The first hundred days of a United States President first term are sometimes used to measure a president's success and achievements when their power and influence are at its highest.[1] The term was coined in a July 24, 1933 radio address by U.S. President Franklin D. Roosevelt. However, he referred to the 100-day session of the 73rd United States Congress from March 9 to June 17, rather than the first 100 days of his administration.[2]
