Because it's a federal and state holiday, mostly all government offices are closed, as are banks, libraries and businesses.
Memorial Day is a federal holiday observed every year on the last Monday in May.
It honors those who died serving the U.S. military. It is traditional to fly the American flag at half-staff until noon and then raise it until sundown.
Memorial Day originated after the Civil War to honor both the Union and Confederate soldiers who died in the war. The holiday was later extended to include all American soldiers.
In addition to federal offices, state and local government offices are closed, and there will be no mail delivery.
Here's a rundown of what else is closed.
Liquor stores: In Pennsylvania, liquor stores are state-run and are closed. New Jersey liquor stores are privately owned and hours vary by location.
