Crown Prince Willem-Alexander turns 43 on 27 Apr. Bookies are taking bets on whether he will be king by his birthday, or will have to wait three days for the 30th anniversary of the investiture of his mother, Queen Beatrix---or even longer. Another question is whether he will change Queen's Day, the national day marking his mother's birthday on Apr 30, to King's Day when he eventually becomes king. If he does, it would only be a few decades before it is Queen's Day again. He has three daughters in line to the throne.
As the eldest child of Queen Beatrix, Prince Willem-Alexander, The Prince of Orange, is first in line of succession to the throne. Since his mother's investiture on 30 April 1980, he has borne the title Prince of Orange, which has been held by the heir to the throne since 1815. The Prince is married to Princess Máxima. They have three daughters, Princess Catharina-Amalia, Princess Alexia and Princess Ariane. He is Aide-de-Camp Extraordinary to Queen Beatrix.
