Loy Krathong is one of the biggest and most colorful celebrations in Thailand. People celebrate it during the 12th month of the Thai lunar calendar’s full moon. This year, Loy Krathong will be on November 8.
The celebration comes from the word “Loi,” meaning float, and “Krathong,” meaning a small vessel, container, or basket.
During the festival, people wear traditional Thai clothing and gather for festivities. Most significantly, they gather at night, setting off their candle and flower-decorated krathongs to rivers, lakes, beaches, and canals. With a beautiful spectacle of lights afloat, the festival has been called the “Thai Festival of Lights.”
The practice allows the Thais to pay their respect to Mae Khonhkha, the water goddess. They also believe the tradition can rid themselves of bad luck and bring good luck.
