Editing Vesak (section)

===Dates of observance===
The exact date of Vesak is based on Asian [[lunisolar calendar]]s and is primarily celebrated in [[Vaisakha]], a month of both the [[Buddhist calendar|Buddhist]] and [[Hindu calendar]]s, hence the name Vesak. In Nepal, which is considered the birth-country of Buddha, it is celebrated on the full moon day of the [[Vaisakha]] month of the [[Hindu calendar]], and is traditionally called Buddha Purnima, Purnima meaning the full moon day in Sanskrit. In Theravada countries following the [[Buddhist calendar]], it falls on Uposatha Day, the full moon typically in the 5th or 6th lunar month.

Nowadays, in Sri Lanka, Nepal, India, Bangladesh and Malaysia, Vesak/Buddha Purnima is celebrated on the day of the first full moon in May in the Gregorian calendar.

For countries using the lunisolar calendar, the date for Vesak or Buddha's Birthday varies from year to year in the Gregorian calendar, but usually falls in April or May; in leap years it may be celebrated in June. In Bhutan it is celebrated on the 15th day of the fourth month of the Bhutanese lunar calendar. In Thailand, Laos, Singapore and Indonesia, Vesak is celebrated on the fourteenth or fifteenth day of the fourth month in the Chinese lunar calendar. In China, Korea, Vietnam and the Philippines, [[Buddha's Birthday]] is celebrated on the eighth day of the fourth month in the Chinese lunar calendar. In Japan, Buddha's Birthday is observed on the same date but in the Gregorian calendar, i.e. 8 April.

In Myanmar, Buddha's Birthday is celebrated as '''Full Moon of Kasun''' and is a public holiday. It is celebrated by watering the Bodhi tree and chanting. In large pagodas, music and dance is also performed as part of the celebrations.
