The Queen celebrates two birthdays. Her actual birthday is 21 April, this year she will be 90. The Queen’s official birthday is second Saturday in June. The official birthday is held in the summer, so celebrations are less affected by the weather. On her official birthday, Her Majesty is joined by other members of the Royal Family at the spectacular Trooping the Colour parade which moves between Buckingham Palace, The Mall and Horseguards’ Parade as well as a public appearance on the balcony of Buckingham Palace.
