Donald Trump is the 45th President of the United States of America. However, only 44 men have served as president. This is because presidents are numbered by their continuous terms in office. Grover Cleveland, who won two non-consecutive terms in 1884 and 1892, is therefore the 22nd and 24th president. Presidents are elected in November every four years and sworn into office on January 20 the following year. Until 1936, inaugurations took place on March 4. The table below shows presidential terms by the years served. Full text, video and audio of Donald Trumpâs Inaugural Address as the 45th President.
