Mark your calendars: On April 26, 2014, the whole of the Netherlands will be celebrating King's Day. The springtime holiday is normally called Queen's Day, but in 2014—for the first time since 1890—the country will celebrate a male monarch: King Willem-Alexander. (King's Day will take place annually on Willem-Alexander's birthday, April 27, but since the holiday isn't celebrated on a Sunday, the festivities in 2014 will happen on April 26.)
What does it mean? Parties! It's a public holiday typically teeming with brightly decorated canal boats, outdoor dance parties, and live music. Check out 2013's Queen's Day roster here, and expect bigger and more raucous happenings during next year's historic celebration.
