King Charles III ascended the throne after Queen Elizabeth's demise on September 8. A Principal Proclamation followed on September 10, but when will the formal coronation happen?

King Charles is now the U.K.'s monarch, but his coronation will not happen until next year. Why? Aside from the royal family and the public still mourning, there are preparations they must make.

Express noted that His Majesty has returned to Scotland after his mother's funeral on September 19. He's now privately mourning at Balmoral.

As he became the king, he promised to work hard to follow the inspiring example of the late Queen in "upholding constitutional government." So, when the time comes that he will finally take the crown, he will be ready.

The royal family's official website describes the much-awaited coronation as an "occasion for pageantry and celebration." It will require him to take a coronation oath.

The site explains the coronation usually happens months after the accession and once the mourning period, which lasts for a week after the funeral, has ended. In this case, the mourning will end on September 26.

Of course, a lot of preparations are needed, and doing it after the funeral makes it trickier. With that said, King Charles' coronation may not occur until the spring or summer of 2023.

So, what will happen at the special event? The Telegraph added the coronation would fit King Charles' plan to have a smaller and more modern monarchy.

He will be crowned with his wife, Camilla, Queen Consort of the United Kingdom. The ceremony will also be shorter, smaller, and less expensive than Queen Elizabeth's.

The event will reportedly be graced by representatives of different faiths and community groups, granting King Charles' request to show modern Britain's ethnic diversity.

The coronation will see the delivery of the oath required by statute. It will also include the anointing with consecrated oil, the delivery of the orb, and the enthroning.

King Charles will be crowned with the St. Edward's Crown, witnessed by only 2,000 people-a complete opposite of Queen Elizabeth's 8,000 guests. The event will be conducted by the Archbishop of Canterbury in Westminster Abbey.

The new king will be seated in the Coronation Chair, called Edward's Chair, and hold the sovereign's scepter and rod to represent his control of the nation and the sovereign orb to signify the Christian world. After the anointing, King Charles will wear the crown of St. Edward on his head, making him the official king of Britain.
