The nation will come together this Saturday, June 14, to celebrate King Charles's official birthday in London. Trooping the Colour is held annually as an official birthday event for the monarch, even though Charles's actual birthday is on November 14. It dates back centuries and became an annual event in 1760.

It is one of the biggest military ceremonies of the calendar and this year it will feature more than 1,400 parading soldiers, 300 musicians and over 200 horses. The spectacle will wrap up with an RAF flypast over Buckingham Palace, which the Royal Family, including the Prince and Princess of Wales as well as their children, will watch from the Palace balcony.
