On January 20 (January 21 AEDT), Donald Trump will be sworn in as the 45th President of the United States of America as the billionaire businessman will officially take his oath of office in a Presidential Inauguration which has a long history dating right back to the United States’ first president, George Washington.

When is everything happening?
Here’s what time you can expect everything to happen on Inauguration Day. Some of the exact times have yet to be officially finalised, so treat these as a rough guide.

Saturday, 1:00am AEDT (Australian Eastern Daylight Time)

The President-elect attends a morning worship service.

Saturday, 1:30am AEDT
The Inaugural Swearing-in Ceremony begins. The crowd will be entertained by performers until the President-elect arrives.

Saturday, 2:30am AEDT
President-elect Trump heads to the White House for a meeting with soon-to-be former President Barack Obama. From there, they head to the swearing-in ceremony at the US Capitol together.

Saturday, 3:45am AEDT
Incoming vice-president Mike Pence takes his oath of office first.

Saturday, 4:00am AEDT
At noon (local time), the term of the new administration officially begins. Mr Trump will step up and take the oath of office, administered by the Chief Justice of the United States, John Roberts.

It reads: “I do solemnly swear (or affirm) 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.”

From this point onwards, we’re in the term of President Trump.

Saturday, 4:10am AEDT
President Trump will step up to the lectern to deliver his Inaugural Address. Both of Barack Obama’s inaugural addresses ran for about 20 minutes each.

Saturday, 5:00am AEDT
After the conclusion of the inaugural ceremony, it’s time to farewell Barack Obama and Vice-President Joe Biden (as well as their families).

They’ll be escorted out by the new President and Vice-President. Since the ’70s, the former president and first lady have left the Capitol grounds by a helicopter, if weather permits.

Saturday, 5:30am AEDT
It’s time to have a break and grab something to eat.

The Inaugural Luncheon is organised by the Joint Congressional Committee on Inaugural Ceremonies and normally features food from the states of the new President and Vice-President (that’s New York and Indiana for those playing along at home).

Saturday, 6:30am AEDT
After lunch, President Trump and Vice-President Pence lead the Inaugural Parade along Pennsylvania Avenue to the White House.

Members of the public will line the street, so expect plenty of well wishers and protesters as well.

The Inaugural Committee has announced there will be more than 8,000 participants marching in this year’s parade.

Saturday, 11:00am AEDT
The day finishes with Inaugural Balls held across Washington. Trump has announced he’ll attend two official balls on the night.
