Chaturdashi Tithi will start from 6 pm on November 13; this is also called Narak Chaturdashi. On this date, there is a custom to celebrate Chhoti Diwali, a day before Diwali. On this day, Dhanteras, Dhanwantari Jayanti, Yamdeep Daan, and Pradosh fast will all be celebrated.
According to the Hindu Mythology, a day before Diwali night, a lamp is rotated throughout the house by an elderly person of a family and after that, the lamp is kept somewhere outside the house. In this duration, there is also a tradition to worship Yama, the god of death.
Why Chhoti Diwali Is Celebrated a Day Before Diwali?
Long before, there was a king named Rati Dev. He had never committed any sin in his life, but one day the Yamdoots came before him. On seeing the Yamdoot, the king was surprised and said that I have never committed any sin, yet do I have to go to hell? On hearing this, the Yamdoot said that once a Brahmin had gone hungry from your door, this is as same as sin.
The king repented on hearing this. He asked the Yamdoot to give him a year to make atonement. The Yamdoots gave the king one year, the king came to the sages, told them the story, and asked for the solution to get rid of this sin. Then the sage told him to fast on the Chaturdashi of Krishna Paksha in Kartik month and give food to the Brahmins. The king did the same thing as the sage told him to do, and thereafter he was freed from sin. After that, he got a place in Vishnu Lok. From that day, Kartik Chaturdashi’s fasting and lighting the lamp to get rid of sin and hell was observed.
