According to the Amanta Hindu calendar, Krishna Paksha Chaturthi of Bhadrapada month (Purnimanta Ashwina month) is celebrated as day of Vighnaraja Sankashti. On this occasion, Lord Vighnaraja is worshipped and fast is observed. Lord Vighnaraja is the seventh form in Ashta Vinayaka forms of Lord Ganesha. Worshipping this form of Ganesha removes all kinds of obstacles and brings success in work.
According to Hindu legends, once upon a time Lord Ganesha appeared to kill Vighnasura, but after seeing the power and bravery of Lord Ganesha, Vighnasura took refuge in Him. Lord Ganesha was pleased when Vighnasura apologized and praised Him. Lord Ganesha told Him to ask for a boon. Vighnasura requested to add his name to the name of Lord Ganesha as a boon. Therefore, to fulfill the boon, Lord Ganesha became known as Vighnaraja.
According to the description related to the emergence of Lord Vighnaraja in Mudgal Purana, Lord Ganesha appeared as Lord Vighnaraja to kill the demon named Mamtasura. In Dwapara Yuga, Lord Krishna had observed this great fast on the advice of Lomasha Rishi to get His kidnapped grandson Aniruddha. As a result of the fast, He killed Banasura and freed Aniruddha.
