Step into the curious world of royal tradition as we explore the fascinating phenomenon of why kings have not one, but two birthdays.
King Charles III was born on November 14, 1948 making his actual birthday the 14th November, however since 1748 Trooping the Colour has marked the official birthday of the Sovereign - never mind when they were actually born. In theory this made sure their birthday celebrations took place when the sun shone...
Over 1,400 soldiers, 200 horses and up to 400 musicians take part in the parade, which processes from Buckingham Palace and down The Mall to Horse Guard’s Parade, together with members of the Royal Family on horseback and in carriages.
The parade ends with a now traditional fly-past by the RAF, which will be watched by the King and his family from the balcony at Buckingham Palace.
The list of Birthday Honours is also announced at the time of the monarch's official birthday celebrations.
But what we really want to know is does that mean he gets two lots of birthday presents a year?
