The religion known as Buddhism dates back to the 6th or 5th Century BCE, when the Indian Prince Siddhartha Gautama became the “Buddha,” literally, “the Enlightened One.” The followers of the Mahayana branch of Buddhism observes Bodhi Day in celebration of the day that the Buddha sat below the Bodhi Tree and meditated on the meaning of life. Bodhi Day is celebrated mainly by the Buddhists of northern and eastern Asia (in Japan the day is known as Rohatsu) and in countries to which those people have immigrated (such as Canada).
