The 20th Amendment to the Constitution says, “The terms of the President and Vice President shall end at noon on the 20th day of January... and the terms of their successors shall then begin.” Inauguration Day, the day on which a new President takes office, includes an inaugural ceremony at the Capitol building in Washington, D.C. Standing upon a large platform, the new President takes the oath of office with one hand placed on a Bible.
Here are the words of the President’s oath of office:
I 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.
