As people around the U.S. prepare to travel, host a cook-out, or just hang out this Memorial Day weekend, many will be planning their activities around when they can purchase the supplies needed for their festivities.

Memorial Day is a national holiday in the U.S., which initially began as a day to honor Union soldiers who had died in the Civil War and has since been extended to remember all U.S. service men and women.

Government buildings

As Memorial Day is a national holiday, all government buildings, including public schools, federal offices, and post offices will be closed Monday.

Financial institutions

Most banks will be closed for the holiday, but it's always best to check with your bank's branch to verify any modified hours they might have over the weekend as well as Monday. The stock and bond markets will also be closed Monday.

Retail stores

The vast majority of retail stores not only stay open during Memorial Day weekend, but they frequently have special sales for the holidays, including specific offers for members of the armed forces and their families.

Grocery stores

Most grocery store chains will remain open throughout the holiday weekend, so you can continue to stock up on last-minute cookout necessities whenever necessary. Liquor stores will close depending on the state.
