Koningsdag is celebrated as a national holiday in the Netherlands (including some communities in the Caribbean). On this day, the Dutch celebrate the birthday of the king or the queen. Many Dutch people dress in orange (the colour of the royal house) for the occasion and celebrate nationally with parades, folk festivals and concerts. For Willem-Alexander’s birthday, Koningsdag is celebrated on April 27th. For everyone celebrating Koningsdag, we wish you a fun and peaceful celebration.
