Visakha Bucha Day, Thailand

Held each year on the full moon of the sixth lunar month, Visakha Bucha Day celebrates the birth, enlightenment and death of Lord Buddha. On this day, Buddhists will go to the temple in worship and remembrance of the teachings and social and spiritual values of Buddha, and perform merit-making and candlelight ceremonies. This includes an evening Wien Tien candlelit procession where Buddhist devotees hold lighted candles in hand and go around a temple three times, representing one the Buddha, two his teachings, and three the monkhood.
