The festival is dedicated to the sun God, with offerings made to the rising and setting sun. It is observed for four days, from Kartik Shukala chaturthi to Kartik Shukala Saptami. It usually falls between October and November in the Gregorian calendar. The Sun, considered as the god of energy and of the life-force, is worshiped during the Chhath festival to promote well-being, prosperity and progress.
The ritual of Chhat Parba includes taking holy bath, fasting, standing and worshiping sun for a long time and offering Prasad and Argha to 'Rising and setting Sun". RSS
