Now that the Queen's son has taken to the throne he will get two birthdays just like his late mum.
King Charles III having a second birthday will follow a 250 year old royal tradition. The former Prince of Wales is set to celebrate his 74th birthday in just two months time, on November 14, but next year he is likely to have a second birthday celebration, in June.
He is following in his mother's footsteps as her actual birthday was in April but she always had a second day to mark the occasion on the second Saturday in June. The event is marked with a Trooping the Colour parade in central London.

The tradition was first introduced in 1748. However, as Edward VII, the King who reigned from 1901 to 1910, was born in November the decision was made to move the parade to June in the 20th century. This was because there was less chance of it being cold and wet on the big day.
What is Trooping the Colour?
The Trooping of the Colour has marked the official birthday of the British Sovereign for over 260 years. Over 1,400 parading soldiers, 200 horses and 400 musicians come together each June in a great display of military precision, horsemanship and fanfare to mark the monarch's Official Birthday.
The parade moves from Buckingham Palace and down The Mall to Horse Guard's Parade, alongside Members of the Royal Family on horseback and in carriages. The display closes with an RAF fly-past, watched by Members of the Royal Family from Buckingham Palace balcony.
