King Charles III was born on November 14th 1948 in Buckingham Palace. He ascended to the throne following the death of his mother, Queen Elizabeth II on Thursday September 8th 2022.

Despite the November birthday, the day is usually in June in the UK. This is because having a summer birthday means a higher chance of good weather in England during the Trooping the Colour parade for the monarch's birthday.

The King is the monarch of 15 countries, the United Kingdom and 14 commonwealth realms.

Since 1748, the monarch's official birthday has been marked by an outdoor parade known as Trooping the Colour which was usually held on the king or queen's actual birthday. Edward VII, who reigned from 1901 to 1910, was born in November. Instead of making the troops parade on a cold and dark November morning, the tradition began of celebrating his birthday officially in May or June as there was less chance of it being chilly and drizzly during the event. This tradition was then carried on by subsequent monarchs.
