Alright kiddo, so public holidays in Thailand are days that everyone gets to take a break from work or school and have fun with their families and friends. In other words, they are like your birthday, Halloween, and Christmas but for the whole country!
There are many public holidays in Thailand, like New Year's Day (January 1st), Songkran (April 13th to 15th), which is like a big water fight festival, and National Day (December 5th), which celebrates the birthday of the King.
These holidays are really important to Thai people because they get to spend time with their loved ones and celebrate their culture and history. During these holidays, you might see lots of people parading in the streets, eating special foods, or going to temples to pray.
So, the next time you hear someone saying they are on holiday in Thailand, you'll know that they are taking a day off to enjoy some fun festivities and spend time with their family and friends.
