In this question the reason for celebrating Holi was asked but the answer given is based on wikipedia which also says:
The Holika bonfire and Holi signifies the celebration of the symbolic victory of good over evil, of Prahlada over Hiranyakashipu, and of the fire that burned Holika.
Considering that the Holika dehan or burning of Holika is celebrated on the eve of Holi, the logical conclusion would be that the next day is concerned with the celebration of her brother Hiranyakshipu's death at the hands of Lord Narasimha. But the Narasimha Jayanti is celebrated on Vaishakha Shukla Chaturdashi while Holi falls on Phalgun Purnima.
So my question is - Is the festival of Holi related to the death of not just Holika but also Hiranyakshipu & do the scriptures mention an association between Narasimha and Holi?
