Chhath Puja, also called Surya Shashthi, is a four-day festival honouring Surya Dev, the sun god, and Chhathi Maiya. It begins with Nahay Khay and Kharna, and on the third day, Kartik Shukla Shashthi, devotees offer arghya to the setting sun by a river or water body, closing with an offering to the rising sun the next morning.
