Donald Trump is set to be sworn in today as the 47th President of the United States. At 78 years old, he will begin his second term, setting a new record as the oldest individual to assume the presidency. He will surpass his predecessor, Joe Biden, by five months, who previously held the record as the oldest president on Inauguration Day in 2021.

The Oldest and Youngest Presidents

According to Statista, the youngest U.S. president at the time of inauguration was Theodore Roosevelt, who assumed the presidency at the age of 42 following the assassination of William McKinley in 1901. In contrast, the current president now holds the record for being the oldest at the time of inauguration, as mentioned earlier.

Who Lived the Longest?

The longest-living U.S. president was Jimmy Carter, who passed away on December 29, 2024, at the age of 100. He was born on October 1, 1924. On the other hand, John F. Kennedy had the shortest lifespan of any U.S. president. He was assassinated in 1963 at the age of 46.

Presidential Terms: Longest and Shortest

Before 1951, there was no formal limit on the number of terms a U.S. president could serve. The two-term limit was established by the 22nd Amendment, ratified on February 27, 1951, largely in response to Franklin Roosevelt’s four terms in office. Roosevelt served from 1933 to 1945, completing more than 12 years in office before passing away at the age of 63 during his fourth term.

The shortest-serving president was William Harrison, who died on April 4, 1841, just one month after his inauguration on March 4 of the same year.
