this is a good example of one of the traditions carried out in various areas of the country on this holiday. I can not take credit for this amazing photo though. We just had floats.
Loy Krathong is held on the full moon of the 12th month in the
traditional Thai lunar calendar. In the western calendar this usually
falls in November.
"Loi" means "to float". "Krathong" is a raft about a handspan in diameter traditionally made from a section of banana tree trunk (although modern-day versions use specially made bread 'flowers' and may use styrofoam), decorated with elaborately-folded banana leaves, flowers, candles, incense sticks etc. During the night of the full moon, many people will release a small raft like this on a river. Governmental offices, corporations and other organizations also build much bigger and more elaborate rafts, and these are often judged in contests. In addition, fireworks and beauty contests take place during the festival.
