Inauguration Day in the United States occurs every four years on January 20. If January 20 falls on a Sunday, the ceremony is held privately that day and publicly on the following Monday, January 21. The inauguration marks the day when the president-elect and vice-president-elect are sworn into office, officially beginning the new presidential term. The ceremony is traditionally held at the U.S. Capitol in Washington, D.C. The next scheduled presidential inauguration day is January 20, 2029. The most recent inauguration was on January 20, 2025, when Donald Trump was sworn in for his second term.
