The royal family’s calendar already has King Charles III’s coronation date highlighted for another purpose.

The new King will be formally crowned on May 6, 2023, the same day his grandson Archie Harrison turns four, according to a statement from Buckingham Palace on Tuesday.

It was commonly assumed that King Charles would choose June 2 to celebrate the date of Queen Elizabeth’s coronation in 1953, however the actual coronation took place earlier in the year than was anticipated.

The palace announced that Queen Camilla will be crowned alongside her husband. “The Coronation will represent the monarch’s role today and look towards the future, while being entrenched in longstanding traditions and pageantry,” the palace added. In accordance with royal custom, the event will begin at Westminster Abbey in London.

The ceremony will start in Westminster Abbey in London, where British kings and queens have been crowned for the last 900 years, in keeping with royal custom.

The coronation is the second major royal event to coincide with a small child’s birthday weekend since Prince Harry and Meghan Markle became parents.

The ceremony, according to the palace, will be “based in long-standing traditions and pageantry” while “reflecting the monarch’s function today and looks toward the future.”

Although it may be doubtful given that it comes on a weekend, it has not yet been determined whether a bank holiday will be observed to commemorate the occasion.

On June 2, 1953, the Queen was crowned in a ceremony that lasted three hours and included 8,000 dignitaries. The occasion was streamed live on tv.

Thousands of people lined the streets back then to catch a glimpse of the Queen traveling in the gold state carriage, which has been a tradition since George IV’s coronation.

Whether the coach will be utilized this time is unknown.
