Buddha Jayanti, also known as Buddha Purnima or Buddha's Birthday, is a significant Buddhist festival celebrated to honor the birth, enlightenment (nirvana), and passing away (parinirvana) of Siddhartha Gautama, who later became known as Gautama Buddha—the founder of Buddhism. This festival holds immense religious and cultural importance for Buddhists worldwide and is observed on the full moon day in the Nepali month of Jestha, which usually falls in April or May in the Gregorian calendar. Lumbini, located in Nepal, is traditionally recognized as the birthplace of Siddhartha Gautama. On Buddha Jayanti, pilgrims from various parts of the world visit Lumbini to pay their respects and offer prayers at the sacred site.
