The Coronation will no doubt see King Charles and Queen Camilla as stars of the show.
But giving them a run for their money will be their young pages - not least the youngest of the boys, Prince George.
The nine-year-old will be a page for his grandfather the King and will have the responsibility of helping to carry his robes.
It may be a daunting task for the second in line to the throne as the eyes of the world will be upon him.
And it's believed his parents William and Kate, the Prince and Princess of Wales, thought long and hard about allowing George a part in the ceremony.
But they agreed after he reportedly showed an interest in the Coronation and according to royal expert and author Ingrid Seward, his parents will be teaching him about the Coronation in preparation for the big day.
Here she gives her take on how preparations will have been taking shape.
Easter lessons
Ingrid explained to the Mirror: "As one of four Pages of Honour, the nine-year-old will have had to learn about the six stages of his grandfather’s coronation in preparation for the big day.
"Over the Easter holidays Catherine will have been teaching not just George, but all three of the children a simplified version of what they will be witnessing on the day.
"The recognition, the oath, the anointing, the investiture (which includes the crowning) the enthronement and the homage."
Fun re-enactments
So how can William and Kate teach their children? Well according to Ingrid: "By making it fun and by re-enacting parts of what their grandfather will be doing both she and William hope George won’t be too daunted by his responsibilities.
"He will form part of the King's Procession with the three others through the nave of Westminster Abbey."
Virtual tours
And when it comes to getting used to the vast building that is Westminster Abbey, where the Coronation takes place, William and Kate will use their computer.
Ingrid explained: "There are no actual rehearsals until much nearer the time and instead they have been advised to use the virtual online tour of the Abbey as a guide for George.
"If he can visualise where he is supposed to go and what to do, it will reduce any nerves he might feel being the youngest page. The other three boys are 13 and 12 respectively."
'Fancy' outfit
But one thing George will definitely have to get used to is his outfit, likely to be a red coat with white breeches and buckled shoes.
Ingrid added: "He will also have to get used to the idea of wearing the red-coated livery and lace of a page of honour as I can't see him going in a jacket and tie.
"Prince Michael of Kent, who was 11 at the late Queen’s Coronation, recalls his buckle shoes and dark green velvet jacket and how his schoolfriends teased him about wearing ‘fancy dress.’ No doubt George has had a bit of teasing too.
"But on the day, he will have the last laugh over his friends. When they watch on TV he will be there and they won’t. He will certainly never forget it."
