When was Barack Obama reinaugurated?

Answer 1

His second inauguration was done twice-- once on January 20th, 2013 (the date specified in the constitution), and then a second time on January 21st. This time, the 20th fell on a Sunday, when government offices were closed, so the first oath of office occurred at a small, private ceremony in the White House. The next day, there was a large, public ceremony, and the oath was given on the steps of the Capitol Building.
