Asahna Bucha is a national Holiday in Thailand.
Buddhist Lent.
This day, the first full moon of the eighth lunar month commemorates the Buddha’s first sermon in the Deer Park in Benares, India and the founding of the Buddhist sangha (monkhood) about 2,500 years ago.
To mark the day, ceremonies are held in Buddhist temples across Thailand. Many Thai people return to their ancestral homes to donate offerings to temples and listen to sermons. Traditionally, candles are amongst the items donated to the wat for Asahna Bucha and processions featuring candles are held at various towns in Thailand.
