What's open and closed on Jan. 9, a national day of mourning for Jimmy Carter

Federal offices and select agencies will close Thursday, Jan. 9, after President Biden declared a national day of mourning to honor former President Jimmy Carter's death.

On Dec. 29, Biden called on federal agencies the next day to fly flags at half-staff for a month to pay tribute to Carter. In a statement, Biden said Carter's  life of service defined him as "one of the most influential statesmen in our history."

The last time the nation observed a national day of mourning was in December 2018, when then-President Trump declared it for the death of former president George H.W. Bush.
