Elizabeth Alexandra Mary of the House of Windsor was born on April 21, 1926.

The Queen usually spends her actual birthday privately, but the occasion is marked publicly by gun salutes in central London at midday: one in Hyde Park, another in Windsor Great Park and a third salute at the Tower of London.

The monarch's birthday has been an official celebration in the UK since 1748 when King George II reigned. Since 1959, the Queen Elizabeth II's Official Birthday has been on the second Saturday of June. 

On her official birthday, in June, the Queen makes a public appearance on the balcony of Buckingham Palace. Her Majesty watches the spectacular Trooping the Colour parade, also known as the Queen's Birthday Parade, in London with other members of the Royal Family. The parade moves between Buckingham Palace, The Mall, and Horseguards’ Parade.
