On April 27th, the Dutch are celebrating the birthday of their king: King Willem-Alexander. It is the day when the whole country turns orange and goes crazy to celebrate his birthday. During King's Day, there are a wide variety of events happening all over the country. From small activities for kids to big festivals with the best DJs. If you want to spend a full day doing all kind of stuff, it's best to visit one of the five most active King’s Day cities: Amsterdam, Rotterdam, The Hague, Utrecht, and Eindhoven.
King's Day traditionally starts with flea markets happening everywhere. It's the one day per year that it's allowed to set up shop on the streets without the need of a trading license. Kids and adults alike use this day to sell their old stuff and earn a few extra euros.
