President Joe Biden appointed Jan. 9, as a day of mourning for Jimmy Carter for people to 'pay homage to the memory' of the former president.

To honor Carter, a Nobel Peace Prize recipient who resided in Massachusetts in the 1950s, all federal offices will be closed on Jan. 9 in observance of the day of mourning. While various other organizations may choose to also close in honor of Carter, unlike on a federal holiday, businesses are not required to close.
