when did trump take office

Donald Trump has taken office as U.S. president on two separate Inauguration Days: January 20, 2017, and January 20, 2025. He is currently serving his second term, having been inaugurated again in 2025.

First time Trump took office

• Trump first took office as the 45th president of the United States on January 20, 2017.

• The swearing-in ceremony took place at the U.S. Capitol in Washington, D.C., marking the start of his first presidential term.

Second time Trump took office

• After being reelected in November 2024, Trump was inaugurated again on January 20, 2025, as the 47th president.

• This 2025 ceremony marked the beginning of his second and final term, with JD Vance sworn in as vice president.

Why those exact dates?

• U.S. law and the Constitution fix presidential Inauguration Day to January 20 every four years, except when it falls on a Sunday.

• That is why both of Trump’s inaugurations—and thus the moments he formally “took office”—fell on January 20 in 2017 and 2025.
