Bodhi Day

Culture/religion: Buddhist
Date: December 8
Bodhi Day is one of the most significant events in the Buddhist faith, commemorating Buddha’s enlightenment. Bodhi means “awakening,” or as translated in English, “enlightenment.”
As the story goes, the historical Buddha was a prince named Siddhartha Gautama who decided to give up his privileged life to seek peace of mind. After six years of frustration he sat under a fig tree and vowed to remain in meditation until he fulfilled his quest. During this meditation, the prince realized enlightenment and became Buddha, or “the one who is awake.”
With varying Buddhist traditions in different regions, Bodhi Day has a variety of names and dates of observance. Theravada Buddhists celebrate it as Vesak which is observed by a lunar calendar with changing dates, and usually falls in May. Tibetan Buddhism observes Buddha’s birth, death and enlightenment all at the same time, calling it Saga Dawa Duchen. Mahayana Buddhists celebrate the events on three different holy days.
Bodhi Day is observed quietly with meditation or chanting, and an informal commemoration may include bodhi tree decorations or simple tea and cookies.
