President Jimmy Carter's funeral is Jan. 9, which was declared a national day of mourning. The stock market and post office will be impacted.

On Dec. 30, Biden ordered that “all executive departments and agencies of the Federal Government shall be closed on Jan. 9,” except those necessary for “national security, defense, or other public need.” Federal employees will still be paid for the day.

On Dec. 29, California Gov. Gavin Newsom also announced that flags at the State Capitol and Capitol Annex Swing Space would be flown at half-staff in honor of Carter. The country’s most recent national day of mourning was in December 2018, following the death of former President George H.W. Bush.
