Chhath puja 2016: 4-day long Chhath Puja begins with Nahai-Khai on Friday

On the third day, people congregated at river banks, rivulets and other water bodies while standing inside the knee deep water and pay arghya to the setting Sun. They return to the same ritual spots on the next day and pray to the Sun god, marking the end of the 4-day festival.
