Vasudev Dwadashi is celebrated every year in the month of Ashadh and at the beginning of Chatur month. This date always falls a day after Devshayani Ekadashi. Vasudev Dwadashi is dedicated to Lord Krishna. Along with Lord Krishna, Goddess Lakshmi are also worshiped on this day. Chaturmas is a holy period of four months (July to October), beginning on Shayani Ekadashi (Shukla paksha Ekadashi of Ashadh) until Prabodhini Ekadashi (Shukla paksha Ekadashi of Kartik) in Hinduism. It is believed that those who do this special worship in Ashada, Shravan, Bhadrapada, and Ashwini month get salvation.
Fasting on the day of Vasudev Dwadashi has special significance. It is believed that whoever observes fast on this day, all his sins are eradicated and children are attained. By observing this fast, the destroyed state is also recovered. It is said that this is what Narada told Lord Vasudev and Mother Devaki.

It is said that a long time ago there was a country named Chunar. The name of the king of this country was Poundrak. Poundrak's father's name was Vasudev, so Poundrak used to call himself Vasudev. Poundrak was also present in the Swayamvara of the princess of Panchal king Draupadi. Poundrak was an ignorant fool. His foolish and sycophantic friends told Poundrak that Lord Krishna is not an incarnation of Vishnu, but Poundrak is an incarnation of Lord Vishnu. Coming to the words of his foolish friends, King Poundrak started thinking of himself as Krishna by wearing fake chakra, conch sword, and yellow cloth.
One day King Poundrak also sent a message to Lord Krishna that he has taken an avatar to save the people of the earth. Therefore, you leave all these signs or else fight with me only. Lord Krishna did not pay attention to the foolish king for a long time, but when King Poundrak's talk got out of hand, he replied that I will destroy your pride very soon by destroying you completely. After listening to Lord Krishna, King Poundrak started preparing for war with Shri Krishna. He went to Kushinagar to get help from his friend Kashiraj.
Lord Krishna attacked the country of Kashi with full military force. On the attack of Lord Krishna, King Poundrak and Kashiraj came with their own army to fight on the border of the city. During the war, King Poundrak wore a conch, chakra, mace, bow, silky father, etc., and was seated on Garuda. He entered the battlefield in a very dramatic way. Seeing this incarnation of King Poundrak, Lord Krishna got very laughing. After this, Lord Krishna killed Poundrak and returned back to Dwarka. After the war, in the spirit of revenge, Poundrak's son sacrificed the Maran to kill Lord Krishna, but went to Dwarika to kill Lord Krishna; he returned to the flames of Kashi and caused Sudarshan's death. He was the son of the King of Kashi, Sudarshan.
