John F. Kennedy, often referred to as JFK, served as the 35th President of the United States. He was inaugurated on January 20, 1961, and his presidency was tragically cut short when he was assassinated on November 22, 1963.
To calculate the total number of days he was in office, we consider the period from his inauguration until his death. From January 20, 1961, to November 22, 1963, JFK served a total of 1,036 days as president.
This period included significant events such as the Cuban Missile Crisis and the establishment of the Peace Corps, making his presidency one of the most notable in American history, despite its brevity.
