Happy Inauguration Day!
Inauguration Day is when the commencement of a new term of the President of the United States begins, following an oath. Franklin D. Roosevelt was the last president to be sworn in on March 4 in 1933, before the date of inauguration was changed to January 20. Every four years, the President is sworn in to office on January 20, except when that date falls on a Sunday.
If January 20 happens to be a Sunday, there will be a private swearing-in on the 20 and the public ceremony will be held on Monday, January 21. This dates back to President Monroe’s inauguration in 1821, where he decided to hold the ceremony on a Monday because most public offices were closed on Sundays.
Only 6 times in history has Inauguration Day fallen on a Sunday, and January 20, 2013 will be the seventh. Barack Obama will begin his second term as President and be sworn in by the Chief Justice in a private ceremony on Sunday, January 20 then a public ceremony the next day. January 21, 2013 will mark the 57th Presidential Inauguration.
