(NECN/NBC News: Tracie Potts, Washington) - Four years after making history, Sunday morning President Obama will take the oath of office again in a small ceremony at the White House.
The president has been talking about what this day means online with the inaugural committee.
"The inauguration reminds us of the role we have as fellow citizens in promoting a common good," said Obama.
He also talked about the inauguration to children at a Washington school where the first family picked up paint brushes as part of Saturday's National Day of Service.
"It's a symbol of how our democracy works and how we peacefully transfer power. It should also be an affirmation that we're all in this together," said Obama.
The Bidens packed care packages for soldiers Saturday. His swearing in will be early Sunday morning at the Naval Observatory.
The big public ceremony will be Monday at the U.S. Capitol.
Washington's expecting more than half a million people.
"We're excited that as many Americans as possible will be a part of this," said Brent Colburn, Presidential Inaugural Committee.
It's expected to be a much smaller crowd than four years ago, but no less enthusiastic.
