The end of one presidential term and the start of another in the United States is signified by the inauguration of the new president. This ceremony occurs on January 20 following the presidential election, where the elected president takes the oath of office, officially commencing their term. The inauguration symbolizes the peaceful transfer of power, a cornerstone of American democracy. Events surrounding the inauguration often reflect national unity and celebration, although they can also be moments of political tension, especially following contentious elections.
