The Dutch are donning crazy orange-colored outfits and celebrating their first ever "King's Day" — a national holiday held in honour of the Netherlands' newly installed monarch, King Willem Alexander.
The festival began Friday evening for hard core partiers and climaxes Saturday, with open-air markets and concerts around the country. More than a million people are expected to attend in Amsterdam alone.
King's Day replaces the traditional "Queens' Day" festival held this time of year, and not much else will change. It's been renamed because Willem Alexander, who assumed the throne last year, is the first male monarch from the Netherlands' ruling House of Orange in living memory.
The king and his wife Queen Maxima are visiting the scenic village of De Rijp, 36 kilometres (22 miles) north of Amsterdam.
