President Donald Trump gave an executive order on December 17 to close all “executive departments and agencies of the federal government” on Tuesday, December 24, 2019, according to the White House. This means that employees working for the government should have an extra day off before Christmas.

The decision whether employees “report for duty” on Christmas Eve is at the discretion of the heads of the executive departments and agencies, according to the executive order. Some organizations, or part of them, might remain open due to reasons of “national security, defense or other public need” the order says.

Which government offices will be closed on Christmas Eve?

According to the government website, the following offices, departments and agencies fall under the executive departments of the Federal Government.
