What is the duration of one term for a U.S. president?

The duration of one term for a U.S. president is four years. This standard is established by the Constitution, specifically in Article II, which outlines the executive branch of the government. Each president is elected to serve for four years, and they can be re-elected for one additional term, making a maximum of eight years in total if they are successful in both elections. The four-year term allows for a balance between providing enough time for the president to implement policies and initiatives while also ensuring they remain accountable to the electorate through regular elections. This systematic approach is vital for maintaining democratic processes and responsiveness in leadership.
