Visakha Bucha in Various locations
Visakha Bucha, known internationally as Vesak, is Thailand's most important Buddhist holiday, commemorating the Buddha's birth, enlightenment and death together on the full moon of the sixth lunar month, usually May. It is observed nationwide through temple visits, candlelit processions and merit-making rather than a single localized festival site.
Visakha Bucha, widely known outside Thailand by its Pali-derived name Vesak, stands as the single most important date on the Buddhist calendar in Theravada countries, and Thailand observes it with the reverence its scale deserves.
