In the Chaurchan Puja, the fasting is observed for the whole day. Married women in Mithila clean the courtyard of their houses by smearing it with cow dung.

The following mantras are chanted while offering Arghya which are as follows
सिंहः प्रसेनमवधिस्सिंहो जाम्बवता हतः
सुकुमार मन्दिस्तव ह्येष स्यामन्तकः स्त'[3]
One day Lord Ganesha was roaming on Kailash with his vehicle mouse. Then suddenly Chandra Deva started laughing seeing him, Lord Ganesha did not understand the reason for his laughter. He asked Chandra Deva "Why are you laughing". Responding to this, Chandra Deva said that he is laughing seeing the strange form of Lord Ganesha. At the same time, he also revealed his form. Lord Ganesha got angry at Chandra Deva's tendency to make fun of him. He cursed Chandra Deva that you are very proud of your appearance that you look very beautiful but from today you would become ugly. Anyone who sees you will get a false stigma. He will be called a criminal even though he has not committed any offence. On hearing the curse, Chandra Deva's pride was shattered. He apologized to Lord Ganesha and said, "Lord, free me from this curse". Seeing Chandra Deva repenting, Lord Ganesha forgave him. The curse could not be withdrawn completely so it was said that anyone who would see the moon god on the day of Ganesh Chaturthi. He will be falsely accused. To avoid this, moon is worshiped in Mithila on the evening of Ganesh Chaturthi.[4] Chauth Chand is also mentioned in Brahma Purana. There is a story related to Lord Krishna. According to the story, Lord Krishna was accused of stealing the Syamantaka gem, which was stolen by Prasena. A lion killed Prasena, then Jambavan killed that lion and acquired the gem. After this, Lord Krishna defeated Jambavan in a war and got this gem and became free from the stigma.[5]
According to historians, the festival of Chaurchan Puja became popular in Mithila during 16th century CE. There is a history related to it in regime of the King Hemangad Thakur of Mithila Kingdom. Once King Hemangad Thakur was arrested by Mughal for not paying tax to the Mughal emperor. He was brought to Delhi and sent to jail. In the jail he composed his astronomical text Grahan Mala which is the account of eclipses dates for 1088 years from 1620 AD to 2708 AD. It is said that Mughal emperor Akbar became very impressed with Hemangad Thakur for his work Grahan Mala, so he returned tax free Mithila Kingdom to the King Hemangad Thakur. When Hemangad Thakur came to Mithila with tax free kingdom, Queen Hemalata said "Today the moon of Mithila has become free from stigma, we will see and worship it." After that the people of Mithila started celebrating the festival of Chaurchan Puja with larger enthusiasm. King Hemangad Thakur, with the consultations from Pandits, declared Chaurchan as Lokaparva (Folk festivals) of the Mithila Kingdom. [6]
