President Joe Biden explained a National Day of Mourning in honor of the humanitarian leader on January 9, the day of Jimmy Carter’s funeral in Washington, DC

Although a national day of mourning is not recognized as an official federal holiday and many of the businesses normally affected by national celebrations are not closed, some organizations are affected by the day of remembrance.

Here’s what’s open and what’s closed on National Day of Mourning.

Is there mail?

Mail will not be delivered on Thursday. In an executive order issued on December 30, Biden declared that all federal agencies, including the United States Postal Service, would be closed in honor of Carter’s funeral on January 9.

All federal employees should have the day off, except for those most critical to the country’s “national security, defense or other public needs,” the announcement said.

The ruling also applies to all US courts, including the Supreme Court.

Are banks closed?

Most banks will remain open on Thursday because it is not an official federal holiday.

Is the stock exchange open?

In a statement released on December 30, Lynn Martin, president of the New York Stock Exchange Group, announced that all markets would be closed on January 9 out of respect for President Carter.

“Jimmy Carter, who came from humble roots as a farmer and family man, dedicated his life to public service and defending our freedom,” Martin wrote in the statement. “During his remarkable post-presidency life, President Carter left a lasting legacy of humanity.”

Are schools open?

Similar to most banks across the country, most public schools will remain open on Thursday because it is not an official federal holiday.

However, in accordance with the National Day of Mourning Protocol, all organizations associated with the educational activity of the US Department of Defense, including all military schools, will be closed.
