- The longest inaugural address was delivered by William Henry Harrison -- after delivering the 8,445-word address on a cold day in March 1841, he died a month later of pneumonia.
- This is the seventh time in U.S. history the official presidential inauguration date has fallen on a Sunday. Each time, this pushed the public ceremony into Monday.
- Inaugurations weren't always staged for the public. The inaugurations for George Washington's second term and for John Adams were held in Philadelphia -- inside Congress Hall. Thomas Jefferson then moved the ceremony back to D.C. in 1801, while still taking the oath inside the Senate. James Monroe moved the ceremony back to a public affair in 1817.
- The words "so help me God" are not technically part of the constitutionally prescribed oath of office. Washington started the practice at the end of his 1789 ceremony.
- The chief justice of the Supreme Court usually administers the oath. But when Washington was sworn in in 1789, no justice had yet been appointed. So Robert R. Livingston, chancellor of New York state, administered.
- Most, but not all, of the oath ceremonies have included a Bible. Washington started the practice by using a Bible from a nearby Masonic Lodge.
- Warren G. Harding was the first to deliver his address using speakers, Calvin Coolidge the first to have his address broadcast by radio and Harry Truman the first to deliver his address over television.
