Joe Biden is US president-elect. But the Democrat won't officially make his move to the White House until inauguration day - a political parade of sorts, when Mr Biden takes the oath of office.
Here's what you need to know about the big day.
What is the inauguration?
The inauguration is the event where the US president-elect and vice-president elect are sworn in.

"I 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."
This year it amounts to each lawmaker plus a guest. Some members of Congress have already opened up submission forms, with the caveat that nothing is guaranteed.
The Biden team has "strongly encouraged" people to refrain from travelling to Washington to attend, amid fears of virus spread.
In normal circumstances, DC would see hundreds of thousands - make that an estimated two million the year President Obama was sworn in - of inauguration revellers flock to the city, swarming the National Mall and selling out hotels.
