A parade and visiting Navy ships will herald the swearing-in of Jersey's new Lieutenant Governor.
Vice Admiral Jerry Kyd will take his oath of office on Saturday (8 October).
His appointment was announced in May.
He officially begins his five year term of office as King Charles III's first representative on the island.
A special sitting of the Royal Court will convene at 9.45am, led by the Bailiff, Sir Tim Le Cocq.
It will be followed at 10.25am by a parade in the Royal Square.
HMS Severn will be in the island for the ceremony and open to the public on Sunday and Monday mornings 10am-12pm.
It will feature a ceremonial guard from HMS Iron Duke and marching platoon from HMS Severn, armed forces and cadets.
His Majesty's Band of the Royal Marines will also take part, and there will be an inspection by the new Lieutenant Governor, Bailiff and Deputy Bailiff.
At 11am there will be a service of dedication in the Town Church, led by the Dean of Jersey, the Very Reverend Mike Kierle.
Vice Admiral Kyd, who left the Senior Service in March of this year as Fleet Commander – a post second only to the First Sea Lord – becomes the first Royal Navy Lieutenant Governor of Jersey in 32 years when Admiral Sir William Pillar stood down.
"I am honoured to have been chosen to be His Majesty’s personal representative on island and am relishing the opportunity to play a full and active part in island life during my time in office. The island is a very special place and one both my wife and I are looking forward to calling home."
Jersey's previous Lieutenant Governor, Sir Stephen Dalton left the island in the summer.
The Royal Square was the scene of a farewell service for Sir Stephen and Lady Dalton in June.
