Vesak (Sinhalese) is the most holy time in the Buddhist calendar. In Indian Mahayana Buddhist traditions, the holiday is known by its Sanskrit equivalent, Vaisakha. The word Vesak itself is the Sinhalese language word for the Pali variation, “Visakha”. Visakha/Vaisakha is the name of the second month of the Indian calendar. Vesak is also known as Visakah Puja or Buddha Purnima in India, Bangladesh and Nepal, Visakha Bucha in Thailand, Phat Dan in Vietnam, Waisak in Indonesia, Vesak (Wesak) in Sri Lanka and Malaysia, and Saga Dawa in Tibet. The equivalent festival in Laos is called Vixakha Bouxa and in Myanmar is called Ka-sone. Vesak is a public holiday in many Asian countries like Sri Lanka, Malaysia, Myanmar, Thailand, Singapore, Vietnam, and so on.
