Donald Trump's presidential inauguration is scheduled to begin at noon ET. According to the U.S. Constitution's 20th Amendment, each presidential inauguration should take place Jan. 20, unless that date falls on a Sunday. Then, the president takes the oath of office in private Jan. 20, and the public event is moved to Jan. 21.

Trump’s second inauguration, the 60th U.S. presidential inauguration, will be held on Monday, Jan. 20, on the western side of the U.S. Capitol Building.
