The inauguration marks the official transfer of presidential power, with the executive branch changing hands from the Biden administration to the Trump administration. The 20th Amendment states that a president's four-year term ends at noon on Jan.

Will Trump take the opportunity this time, in his second inaugural speech, to talk of unity? Or will it be more 'American carnage'?

Under the Constitution’s 20th Amendment, the newly elected president of the United States takes office on Jan. 20 (unless that’s a Sunday, in which case it moves to Jan. 21). For Trump’s (second) big day, the pomp and circumstance will include performances by Carrie Underwood and the Village People, a military parade, and formal balls.
