His Majesty King Charles III will be proclaimed as Lord of Mann at Government House at 12 noon on Sunday September 11.
The proclamation will be read by the Lieutenant Governor.
Government says the public are able to attend, although there is only limited on-site parking.
Therefore, members of the public are encouraged to attend a second ceremony at Tynwald Hill in St John's at 11am on Friday September 16.
Following this, a resolution of loyalty and condolence will be put before a sitting of Tynwald Court.
This ceremony is based on the one held in 1952 to proclaim Queen Elizabeth II, and is similar to the normal Tynwald Day Ceremony.
