President Barack Obama will kick off his inaugural festivities with a national day of service on Jan. 19.

The Presidential Inaugural Committee is also announcing that the four living past presidents will serve as honorary co-chairs: Jimmy Carter, George H.W. Bush, Bill Clinton and George W. Bush.

A slew of other Obama campaign officials and supporters of the president are also joining the inaugural committee, including actress Eva Longoria. She has been named a committee co-chair.

Obama will take the oath of office in a private ceremony on Jan. 20, a Sunday. The public swearing-in, along with a parade and several inaugural balls, will take place the next day.
