celebration of Vesākha

May 2007 just had two full moon days, the 1st and the 31st. Some countries (including Sri Lanka, Cambodia and Malaysia) celebrated Vesākha on the 1st, while others (Thailand, Singapore) celebrated the holiday on the 31st due to different local lunar observance. This difference also manifests in the observance of other Buddhist holidays, which are traditionally observed at the local full moon.

Likewise, in 2012, Vesak or the birth anniversary of the Buddha was observed on 28 April in Hong Kong and Taiwan, on 5 May in Sri Lanka, on 6 May in India, on 28 May in South Korea and on 4 June in Thailand. (In 1999 the Taiwanese government set Buddha's birthday as the second Sunday of May, the same date as Mother's Day.

On Vesākha day, devout Buddhists and followers alike are expected and requested to assemble in their various temples before dawn for the ceremonial, and honorable, hoisting of the Buddhist flag and the singing of hymns in praise of the holy triple gem: The Buddha, The Dharma (his teachings), and The Sangha (his disciples). Devotees may bring simple offerings of flowers, candles and joss-sticks to lay at the feet of their teacher. These symbolic offerings are to remind followers that just as the beautiful flowers would wither away after a short while and the candles and joss-sticks would soon burn out, so too is life subject to decay and destruction. Devotees are enjoined to make a special effort to refrain from killing of any kind. They are encouraged to partake of vegetarian food for the day. In some countries, notably Sri Lanka, two days are set aside for the celebration of Vesākha and all liquor shops and slaughter houses are closed by government decree during the two days. Also birds, insects and animals are released by the thousands in what is known as a 'symbolic act of liberation'; of giving freedom to those who are in captivity, imprisoned, or tortured against their will.[citation needed] Some devout Buddhists will wear a simple white dress and spend the whole day in temples with renewed determination to observe the eight Precepts.
