If January 20 falls on a Sunday, the president will be sworn in that day by taking the oath privately, but will then re-take the oath in a public ceremony the next day, on January 21. Nine vice presidents have succeeded to the presidency upon the death or resignation of the president. In these situations the oath of office was administered to the new president as quickly as possible, as doing so allowed the presidency to continue uninterrupted.

Option of affirmation

The Constitutional language gives the option to "affirm" instead of "swear." While the reasons for this are not documented, it may relate to certain Christians, including

is the only president known to have used the word "affirm" rather than "swear." Herbert Hoover is often listed to have used "affirm" as well, owing to his being a Quaker, but a newsreel taken of the ceremony indicates that the words used were "solemnly swear." Richard Nixon, who was also a Quaker, swore, rather than affirmed.


Forms

There have been two forms of administering, and taking, the oath of office. Under the first form, now in disuse, the administrator articulated the constitutional oath in the form of a question, and modifying the wording from the first to the second person, as in, "Do you, George Washington, solemnly swear ..." and then requested an affirmation. At that point a response of "I do" or "I swear" completed the oath. It is believed that this was the common procedure at least until the early 20th century. In 1881, the ''New York Times'' article covering the swearing in of Chester A. Arthur, reported that he responded to the question of accepting the oath with the words, "I will, so help me God." In 1929, ''Time'' magazine reported that the Chief Justice William H. Taft began the oath uttering, "You, Herbert Hoover, do you solemnly swear ...", Hoover replied with a simple "I do." Under the second, and current form, the administrator articulates the oath in the affirmative, and in the first person, so that the president takes the oath by repeating it verbatim. Franklin Roosevelt, in 1933, stood silent as Chief Justice Charles Evans Hughes recited the entire oath, then repeated that oath from beginning to end himself. By the time of Harry Truman's inauguration in 1949, the practice was for the chief justice to utter the oath in phrases, with the president repeating those phrases, until the oath was completed.

"So help me God"

The First Congress explicitly prescribed the phrase "So help me God" in oaths under the Judiciary Act of 1789 for all U.S. judges and officers other than the president. It was prescribed even earlier under the various first state constitutions as well as by the Second Continental Congress in 1776. Although the phrase is mandatory in these oaths, the said Act also allows for the option that the phrase be omitted by the officer, in which case it would be called an ''affirmation'' instead of an ''oath'': "Which words, so help me God, shall be omitted in all cases where an affirmation is admitted instead of an oath." In contrast, the oath of the president is the only oath specified in the Constitution. It does not include the closing phrase "So help me God," and it also allows for the optional form of an ''affirmation'' which is not considered an oath. In practice, most presidents, at least during the last century, have opted to take the ''oath'' (rather than an ''affirmation''), to use a Bible to do so, and also to close the oath with the customary phrase. There is currently debate as to whether or not

, the first president, added the phrase to his acceptance of the oath. The earliest known source indicating Washington added "So help me God" to his acceptance, not to the oath, is attributed to Washington Irving, aged six at the time of the inauguration, and first appears 65 years after the event. The only contemporary account that repeats the oath in full, a report from the French consul, Comte de Moustier, states only the constitutional oath, without reference to Washington's adding "So help me God" to his acceptance. The historical debate over who first used "So help me God" is marred by ignoring the two forms of giving the oath. The first, now in disuse, is when the administrator articulates the constitutional oath in the form of a question, as in, "Do you George Washington solemnly swear ...", requesting an affirmation. At that point a response of "I do" or "I swear" completes the oath. Without verbatim transcripts, the scant existing evidence shows this was the common procedure at least until the early 20th century. In 1865 the Sacramento ''Daily Union'' covered the second inauguration of Abraham Lincoln. Lincoln finished his oath with "So help me God," and he kissed the Bible. The ''Daily Union'' account is embellished in several ways, and other newspaper accounts published nearer to the ceremony do not mention the phrase (but they do not quote the oath in any form). In 1881, the ''New York Times'' article covering the swearing in of Chester A. Arthur reported that he responded to the question of accepting the oath with the words, "I will, so help me God." In 1929, ''Time'' magazine reported that the chief justice began the oath uttering, "You, Herbert Hoover, do you solemnly swear ..." Hoover replied with a simple "I do." A contemporaneous newspaper account of Lincoln's 1865 inauguration states that Lincoln appended the phrase "So help me God" to the oath. This newspaper report is followed by another account, provided later in the same year after Lincoln's death (April 15, 1865), that Lincoln said "So help me God" during his oath. The evidence pertaining to the 1865 inauguration is much stronger than that pertaining to Lincoln's 1861 use of the phrase. Several sources claim that Lincoln said "So help me God" at his 1861 inauguration, yet these sources were not contemporaneous to the event. During the speech, Lincoln stated that his oath was "registered in Heaven," something some have taken as indicating he likely uttered the phrase "So help me God." Conversely, there was a claim made by A. M. Milligan (a Presbyterian minister who advocated for an official Christian U.S. government) that letters were sent to Abraham Lincoln asking him to swear to God during his inaugurations, and Lincoln allegedly wrote back saying that God's name was not in the Constitution, and he could not depart from the letter of that instrument. Richard Gardiner's research published in the ''White House History Quarterly'', November 2024, offers contemporary evidence for presidents who used the phrase going back to William Henry Harrison in 1841, and Andrew Jackson. All federal judges and executive officers were required as early as 1789 by statute to include the phrase unless they affirmed, in which case the phrase must be omitted.

Taft eventually acknowledged his error, but did not think it was important, and Hoover did not retake the oath. In Taft's view, his departure from the text did not invalidate the oath. * In 1945, President Harry S. Truman's bare initial caused an unusual slip when he first became president and took the oath. At a meeting in the Cabinet Room, Chief Justice Harlan Stone, apparently mistaken about the meaning of Truman's middle initial (which is not an abbreviation but rather the whole middle name in itself), began reading the oath by saying "Do you, Harry Shipp Truman, ..."

This numerical discrepancy results chiefly from two factors: a president must take the oath at the beginning of each term of office, and, because Inauguration Day has sometimes fallen on a Sunday, five presidents have taken the oath privately before the public inauguration ceremony. In addition, three have repeated the oath as a precaution against potential later constitutional challenges.
