Longest presidency | Shortest presidency |
The length of a full four-year term of office for a president of the United States usually amounts to 1,461 days (three common years of 365 days plus one leap year of 366 days). The listed number of days is calculated as the difference between dates, which counts the number of calendar days except the first day (day zero). If the first day were included, all numbers would be one day more, except Grover Cleveland would have two more days, as he served two non-consecutive terms. [a]
Of the individuals elected president of the United States, four died of natural causes while in office (William Henry Harrison, [1] Zachary Taylor, [2] Warren G. Harding [3] and Franklin D. Roosevelt), four were assassinated (Abraham Lincoln, [4] James A. Garfield, [4] [5] William McKinley [6] and John F. Kennedy) and one resigned from office (Richard Nixon). [7]
William Henry Harrison spent the shortest time in office, while Franklin D. Roosevelt spent the longest. Roosevelt is the only American president to have served more than two terms. Following ratification of the Twenty-second Amendment in 1951, presidents—beginning with Dwight D. Eisenhower—have been ineligible for election to a third term or, after serving more than two years of a term to which some other person was elected president, to a second term. The amendment contained a grandfather clause that explicitly exempted the incumbent president, then Harry S. Truman, from the new term limitation.
Grover Cleveland and Donald Trump were voted out of office after one term, but they were later elected to a second non-consecutive term. Consequently, while there have been 47 presidencies in the nation's history, only 45 people have been sworn into office.

William McKinley was the 25th president of the United States, serving from 1897 until his assassination in 1901. A member of the Republican Party, he led a realignment that made Republicans largely dominant in the industrial states and nationwide for decades. McKinley oversaw a period of American expansionism, including the annexations of Puerto Rico, Guam, the Philippines, and Hawaii. He led the U.S. into the Spanish–American War and put down a pro-independence rebellion in the Philippine–American War. McKinley also rejected inflationary plans such as free silver in favor of keeping the nation on the gold standard, and raised protective tariffs.
Presidential elections were held in the United States on November 5, 1872. Incumbent President Ulysses S. Grant, the Republican nominee, easily defeated Democratic-endorsed Liberal Republican nominee Horace Greeley.
Presidential elections were held in the United States on November 8, 1892. In the fourth rematch in American history, the Democratic nominee, former president Grover Cleveland, defeated the incumbent Republican President Benjamin Harrison. Cleveland's victory made him the first president in American history to be elected to a non-consecutive second term, a feat not repeated until Donald Trump was elected in 2024. The 1892 election saw the incumbent White House party defeated in three consecutive elections, which did not occur again until 2024.
The Twenty-second Amendment to the United States Constitution limits the number of times a person can be elected to the office of President of the United States to two terms, and sets additional eligibility conditions for presidents who succeed to the unexpired terms of their predecessors. Congress approved the Twenty-second Amendment on March 21, 1947, and submitted it to the state legislatures for ratification. That process was completed on February 27, 1951, when the requisite 36 of the 48 states had ratified the amendment, and its provisions came into force on that date.
Charles Warren Fairbanks was an American politician who served as the 26th vice president of the United States under President Theodore Roosevelt from 1905 to 1909. A member of the Republican Party, Fairbanks was previously a senator from Indiana from 1897 to 1905.
Marcus Alonzo Hanna was an American businessman and Republican politician who served as a United States Senator from Ohio as well as chairman of the Republican National Committee.

The 1960 United States Senate elections coincided with the election of John F. Kennedy as president on November 8, 1960. The 33 seats of Class 2 were contested in regular elections. A special election was also held on June 28, 1960, for a mid-term vacancy in North Dakota where Democrats flipped a seat to expand their majority to 66–34. As Majority Leader Lyndon Johnson was elected Vice President, Mike Mansfield became the new majority leader.
The 1914 United States Senate elections were held on November 3, 1914. These were the first regularly scheduled elections held following the ratification of the Seventeenth Amendment to the United States Constitution in 1913, which required that all seats up for election be popularly elected, rather than chosen by their state legislatures. Thus, it was the first time that elections were generally scheduled on Election Day to coincide with the U.S. House elections. The 32 seats of Class 3 were contested in regular elections in 1914. Special elections were also held to fill vacancies. These elections occurred in the middle of Democratic President Woodrow Wilson's first term.
The Curse of Tippecanoe is an urban legend about the deaths in office of presidents of the United States who were elected in years divisible by 20. According to the legend, Tenskwatawa, leader of Native American tribes defeated in 1811 at the Battle of Tippecanoe by a military expedition led by William Henry Harrison, had cursed the "Great White Fathers".
A death in office is the death of a person who was incumbent of an office-position until the time of death. Such deaths have been usually due to natural causes, but they are also caused by accidents, suicides, disease and assassinations.
Grover Cleveland was president of the United States first from March 4, 1885, to March 4, 1889, and then from March 4, 1893, to March 4, 1897. The first Democrat elected after the Civil War, Cleveland was the first U.S. president to leave office after one term and later be elected for a second term, and the only one to date to have served two full non-consecutive terms. His presidencies were the nation's 22nd and 24th. Cleveland defeated James G. Blaine of Maine in 1884, lost to Benjamin Harrison of Indiana in 1888, and then defeated President Harrison in 1892. He was succeeded by Republican William McKinley, who won in 1896.
