King's Night Amsterdam in Amsterdam
Koningsnacht, or King's Night, is the evening before King's Day, when Amsterdam's bars, clubs and public spaces fill with music and street celebration ahead of the following day's official festivities. In 2026 it falls on Sunday, April 26, the night before King's Day itself on Monday, April 27, the birthday of King Willem-Alexander.
For decades, the last day of April was fixed in the Dutch calendar as Queen's Day, a national holiday celebrating the birthday of Queen Juliana on April 30.
