According to the Hindu Panchang, the Krishna Paksha Dwadashi that falls approximately fifteen days after the Margashirsha Shukla Matsya Dwadashi is called Krishna Matsya Dwadashi. The name Matsya Dwadashi is derived from the Matsya Avatara of Lord Vishnu. As described in the sacred Hindu scriptures, the Matsya Avatara is considered the first among the ten principal incarnations of Lord Vishnu, known as Dashavatara. Worshipping Lord Vishnu or His Matsya form on the day of Dwadashi grants the fruits equivalent to performing numerous Yajnas.
The Bhavishya Purana also mentions another fast known as Samprapti Dwadashi, which begins on this day. The observance of the Samprapti Dwadashi Vrat continues on every Krishna Dwadashi up to the Jyeshtha month. Thereafter, the fast is observed again from the Ashadha to Margashirsha month. This Vrat is believed to fulfill rare desires and bestow both material and spiritual prosperity upon the devotee.
For the detailed procedure of this Vrat, refer to the Matsya Dwadashi observed on Margashirsha Shukla Dwadashi.
