Upon the passing of his mother, Queen Elizabeth II on Thursday, her eldest son, Prince Charles, automatically became King Charles III. However, the title was passed down without a coronation ceremony—and those who have wondered if such a ceremony will soon take place may be left waiting longer than expected if they want to witness it.

As it turns out, while Charles has now officially assumed the role of King, the celebration that marks his reign will likely be set for a much later date, as royal protocol doesn't allow for it to happen until after the mourning period of the previous sovereign.

"The coronation of the new Sovereign follows some months after his or her accession, following a period of mourning and as a result of the enormous amount of preparation required to organise the ceremony," the Royal Family website states.

Queen Elizabeth II ascended the throne upon the passing of her father, King George VI, on Feb. 6, 1952, but was not coronated until June 2, 1953—16 months later. While it is unclear if Charles will wait that same period for his coronation, those waiting to watch shouldn't expect it any time soon.

The official mourning period for the Queen consists of 10 days and will last until after her official funeral takes place at Westminster Abbey. Despite not being coronated until the date that is decided upon, an Accession Council consisting of politicians, bishops and senior civil servants proclaimed his Succession on Saturday.

While the pomp and circumstance of his coronation are yet to happen, the Royal Family has moved quickly when it comes to their future. Not only did Charles officially become King and his wife, Camilla, become the Queen Consort, but Prince William and Kate Middleton also assumed new titles. They have now assumed the titles previously held by the King and Queen Consort, which included both the Duke and Duchess of Cornwall and the Prince and Princess of Wales. Middleton is the first woman to hold the Princess of Wales title since Princess Diana.

The change in titles also affects their children, Prince George, Princess Charlotte and Prince Louis. Not only did all three once again move up in the royal line of succession, but their last names now reflect their parents' new titles. Instead of using Cambridge as a surname, they will now all use the name Wales.

Though they have stepped back from the Royal family and reside in the United States, Prince Harry and Meghan Markle's children, Archie and Lilibet, are also now eligible for Prince and Princess titles, since their grandfather is now the King.
