The birthday of the historical Buddha, also known as Vesak in many countries, commemorates the birth of Prince Siddhartha, who later became the Buddha, around the end of the 4th century B.C. This significant occasion is celebrated on varying dates depending on the school of Buddhism or country of observance.
In several Asian countries, Vesak is observed on the eighth day of the fourth month of the lunisolar calendar, falling on May 15 this year. In South and Southeast Asian countries, it is celebrated on the first full moon of May, which falls on May 23.
