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.

According to the 22nd Amendment, which was ratified in 1951, no President may serve more than two terms plus a maximum of two years having acceded as President under some other President's term (or more than one term following more than two years having acceded under some other President's term). This means it is likely that Franklin Delano Roosevelt will continue to be the first on this list unless the 22nd Amendment is changed or repealed and some future President is re-elected the requisite number of times pursuant to such a change or repeal.

  1. ^ His first term in office (1933–1937) was the shortest term for an elected President (after Washington’s) who neither died in office nor resigned. The Twentieth Amendment moved Inauguration Day from March 4 to January 20 beginning in 1937; therefore, Roosevelt's first term was 43 days (1 month and 13 days) short of a full four years: from March 4, 1933 through January 20, 1937, a period of 1,418 days.
  2. ^ Updated daily according to UTC.
  3. ^ The short period Nixon did serve in his second term makes Nixon the longest combined service as president and vice president with a total of 4,949 days (2,922 days as vice president), eclipsing Franklin D. Roosevelt by 527 days.
  4. ^ a b 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 all other full terms.
