Nirvana Day is an annual Buddhist festival that remembers the death of the Buddha when he reached Nirvana at the age of 80. Nirvana is believed to be the end of the cycle of death and rebirth.

In 1330-1331 during the Yuan Dynasty, a large-scale bronze image of the Buddha attaining Nirvana was cast, and from that time on, the temple was popularly called the Temple of the Reclining Buddha.

Buddhism, founded by Gautama Buddha in the 6th century BCE, is one of the major world religions that focuses on the path to Nirvana (Enlightenment) through ethical living, meditation, and wisdom.
