Koningsdag
The King's Day is the most important national holiday in the Netherlands, and it is celebrated on April 27th (the birthday of King Willem-Alexander). The celebration includes the vrijmarkt (a nationwide flea market where anyone can sell anything on the street), the oranjegekte (orange madness, when everyone wears orange clothing and accessories), and the koningshavermout (the traditional oatmeal with fresh strawberries). The vrijmarkt is the most democratic tradition in the Netherlands: for one day, anyone can set up a stall on the street and sell anything. The streets are full of children selling their old toys, students selling their old books, and artists selling their paintings. The King's Day is not just a birthday party. It is the celebration of the Dutch national identity, and the orange is the color of the House of Orange-Nassau (the royal family). The royal family visits a different city each year, and the local children perform traditional dances and songs. The orange color comes from the name of the royal house: Orange-Nassau, which traces its origins to the Principality of Orange in southern France.
