According to the 20th Amendment, when does a president's term end?

The 20th Amendment to the United States Constitution clearly establishes that the term of a president ends at noon on January 20th following the presidential election. This amendment was ratified in 1933 to address the issues associated with the time delay between Election Day and the inauguration of a new president, which previously occurred on March 4th. By specifying January 20th as the end date for a presidential term, the amendment ensures a smoother transition of power and minimizes the period during which a president serves without being elected by the people.

The significance of this provision lies in its contribution to the efficiency and clarity of the presidential succession process. It delineates the exact moment when a new president assumes office and a former president's term concludes, providing a clear timeline that helps prevent any ambiguity regarding presidential authority.
