The first President to be sworn in on January 20th was Franklin Delano Roosevelt, as he was sworn in for his second of four terms in 1937. Dwight Eisenhower took the oath for his second term in 1957, on Sunday and was formally inaugurated again in public on Monday January 21. Ronald Reagan followed the same scenario in 1985 after winning re-election. January 20 falls on a Sunday four times in the Twenty-first Century; 2013, 2041, 2069, and 2097. It always occurs every 28 years.

As January 20, 1957 fell on a Sunday, President Eisenhower took the oath of office in a private White House ceremony. On Monday, January 21, 1957, he repeated the oath at the inaugural ceremonies held on the east portico of the White House. The oath was administered by Chief justice Earl Warren.

In the afternoon 750,000 spectators watched a three and one half hour parade over a three-mile route. Marching in the parade were 17,000 people, including 11,757 in military service.
