The King's coronation will clash with an important family event tied to the Duke and Duchess of Sussex.
The royal ceremony is scheduled to take place on Saturday, May 6 at Westminster Abbey, ushering in a national bank holiday. The coronation will be the first in over 70 years and invites world leaders and dignitaries to take part in the event amid pomp and pageantry.
Members of the royal family will also receive invitations but a key member has been overlooked as the date of the ceremony clashes with their own special day. Charles' youngest grandson Archie may not be in attendance for several reasons, one being his parents' Prince Harry and Meghan Markle's strained relationship with the family, but also because it is his birthday.

Earlier this year, Buckingham Palace said the date was chosen in consultation with the Government, the Church of England and the Royal Household, but no further details have been given on why it was picked, the Mirror reported.
It comes following a period of rocky relations between Harry and his father the King since he and wife Meghan quit as working royals almost three years ago and moved to California.
Harry told US talk show host Oprah Winfrey he felt "really let down" by Charles, claimed he had stopped taking his calls in the run-up to the Megxit crisis and said there was a "lot of hurt".
He later lambasted Charles' skills as a father, criticising him for expecting his sons to endure the pressures of royal life, and suggesting his parenting left him with "genetic pain and suffering".
There has also been much discussion about Archie's title, with Meghan claiming he was wrongfully denied being made Prince, even though he couldn't technically get that title until the Queen died.
Charles’ accession to the throne means Archie and his one-year-old sister Lilibet, are technically a prince and princess. But it has not been confirmed yet by the Duke and Duchess of Sussex or Buckingham Palace if the youngsters will use these titles in the future.
Meanwhile, during the coronation ceremony, Charles will be anointed with holy oil, receive the orb, coronation ring and sceptre, be crowned with the majestic St Edward’s Crown and be blessed during the historic ceremony.
Camilla will also be anointed with holy oil and crowned, just like the Queen Mother was when she was crowned Queen in 1937.
Although the Palace said the ceremony would "reflect the monarch’s role today and look towards the future", it also added that it would be "rooted in longstanding traditions and pageantry".
