The “Lame Duck Amendment” is more formally known as the 20th Amendment. Ratified in 1933, it moved up inauguration from March 4th — a month originally chosen to provide time for the newly-elected president to travel to the capital– to January 20th to limit the time that an outgoing president would be in office as a ‘lame duck’ prior to the end of his term. The last inauguration held in March was for Franklin D. Roosevelt in 1933.
