In what month is the President inaugurated?

The President of the United States is inaugurated in January. This tradition is rooted in the 20th Amendment to the U.S. Constitution, which was ratified in 1933. The amendment established that the President's term begins on January 20th following the election, which occurs in November. This change was made to reduce the lengthy interval between the election and the inauguration that had existed previously. The January inauguration allows for a smoother transition of power and sets the stage for the new administration to begin its work promptly. Other months listed do not correspond to the inauguration date and do not hold any significance in this context regarding the official commencement of a President's term.
