The Ministry of Tourism outlines the traditional sequence of Chhath Puja as Nahay Khay, Lohanda or Kharna, Sandhya Arghya, and Usha Arghya. Nahay Khay marks the beginning with ritual bathing and home cleaning. Lohanda or Kharna involves an evening offering of kheer and fruits. Sandhya Arghya is dedicated to the setting Sun, while Usha Arghya concludes the festival with offerings to the rising Sun. These rituals are deeply rooted in cultural practices and vary slightly across households.
