I like the Loy Krathong festival the most. It is a festival in November where Thai people use the krathong to thank the Goddess of Water. Loy Krathong Day is one of the most popular festivals of Thailand celebrated annually on the Full-Moon Day of the Twelfth Lunar Month. It takes place at a time when the weather is fine as the rainy season is over and there is a high water level all over the country.
