|Buddh Poornima is the most sacred day in the Buddhist calendar. It is a day to celebrate the birth anniversary of Buddha, the founder of Buddhism. It is the most important festival of the Buddhists, and is celebrated with great enthusiasm and fervor. It is celebrated on the full moon night in the month of either April or May. This festival has special significance because on this day the Buddha was born, attained enlightenment, and also attained Nirvana when he died. This strange and extraordinary, three - fold coincidence, gives Buddha Poornima its exclusive importance.
