Buddh Purnima, also known as Buddha Purnima, Buddha Jayanti, or Vesak, is a highly revered annual holy day in Buddhism worldwide. It commemorates three significant events in Śākyamuni Buddha’s life.
Birth
Remembering Lumbinī, where Emperor Aśoka erected an edict pillar.
Awakening
Honoring Bodh Gayā, where the Buddha attained enlightenment.
Parinirvāṇa
Reflecting on the final passing at Kuśinagar / Kusinārā.
The festival is usually celebrated on a full-moon day in the lunar month of Vesākha / Vaiśākha, generally falling in April or May. In 1950, the World Fellowship of Buddhists recommended that governments recognize the May full moon as “Buddha Day,” a practice later adopted globally by the United Nations.
