All U.S. Postal Service offices will be closed today, Jan. 9, to honor Jimmy Carter. The closure is part of an observance following the passing of the 39th president, who died on Dec. 29, 2024, at the age of 100.

The decision, announced last week, came after President Joe Biden announced a National Day of Mourning and a one-day closure of federal agencies and departments. Jan. 9 is designated as a national day of reflection on Carter’s contributions to public service, peace and humanitarian efforts.

“All executive departments and agencies of the federal government shall be closed on January 9, 2025, as a mark of respect for James Earl Carter Jr., the thirty-ninth President of the United States,” Biden wrote in the executive order.

President Donald Trump declared a similar day of mourning following President George H.W. Bush’s death in 2018, when post offices were also closed.
