Inauguration Day 2017, the day Donald Trump assumed the role of chief executive of the United States, was Friday, Jan. 20, 2017. The nation's 45th president was sworn in on the steps of the U.S. Capitol at noon, when the term of President Barack Obama expired.

So how did Inauguration Day 2017 work?

Here are six things you need to know about the important day.

That's right: President Barack Obama was technically president of the United States right up until noon on Jan. 20, 2017, under provisions sets forth in the U.S. Constitution's 20th Amendment.

He was serving the final hours of his second term and completing a historic presidency as the nation's first African-American to serve in the White House. According to the amendment: "The terms of the President and Vice President shall end at noon on the 20th day of January."

Inauguration Day is replete with pomp and pageantry, including the traditional inaugural ball. These events have been held every four years since May 7, 1789, when the first inaugural ball was put on in honor of President George Washington. Modern-day inaugural balls cost tens of millions of dollars to put on, and there are usually way more than just one held the night of the new president's inauguration.

We try to shy away from making predictions about Election Day here, but this trend is difficult to ignore: Americans are fairly reluctant to elect consecutive presidents from the same political party. So if history is any indication, voters are likely to side with a Republican in 2016 after eight years under a Democratic president.

The last time voters elected a Democrat to the White House after a president from the same party had just served a full term was in 1856, before the Civil War. That president was James Buchanan, the 15th president and the only one ever to come from Pennsylvania. Buchanan succeeded President Franklin Pierce.

And Then There Will Be a Speech

Every president is expected to deliver an inaugural address, a speech whose purpose is to reunite an electorate that is still healing and divided from the election two months earlier, a speech that sets the course in policy and direction for the administration over the ensuing four years while acknowledging the work of the previous president.

"Civility," President George W. Bush said in his 2001 inaugural address, "is not a tactic or a sentiment. It is the determined choice of trust over cynicism, of community over chaos. And this commitment, if we keep it, is a way to shared accomplishment."
