The vice president is sworn into office in the same ceremony as the president. Prior to 1937, the [[Oath of office of the vice president of the United States|vice presidential oath]] was administered in the [[United States Senate|Senate Chamber]] (in keeping with the vice president's position as president of the Senate). The oath is administered to the vice president first. Immediately afterwards, the [[United States Marine Band]] will perform four "[[ruffles and flourishes]]", followed by "[[Hail, Columbia]]". Unlike the presidential oath, however, the Constitution does not specify specific words that must be spoken. Several variants of the oath have been used since 1789. The current form, which is also recited by senators, representatives, and other government officers, has been in use since 1884:

{{cquote|I do solemnly swear (or [[Affirmation in law|affirm]]) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.<ref>{{usc|5|3331}}</ref>
}}

At noon, the new presidential and vice presidential terms begin. At about that time, the president recites the constitutionally mandated oath of office:

{{cquote|I do solemnly swear (or [[Affirmation in law|affirm]]) 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.}}

According to [[Washington Irving]]'s biography of George Washington, after reciting the oath at his (and the nation's) first inauguration, Washington added the words "so help me God".<ref>{{cite web |url=http://2002-2009-fpc.state.gov/40871.htm |title=Presidential Inaugurations Past and Present: A Look at the History Behind the Pomp and Circumstance |publisher=2002-2009-fpc.state.gov |access-date=November 7, 2012 |archive-date=February 22, 2013 |archive-url=https://web.archive.org/web/20130222000457/http://2002-2009-fpc.state.gov/40871.htm |url-status=dead }}</ref> However, the only contemporaneous source that fully reproduced Washington's oath completely lacks the religious codicil.<ref>''Documentary History of the First Federal Congress'', Vol. 15, pages 404–405</ref> The first newspaper report that actually described the exact words used in an oath of office, Chester Arthur's in 1881,<ref>{{cite news

The oath of office was administered to Washington in 1789 by [[Robert R. Livingston (chancellor)|Robert Livingston]], Chancellor of New York State. Four years later, the oath was administered by [[Associate Justice of the United States Supreme Court|Supreme Court associate justice]] [[William Cushing]]. Since the 1797 inauguration of [[John Adams]], it has become customary for the new president to be sworn into office by the Supreme Court's [[Chief Justice of the United States|chief justice]]. Others have administered the oath on occasions when a new president assumed office intra-term due to the incumbent's death or resignation.  [[William Cranch]], chief judge of the U.S. Circuit Court, administered the oath of office to [[John Tyler]] in 1841 when he succeeded to the presidency upon [[William Henry Harrison]]'s death, and to [[Millard Fillmore]] in 1850 when [[Zachary Taylor]] died. In 1923, upon being informed of [[Warren Harding]]'s death, while visiting his [[Coolidge Homestead|family home]] in [[Plymouth Notch, Vermont]], [[Calvin Coolidge]] was sworn in as president by his father, [[John Calvin Coolidge, Sr.]], a [[notary public]].<ref>Glenn D.

Hughes]] administered the oath of office to [[Lyndon B. Johnson]] aboard [[Air Force One]] after [[John F. Kennedy assassination|John F. Kennedy's assassination]] on November 22, 1963.

Since 1789 there have been 59 inaugural ceremonies to mark the commencement of a new four-year term of a president of the United States, and an additional nine marking the start of a partial presidential term following the intra-term death or resignation of an incumbent president. With the [[Inauguration of Joe Biden|2021 inauguration]] of [[Joe Biden]], the oath has been taken 73 different times by 45 people. This numerical discrepancy results chiefly from two factors: a president must take the oath at the beginning of each term of office, and, because the day of inauguration has sometimes fallen on a Sunday, five presidents have taken the oath privately before the public inaugural ceremonies.<ref name="inaugUSCap">{{cite web|url=https://www.aoc.gov/nations-stage/inauguration-us-capitol|title=Inauguration at the U.S. Capitol|publisher=Architect of the Capitol|access-date=January 22, 2017}}</ref>

There is no requirement that any book, or in particular a book of sacred text, be used to administer the oath, and none is mentioned in the Constitution. By convention, incoming presidents raise their right hand and place the left on a [[Bible]] or other book while taking the oath of office. While most have, [[John Quincy Adams]] did not use a Bible when taking the oath in 1825;<ref>{{cite web|url=https://www.loc.gov/rr/program/bib/inaugurations/jqadams/index.html|title=U.S. Presidential Inaugurations: John Quincy Adams|work=Web guides|publisher=Library of Congress|access-date=January 29, 2017}}</ref> neither did [[Theodore Roosevelt]] in 1901.<ref>{{cite web|url=https://www.loc.gov/rr/program/bib/inaugurations/theodoreroosevelt/index.html|title=U.S. Presidential Inaugurations: Theodore Roosevelt|work=Web guides|publisher=Library of Congress|access-date=January 29, 2017}}</ref>  In 1853, [[Franklin Pierce]] affirmed the oath of office rather than swear it.<ref>{{cite web|url=https://guides.loc.gov/presidential-inaugurations/1829-1857#s-lg-box-wrapper-31051987|title=U.S. Presidential Inaugurations: Franklin Pierce|work=Web guides|publisher=Library of Congress|access-date=January 22, 2024}}</ref> More recently, a Catholic [[missal]] was used for Lyndon B.

Bibles of historical significance have sometimes been used at inaugurations. [[George H. W. Bush]], [[Jimmy Carter]] and [[Dwight D. Eisenhower]] used the [[George Washington Inaugural Bible]]. [[Barack Obama]] placed his hand upon the [[Lincoln Bible]] for his oaths in 2009 and 2013,<ref>{{cite web|url=http://www.pic2009.org/blog/entry/president-elect_barack_obama_to_be_sworn_in_using_lincolns_bible/|title=President-elect Barack Obama to be Sworn in Using Lincoln's Bible|publisher=Presidential Inaugural Committee|date=December 23, 2008|url-status=dead|archive-url=https://web.archive.org/web/20090119012923/http://pic2009.org/blog/entry/president-elect_barack_obama_to_be_sworn_in_using_lincolns_bible|archive-date=January 19, 2009}}</ref> as did Donald Trump in 2017.<ref>{{cite news |url=https://www.washingtonpost.com/news/morning-mix/wp/2017/01/18/the-symbolism-of-trumps-two-inaugural-bible-choices-from-lincoln-to-his-mother/ |title=The symbolism of Trump's two inaugural Bible choices, from Lincoln to his mother |newspaper=[[The Washington Post]] |first=Katie |last=Mettler |date=January 18, 2017 |access-date=January 29, 2017}}</ref> [[Joe Biden]] placed his hand upon a large leather-bound family Bible.<ref>{{cite web| last=Schumaker| first=Erin| date=January 20, 2021| title=The significance of the Bible Joe Biden is using on Inauguration Day| url=https://abcnews.go.com/Politics/significance-bible-joe-biden-inauguration-day/story?id=75369058| website=[[ABC News|abcnews.go.com]]| access-date=January 21, 2021}}</ref>

Immediately after the presidential oath, the [[United States Marine Band]] will perform four "ruffles and flourishes", followed by "[[Hail to the Chief]]", while simultaneously, a [[21-gun salute]] is fired using [[artillery|artillery pieces]] from the Presidential Guns Salute Battery, [[3rd United States Infantry Regiment (The Old Guard)|3rd United States Infantry Regiment "The Old Guard"]] located in Taft Park, north of the Capitol. The actual gun salute begins with the first "ruffle and flourish", and "run long" (i.e. the salute concludes after "Hail to the Chief" has ended). The Marine Band, which is believed to have made its inaugural debut in 1801 for Thomas Jefferson's first inauguration, is the only musical unit to participate in all three components of the presidential inauguration: the swearing-in ceremony, the inaugural parade, and an inaugural ball. During the ceremony, the band is positioned directly below the presidential podium at the U.S. Capitol.<ref name="thepresident'sown">{{cite web |url=http://www.marineband.marines.mil/Unit-Home/Presidential-Inauguration-2017/ |title=Presidential Inauguration 2017 |publisher=[[United States Marine Corps]] |access-date=January 27, 2017}}</ref>
