On Visakha Bucha Day, Thai Buddhists and Buddhists all over the world commemorate three great events: The birth, enlightenment and the passing away of Gautama Buddha. The Buddha was born on this day in Lumpini. On this day, 35 years later, he attained enlightenment in Buddhagaya, India. Also on this day, 80 years from his birth, the Buddha passed away in Kusinara (Kushinagar), India. Traditional religious rites on day, includes merit-making (by offering alm to monks or visiting temples), observing of the 5 precepts, and meditation.
Recognized as most important memorial day in Buddhism, The Visakha Bucha Day reminds Buddhists the important of Lord Buddha's teachings, both spiritually and socially. The day marks the same day - the full moon night of the sixth lunar month - when Lord Buddha was born into this world, attained enlightenment 35 years later, and passed away when he was 80.
Visakha Bucha Day is recognized by the UNESCO on December 13, 1999 as "World Heritage Day".
