First day of Chhath Puja (Nahay Khay)

The First day of Chhath is called Nahay Khay. On this day the Parvaitin (Devotee) take a sacred bath after which the entire house, its surroundings are cleaned. After that the Parvatin cooks Satvik Lauka Bhaat which is served to the deity as Bhog in the afternoon. This is the last meal of the Parvatin during Chhath Puja. After that the 36 hours of vrat (fast) begins.
Second Day of Chhath (Kharna)

The second day of Chhath is Kharna which is also known as Rasiaav-Roti or Lohanda. On this day the devotee keeps a Nirjala vrat meaning that they do not drink even a single drop of water.
At the end of the day (evening) devotees eat gur ke kheer or Raisaav with Roti.
Third day of Chhath (Sanjhka Aragh)

The Third day is spent in making the prasad which is thekua, laddu etc. The devotee put the prasad in the bamboo basket. All the members of the family should take a bath before they went to the riverbank, pond, or other large body of water to make the Arghya. One family member holds the bamboo basket on his head and walks barefoot to the site of Arghya. Beside the devotee and family members even the onlookers will help the devotee to receive the blessing of the worshiper.
At the time of Arghya, jal (water) is offered to Lord Surya and Chhathi Maiya. After Arghya, chhath geet (songs) are sung and Vrat Katha is read. Then, they return to their respective homes to perform the ritual of kosi bharai together with the other family members.
Kosi Bharai

In this ritual, devotees take 5 to 7 sugarcanes and tie them together to form a mandap. Under the mandap, devotees light 12 to 24 Diya lamps. Along with the lamps they put other offerings like thekua and seasonal fruits.
Fourth day of Chhath (Bhorka Argha)

This is the last day of chhath puja in which devotees have to go to the riverbank to offer an arghya to the rising sun. After that, devotees drink water and eat some prasad in order to end their fast. This is called Parana.
History of Chhath Puja
As per legends, Chhath Puja stems from the early Vedic period, where sages would fast for days and perform the puja with mantras from Rigveda.
According to a famous legend, Mata Sita performed the Chhath festival in Munger.On this day Rama and Sita kept fast and Surya Shashthi/Chhath Puja was performed by Sita. Hence, she was blessed with Lava and Kush as their sons. It was only after this event that the Chhath festival started. That is why Chhath Mahaparv is celebrated with great pomp in Munger and Begusarai. Sitacharan temple, situated on a boulder in the middle of the Ganges in Munger, is the main center of public faith regarding Chhath festival.
While in the Mahabharata, It is believed that Karna, the son of Surya and Kunti, was born after Kunti performed Chhath puja.
Draupadi is also said to perform the Puja for Pandavas to win the Kurukshetra War.
Story of Chhath Puja
According to the legend, King Priyavrat, son of First Manu Swayambhu, was very sad because he had no children. Maharishi Kashyap asked him to do a yajna.
According to Maharishis orders, he performed a yajna for a son. After this, Queen Malini gave birth to a son, but unfortunately the baby was born dead.
The king and his family were very sad because of this. Then Mata Shashthi revealed herself in the sky. When the king prayed to her, she spoke, saying: “I am Chhathi Maiya the Sixth form of Devi Parvati. I protect all the children of the world and give the blessings of children to all childless parents.” After this, the Goddess blessed the lifeless child with her hands, so that he came to life.
The king was very thankful for the grace of the Goddess and he worshiped the goddess Shashthi Devi. It is believed that after this puja, this festival became a worldwide celebration.
