History of King's Day:Amsterdam celebrated King’s Day (Koningsdag) for the first time in 2014, after the inauguration of King Willem-Alexander on 30th April 2013 (what was then still Queen’s Day).The royal celebrations were first held on 31st August 1885 in honour of the birth of Queen Wilhelmina, and the Queen’s Day (Koninginnedag) tradition was born. After Wilhelmina’s daughter (Juliana) succeeded to the throne in 1949, the day was changed to 30th April in accordance with the new Queen's birthday.When she became queen, the now Princess Beatrix chose to retain the day in honour of her mother but as of 2014, King’s Day is officially celebrated on 27th April (the King’s birthday).The name may have changed slightly but the festive spirit of the day is sure to remain! You'll be treated to a sea of orange as everyone is covered head to toe in oranje(orange) as a show of pride for the Dutch Royal family, the House of Orange-Nassau.Every year, the royal entourage visits a town or municipality in the Netherlands as part of the celebrations.
