Donald Trump will take the oath of office as the 47th President of the United States at 12:00 PM on January 20, 2025, Eastern Standard Time (EST). Due to the time zone difference, this corresponds to 0:00 (midnight) on January 21, 2025, Vietnam time (GMT+7).

The inauguration will take place at the U.S. Capitol building in Washington, D.C. Due to forecasts of freezing weather with temperatures around -6 degrees Celsius, the ceremony is expected to be held inside the Capitol Rotunda instead of outdoors, marking the first time in 40 years that the inauguration of a U.S. president is held indoors.

After taking the oath, President Donald Trump will deliver an inaugural speech, expected to focus on a message of national unity, contrasting with the warning tone of his first inauguration in 2017.

The ceremony will be attended by many international leaders and executives from leading technology companies. This is the first time since 1874 that foreign leaders have been invited to the inauguration ceremony of the U.S. president.

After the oath ceremony, there will be a parade from the Capitol building to the White House, featuring military units, bands, and various groups, marking the beginning of Donald Trump's new presidential term.
