Koningsdag, or King’s Day, is the Netherlands’ most dynamic national celebration, held annually on April 27th in honor of King Willem-Alexander’s birthday. The entire country transforms into a sea of orange, symbolizing the Dutch royal family, the House of Orange.
Cities like Amsterdam, Rotterdam, and Utrecht come alive with street parties, music festivals, and flea markets where people sell everything from homemade crafts to second-hand goods. The festivities begin the night before with Koningsnacht (King’s Night), when bars and nightclubs host special events, keeping the party spirit alive until the early morning hours.
Beyond the parties, Koningsdag is also a day of tradition and community spirit. The royal family visits a different city each year, bringing national attention to local festivities. Families and children take part in fun fairs and traditional Dutch games like Spijker poepen (nail pooping) and Koekhappen (cake biting).
Meanwhile, the canals of Amsterdam become the heart of the celebration, packed with orange-clad revelers on boats. Whether enjoying a lively festival, exploring a vrijmarkt (flea market), or raising a glass of Oranjebitter, Koningsdag is a unique and unforgettable experience that showcases Dutch pride, unity, and love for celebration.
Koningsdag History

Koningsdag, originally known as Prinsessedag (Princess’s Day), was first celebrated in 1885 to honor the birthday of Princess Wilhelmina, the heir to the Dutch throne. After she became queen in 1890, the holiday was renamed Koninginnedag (Queen’s Day) and was officially celebrated for the first time on August 31, 1891.
Over the years, the tradition continued with each reigning queen, with the date later shifting to April 30 under Queen Juliana. The event developed into a nationwide celebration of Dutch culture and unity, with large street festivals and public gatherings.
In 2014, when Willem-Alexander became the first male Dutch monarch in over a century, the holiday was renamed Koningsdag (King’s Day) and moved to April 27, his birthday. Today, it remains the Netherlands’ most significant national celebration, bringing people together for parades, flea markets, and parties across the country.
