context_page_description: The inauguration of the president of the United States is a ceremony to mark the commencement of a new four-year term of the president of the United States. This ceremony takes place for each new presidential term, even if the president is continuing in office for a second term. Since 1937, it has taken place at noon EST on January 20, the first day of the new term, some 72 to 78 days after the presidential election, except for three occasions when January 20 fell on a Sunday. In those years, the presidential oath of office was administered on that day privately and then again in a public ceremony the next day, on Monday, January 21. The most recent presidential inauguration ceremony was held on January 20, 2017, when Donald Trump officially assumed office. The next inauguration is scheduled take place on Wednesday, January 20, 2021.
  Recitation of the presidential oath of office is the only component in this ceremony mandated by the United States Constitution. Though it is not a constitutional requirement, the chief justice typically administers the presidential oath of office.
context_section_description: The security for the inaugural celebrations is a complex matter, involving the Secret Service, Department of Homeland Security, Federal Protective Service (DHS-FPS), all five branches of the Armed Forces, the Capitol Police, the United States Park Police (USPP), and the Metropolitan Police Department of the District of Columbia (MPDC). Federal law enforcement agencies also sometimes request assistance from various other state and local law-enforcement agencies throughout the United States.
