Memorial Day weekend runs from Friday through Monday, giving American workers some much-needed time off as they honor fallen soldiers who died protecting the country. Because many businesses and government offices shut down for the national holiday, you'll need to buy your barbecue supplies and mail out your bills a little bit early.

To help you plan your weekend accordingly, we've compiled a list of what's open and closed this weekend in the United States:

Post offices won't be open or delivering mail Monday, and neither will UPS. Remember that neither service delivers on Sundays, either. Fed Ex will shut down Monday, as well.

Federal offices like Social Security will be closed Monday, and so will many state motor vehicles locations. Most schools have the day off as well. Hospitals will remain open, but depending on where you are, they could have reduced staffing. Local libraries' hours vary, but note that the New York Public Library will be closed all weekend.

Federal Reserve banks and branches will be closed Monday. Bank of America offices and financial centers will shut down Monday, as well, so transactions may take longer to process. Wells Fargo's bond market will close at 2 p.m. EDT on Friday, and all trading will be unavailable Monday. Chase Bank, HSBC, TD Bank and others will also be closed Monday so staff members can be with their friends and relatives.

Transit policies for Memorial Day vary by location. In New York City, the MTA will have its subways and buses operating on a Sunday schedule, which includes no 5 service in Brooklyn, no B or Z service and limited Q and M service. In Washington, D.C., the Metrobus and Metrorail systems will run on a Sunday schedule, which includes no Orange Line service and limited Silver and Blue Line service. In the San Francisco Bay Area, the BART will run on a Sunday schedule except between San Leandro and Bay Fair, where the tracks will be closed.

Many stores, especially those running sales, will be open on Memorial Day. Macy's, Walmart and Target will have their normal hours, according to

As always, call ahead to confirm the hours for any institution. Have a safe weekend.
