Vesak (Pali: Vesākha, Sanskrit: Vaiśākha), also known as Buddha Purnima and Buddha Day, is a holiday traditionally observed by Buddhists and some Hindus on different days in India, Sri Lanka, Nepal, Tibet, Bangladesh, Bhutan, Indonesia, Singapore, Thailand, Cambodia, Laos, Malaysia, Myanmar, Mongolia and the Philippines and in China, Japan, South Korea, North Korea, Taiwan and Vietnam as "Buddha's Birthday" as well as in other parts of the world. The festival commemorates the birth, enlightenment (Buddhahood), and death (Parinirvāna) of Gautama Buddha in the Theravada or southern tradition.

The decision to agree to celebrate Wesākha as the Buddha’s birthday was formalized at the first conference of the World Fellowship of Buddhists held in Sri Lanka in 1950, although festivals at this time in the Buddhist world are a centuries-old tradition. The resolution that was adopted at the World Conference reads as follows:

That this Conference of the World Fellowship of Buddhists, while recording its appreciation of the gracious act of His Majesty, the Maharaja of Nepal in making the full-moon day of Vesak a Public Holiday in Nepal, earnestly requests the Heads of Governments of all countries in which large or small number of Buddhists are to be found, to take steps to make the full-moon day in the month of May a Public Holiday in honour of the Buddha, who is universally acclaimed as one of the greatest benefactors of Humanity.
