paragraph_text: Inauguration
  
  Pursuant to the Twentieth Amendment, the four-year term of office for both the president and the vice president begins at noon on January 20, in the year following the preceding presidential election. The first presidential and vice presidential terms to begin on this date, known as Inauguration Day, were the second terms of President Franklin D. Roosevelt and Vice President John Nance Garner in 1937. Previously, Inauguration Day was on March 4. As a result of the date change, the first term (1933–37) of both men had been shortened by 43 days.
  
  Before executing the powers of the office, a president is required to recite the presidential Oath of Office, found in Article II, Section 1, Clause 8 of the Constitution. This is the only component in the inauguration ceremony mandated by the Constitution:
  
  I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect, and defend the Constitution of the United States.
  
  Presidents have traditionally placed one hand upon a Bible while taking the oath, and have added "So help me God" to the end of the oath. Although the oath may be administered by any person authorized by law to administer oaths, presidents are traditionally sworn in by the chief justice of the United States.
