President Donald Trump's Inauguration Day began with a church service, tea with Joe and Jill Biden and a ride over to the Capitol.
Trump quickly got to work by signing a series of executive orders after officially taking office as the nation's 47th president.
But that was just part of the day.
Inauguration celebrations will go through the evening and conclude with a night of inaugural balls. Here's everything you need to know about the festivities:
How long have inaugural balls been around?
According to the White House Historical Association, three features characterize nearly every presidential inauguration: the oath of office taken by the president at the Capitol, the inaugural parade and the inaugural ball.
The first inaugural ball took place in 1809 -- when an organization of young men called the Washington Dancing Assembly held a celebration to mark the inauguration of President James Madison.

How many inaugural balls are there?
Three inaugural balls -- each with a distinct purpose -- are planned for the 2025 inauguration, and all will be held at the Washington Convention Center. Trump is slated to give remarks at each event.
