This order will lead to federal agencies closing and employees being excused from work this year, creating a three-day break inclusive of Christmas Day.
The decision follows Trump's earlier criticism of Juneteenth, a federal holiday, where he stated there were "too many non-working holidays" costing the country billions.
With these additions, the US will have 13 federal holidays this year; Trump previously designated Christmas Eve as a holiday in 2019 and 2020.
Separately, the National Park Service announced free admission on Trump's birthday and other federal holidays in 2026, but excluded Martin Luther King Jr. Day and Juneteenth.
