For Obama, that difference is even sharper. His historic ascendancy to the White House in 2008 came with soaring public hopes and expectations for a new kind of governance that would close the vast partisan gulf developed in recent decades.
Obama had selected historical bibles including those used by Abraham Lincoln and Martin Luther King for his swearing in ceremonies.
"I will be honoured to again stand on the inaugural platform and take part in this important American tradition," Obama had said earlier this month.
US Presidents Dwight D Eisenhower and Ronald W Reagan also had two ceremonies, one private swearing-in on a Sunday and a public oath ceremony on the following Monday.
