At what exact time will Donald Trump become President?
Noon local time (5pm GMT) on 20 January is the point of no return, when Donald Trump will take the Oath of Office.
Chief Justice John Roberts of the US Supreme Court will administer the oath on the steps of the United States Capitol Building.
The exact moment that trump becomes President will be when he utters the last word of the oath, which 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.
How many people are expected to attend - and which VIPs are invited?
The D.C. Department of Homeland Security and Emergency Management is planning for 800,000 to 900,000 people to attend the inauguration festivities. You can expect bikers to be in the crowd...
All the former presidents and their spouses are currently down to attend, so you will see Jimmy Carter, George W Bush, Bill Clinton and – as his wife – Hillary Clinton. George Bush Sr, the oldest living former president, is currently recovering in hospital after suffering from shortness of breath.
Barack Obama is also expected to be there - not going would make him the first president for 96 years to make such a snub.
Who is actually performing?
Presidential inaugurations have historically had a pretty stellar line up - Aretha Franklin and Beyonce both performed for Obama, while past presidents have had Bob Dylan, Barbara Streisand, Frank Sinatra... the list goes on.
In contrast, Trump has built up an impressive roster of rejections. Celebrities who have reportedly turned down the gig include Elton John, Celine Dion, Moby and Charlotte Church. Most recently, the Bruce Springsteen tribute band pulled out.
So, who is actually playing? Well, there's a band that apparently sound a bit like Nickelback called 3 Doors Down. Then there's Jackie Evancho who came second in American’s Got Talent. And also a handful of country singers.
When does Donald Trump move into the White House?
The White House handover immediately follows the inaugural parade. On the morning of 20 January, Barack Obama will wake up in the White House for the last time. That night, Donald Trump will sleep for the first time in his new home.
Will Donald Trump take over the @POTUS Twitter handle?
Because one account owned by Donald Trump on Twitter clearly isn't enough - it appears that the new President will be using both his personal account (@realDonaldTrump) and the official @POTUS handle. Twice the fun.
This information came to light in an interview with Michael Gove in the Sunday Times, with Trump saying he likes using his own Twitter.
"The tweeting, I thought I'd do less of it, but I'm covered so dishonestly by the press, so dishonestly, that I can put out Twitter - and it's not 140, it's now 280 - I can go bing bing bing . . . and they put it on and as soon as I tweet it out," he said.
Where will Obama go after the ceremony, and what will his new job be?
After eight years in the White House, Obama is jetting off for some rest and relaxation in sunny Palm Springs. His journey there will be his last ride in Air Force One. “Here's one thing: I'm not setting my alarm,” Obama told CBS.
As for his long-term plans, he will remain in Washington until his youngest daughter Sasha finishes school in 2019. Obama is also expected to take on a guidance role for the next generation of Democrat leaders.
“What we’ll be most interested in is programming that helps the next Michelle Obama or the next Barack Obama, who right now is sitting out there and has no idea how to make their ideals live, isn’t quite sure what to do - to give them resources and ways to think about social change,” he told The New Yorker.
Obama is likely to spend more time on his initiative My Brother’s Keeper, as well – which creates a mentoring system for young black men. He also may step up his work with Organizing for Action, a grass roots effort formed from the president’s 2012 re-election team, which focuses on climate change and immigration reform.
