Buddha's Birthday is an official holiday in Hong Kong, Macao, and South Korea. The date varies from year to year in the Western calendar. The birth of the Buddha is often celebrated by Buddhists in India for an entire month in the Buddhist calendar. The actual day is called Buddha Poomima, also traditionally known as Vaishakh Poomima. The day marks not only the birth of Shaky amuni Gautam Buddha, but also the day of Enlightenment, and Mahaparinirvana. But as a gentle effect of West, the event of Birth is given paramount importance.
