Here are the main holidays and festivals in Thailand, as they are celebrated by the majority of Thai people (we didn't include regional festivals or minor Chinese festivals). We have organized the list month by month, so you can easily check what are the main celebrations in Thailand while you are visiting.
Children's day is celebrated on the second Saturday of January. On this special day many events are held for children, and parents take their children out, for instance to amusement parks.
On Teachers' Day, all pupils will pay respect to their teachers during a ceremony at school. In Thailand teachers are still very respected, contrary to Europe.
Around 10% of Thai people are of Chinese descent, and the Chinese New Year is a big event. If you are in Bangkok, dress in red and join the celebrations in Chinatown!

Loy Krathong happens on the first full moon day of November.
