Five days after the death of the nation's 41st president, Americans will observe a day of mourning this Wednesday for George H.W. Bush.

The day, announced by President Donald Trump on Saturday, will honor the 94-year-old former president who died Friday night. The federal government will be closed on Wednesday, as will the New York Stock Exchange and Nasdaq. A state funeral will be held at the Washington National Cathedral that day, beginning at 11 a.m.

The agency said Monday that it will halt “regular mail deliveries, retail services and administrative office activity” on Dec. 5 as part of the National Day of Mourning.

The United States Postal Service will suspend its regular delivery operations.

“We will provide limited package delivery service on that day to ensure that our network remains fluid and we do not experience any impacts to our package delivery operations that might negatively affect our customers or business partners during the remainder of our busy holiday season,” the agency explained.

Trump has also ordered flags to be lowered to half-staff for 30 days.
