King Charles III has taken on new responsibilities since he acceded the throne upon the death of his mother, Queen Elizabeth II. Like the late Queen, the former Prince of Wales will have a chance to celebrate two birthdays each year as per a royal tradition which was introduced 250 years ago.
The new King of the United Kingdom and 14 other Commonwealth realms will celebrate his 74th birthday on November 14 - but next year, he could celebrate two with the other being in June. Since 1748, Kings and Queens have marked their special day with the Trooping the Colour parade.
