Washington (CNN)Inauguration Day, even in the age of Donald Trump, is still pretty predictable, thanks to a city known for tradition and pomp and circumstance.

Here’s a rundown and a bit of history of all the people, places and things that will be a part of the action on January 20.

Every president-elect since Jimmy Carter has stayed at Blair House, the guest home that sits across the street from the White House.

The church has even set aside a special pew — No. 54 — for the President and his guests. According to the church, every President since James Madison has attended a service at St. John’s during his lifetime.

This part of the day takes place at the US Capitol. Perhaps you’ve heard of it. The 20th Amendment stipulates that the “terms of the President and Vice President shall end at noon on the 20th day of January,” which saves the government the trouble of having to figure out a time that works for everyone. Even if January 20 falls on a weekend, the new president must be sworn in that day. It happened to President Barack Obama in 2013, when he had to do a swearing-in at the White House on a Sunday and the ceremony the following Monday.
