is an ancient Hindu Vedic festival which is historically celebrated in Bihar-Jharkhand, Chhattisgarh and India's eastern Uttar Pradesh and Nepal in the most elaborate form.

• This festival is celebrated not only in India but also in foreign countries. This festival has now become prominent in the India capital, Delhi. The Chhath Puja is dedicated to the Sun and his wife Usha in order to thank them for bestowing the bounties of life on earth and to request the granting of certain wishes.
• It is called Chhath due to Sun Shastri's fasting. This festival is celebrated twice a year. For the first time in Chaitra and the second time in Kartik. The festival celebrated on the Chaitra Shukla Paksha Sashti is called Chaitra Chhath and the festival celebrated on the Kartik Shukla Paksha Sashti is called Kartik Chhath.
