The coronation of King Charles III will be marked with events across the country and thousands are expected to travel to London to catch a glimpse of the processions.
A weekend of events have been planned but the actual coronation takes place at Westminster Abbey from 11am on Saturday, May 6.
The service will be conducted by the Archbishop of Canterbury and it has been described as reflecting the Monarch’s role today as well as looking towards the future, while being rooted in longstanding traditions and pageantry.
Here is some of the details we know so far:
The Procession
The King and Queen Consort Camilla will arrive at Westminster Abbey in procession from Buckingham Palace, known as The King’s Procession.
After the ceremony, the journey will be the reverse of the King and Queen Consort's route to the Abbey but much shorter than Elizabeth II's five-mile return expedition around central London which saw the 27-year-old monarch waving to crowds along Piccadilly, Oxford Street and Regent Street. The King's Coronation Procession stretches to just 1.3 miles - around a quarter of the length of the late Queen's.
A newly crowned Charles and Queen Consort will make their way back from Westminster Abbey in the Gold State Coach via the tried and tested route of Parliament Square, along Whitehall, around Trafalgar Square, through Admiralty Arch and down The Mall back to Buckingham Palace.
More than 6,000 members of the armed forces will take part on the day of the coronation - the largest military ceremonial operation for 70 years - staging gun salutes and a flypast, and parading in the processions.
Some 4,000 sailors, soldiers, aviators and other military personnel from across the UK and the Commonwealth will accompany Charles and Camilla on their return Coronation Procession.
Flanking the roads will be more than 1,000 route liners from the British Army, RAF and Royal Navy.
The grand procession in 1953 took two hours and featured tens of thousands of participants, with the two-and-a-half mile cavalcade taking 45 minutes to pass any given point. Charles's shorter route is understood to have been chosen for practical reasons, with a preference for the familiar journey used on many a royal occasion.
Coronation roles revealed
From members of the Armed Forces, to faith leaders and Dukes and Earls from across the country, the list of people making the big day possible is fairly comprehensive.
Among them are former MI5 chief Baroness Elizabeth Manningham-Buller, who will carry St Edward's Staff, and former children's TV presenter, now author and peer, Baroness Floella Benjamin, tasked with carrying the Sovereign's Sceptre with Dove in the procession to the altar.
More than 50 people, including representatives from orders of chivalry, the military and wider public life, have been chosen to take part in the historic proceedings, and were selected to represent the nation due to their significant service, the Palace said.
Although Buckingham Palace is yet to confirm the exact roles for each member of the royal family during the coronation, we're expecting to see Prince William, Kate Middleton and future heir Prince George in prominent roles on the day.
Bank holiday
The bank holiday falls on Monday, May 8, following the Coronation ceremony on the Saturday.
In line with the bank holiday to mark Queen Elizabeth's Coronation in 1953, this will be an opportunity for families and communities across the country to come together to celebrate.
This year, members of the public will be invited to take part in The Big Help Out on the Monday, which will encourage people to try volunteering for themselves and join the work being undertaken to support their local areas.
