Queen's Day, also known as 'Koninginnedag,' is celebrated in the Netherlands on April 30. The holiday honors the birthday of Queen Juliana, who ascended to the throne in 1948, and it continued to be observed on this date even after her daughter, Queen Beatrix, became monarch. The celebrations are particularly vibrant in Amsterdam, where the city transforms into a carnival-like atmosphere, attracting around 700,000 visitors each year. Participants, including shops and tourists, engage in festivities characterized by wearing orange clothing and accessories that symbolize the royal family. Although not a public holiday, many schools and businesses close for the occasion, contributing to the joyful and relaxed atmosphere. Queen's Day has been celebrated for over 50 years, marking a significant cultural event in the Netherlands.
