Loi Krathong festival is a Thai tradition which has been conducted for a long time ago. Loi Krathong has been held since the middle of the eleventh to the middle of the twelfth lunar month, which is a great flood season- especially on the full moon night of the twelfth lunar month. When the moon shines at night, it makes rivers clear. It is very beautiful scenery which is suitable for floating krathong.
