The federal government and large portions of the country’s financial sector will be closed on Wednesday for a day of mourning following the death of George H.W. Bush. It will be the first day of mourning for a former president since 2007 following Gerald Ford’s death. Though most federal employees will get the day off, essential services will still be open.

Here’s a list of closures for Bush’s funeral:

Employees deemed essential for national security and other vital government services will still have to report for work on Wednesday.

Some package services will still be running, but all other mail delivery will be postponed and post offices will be closed.

The House of Representatives will postpone votes for the week after Bush’s death. The Senate will postpone until after Wednesday’s funeral.

The Board of Governors’ offices in Washington will be closed on Wednesday, but Federal Reserve Bank payment systems will still operate normally.

The nation’s highest court will postpone arguments on Gamble v. United States, a case it is currently hearing, until Thursday.

Not all chief judges will close their courthouses for the day of mourning. The U.S. District Court for the District of Columbia will be closed, but the District Court for the Southern District of Indiana will operate on a “modified basis” with limited staff in some offices, according to its website. The District Court for Oregon will be open for business on Wednesday.

The New York Stock Exchange and Nasdaq will be closed on a nonholiday for the first time since Hurricane Sandy in 2012. The NYSE, Nasdaq and CME held a minute of silence in honor of Bush on Monday.

Bond markets will be closed on the recommendation of the Securities Industry and Financial Markets Association, the trade organization for securities firms and banks. Many private banks, however, will remain open.
