The festival begins with Nahay Khay, a day of purification where devotees take holy dips and prepare sattvik meals. The second day, Kharna, involves fasting until sunset, followed by prayers and the preparation of prasad. Sandhya Arghya, the third day, is marked by offerings to the setting sun at riverbanks. The final day, Usha Arghya, includes prayers to the rising sun for health, prosperity, and happiness.
