Buddha’s Birthday is observed in East Asia, particularly in Macau, Hong Kong, and South Korea, every year on the 8th day of the 4th month in the Chinese calendar. This holiday celebrates the birth of Prince Siddhārtha Gautama, the founder of Buddhism, who was born in Lumbini, present-day Nepal. According to tradition, Siddhartha’s father, King Śuddhodana, sought to shield him from the suffering of the outside world, but Siddhartha eventually ventured out, leading to his spiritual quest and attainment of nirvana. In Korea, the festival is marked by decorating temples with lotus lanterns, and many temples provide free meals and tea to visitors on this day. Buddha’s Birthday serves as an official public holiday in the aforementioned regions, reflecting the cultural and religious significance of this event in the Buddhist community.
