Two months after stunning America and the world by winning the US election, Donald Trump will be sworn in as the 45th President of the United States.
He will replace Barack Obama in the White House, but not before a ceremony that dates back to George Washington.
The eyes of the world will be on Mr Trump as he takes the Oath of Office, and offers his inaugural address.
The Oath of Office
At noon local time (5 PM GMT) on January 20, Donald Trump will take the Oath of Office and be sworn in as America’s 45th president.
Chief Justice John Roberts of the US Supreme Court will administer the oath on the steps of the United States Capitol Building.
It will go something like this:
I Donald J Trump, do solemnly swear that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States, so help me God
Mike Pence, the vice president-elect, will take the oath shortly before Mr Trump.
