Holi in the Punjab region originated in the city of Multan in the Prahlada-Puri Temple. The original temple of Prahladpuri is said to have been built by Prahlada, son of Hiranyakashipu, the king of Multan (Kashya-papura) in honor of Narasimha Avatar, an incarnation of Hindu god Vishnu, who emerged from the pillar to save Prahlada. Holi also marks the advent of spring. Holi is celebrated over two days with Holika dahan being observed on Phagan Purnima or Pooranmashi (Full Moon), and Holi itself being celebrated the next day on the first day of Chet according to the Punjabi calendar.
