What Time Is The Inauguration 2013?

President Barack Obama's second term has already officially begun, as a quiet swearing-in ceremony was held on Sunday.

That oath took place at 11:55 a.m. because of a Constitutional requirement that the president begins his second term by noon on Jan. 20.

Now it's time for a more formal celebration and the vice presidential oath of office in Washington, D.C. The vice presidential oath is set for 11:46 a.m. Eastern Time on Monday, and it will be followed by the presidential oath at 11:55 a.m.
