List of Presidents of the United States by time in office
William Henry Harrison
This is a list of Presidents of the United States by time in office. The basis of the list is the difference between dates; if counted by number of calendar days all the figures would be one greater, with the exception of Grover Cleveland, who would receive two days.
Since 1789, there have been 44 people sworn into office as President of the United States, and 45 presidencies, as Grover Cleveland served two non-consecutive terms and is counted chronologically as both the 22nd and 24th president. Of the individuals elected president, four (William Henry Harrison, Zachary Taylor, Warren G. Harding, and Franklin D. Roosevelt) died of natural causes while in office, four (Abraham Lincoln, James A. Garfield, William McKinley, and John F. Kennedy) were assassinated, and one (Richard Nixon) resigned.
William Henry Harrison spent the shortest time in office, and Franklin D. Roosevelt spent the longest. He is the only president to have served more than two terms. Presidents since Dwight D. Eisenhower have been constitutionally limited to two terms under the 22nd Amendment.

- The 20th Amendment (ratified in 1933) moved Inauguration Day from March 4 to January 20. The 1937 presidential inauguration was the first to take place on the new date. As a result, Franklin Roosevelt's first term in office (1933–1937) was only 1,418 days long, 1 month and 12 days shorter than a normal term.
- Of years evenly divisible by 100, only those evenly divisible by 400 are leap years. The years 1800 and 1900 are divisible by 100, but not by 400. Thus, John Adams's term and McKinley's first term did not include a 366-day leap year, so those terms were one day shorter than a normal full term. The year 2000 is divisible by 400 and so did include one, thus Clinton's second term was not shorter than his first.
- Due to logistical delays, Washington's first inauguration was held 1 month and 26 days after the scheduled start of operations of the new government under the Constitution of the United States. As a result, his first term was only 1,404 days long, and was the shortest term for a U.S. president who neither died in office nor resigned.
- The 22nd Amendment (ratified in 1951) made a president ineligible for election to a third term or for election to a second full term after serving more than two remaining years of a term of a previously elected president. The latter clause would have applied to Truman's situation in 1952 except that a grandfather clause in the amendment explicitly excluded the amendment from applying to the incumbent president.
