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.

Inauguration Day didn’t always take place in January. Initially, Congress intended for the day to be honored in March.

President-elect Trump and his family departed Florida, beginning a historic return to Washington, D.C., for his second presidential inauguration.
