What is open and closed on Memorial Day weekend?

Around 37 million Americans are expected to travel more than 50 miles this Memorial Day weekend, according to American Automobile Association. Some people and families are planning to travel as COVID-19 restrictions and mask mandates for those vaccinated have eased since last year.

Whether you are out and about or staying at home, be aware that some usual services and stores may be closed this weekend. Memorial Day became a federal holiday in 1971. Originally, it was known as Decoration Day, a Civil War-era tradition in which loved ones decorated the graves of soldiers at the end of May. Today, it honors soldiers who have died in uniform.

Whether enjoying the holiday's sales or preparing for a road trip, here's a list of what will be open and closed on Memorial Day.

Grocery stores and restaurants

Major grocery stores will remain open although their normal businesses hours may be adjusted. You can check your local grocery store's website for their hours of operations. An alternate option would be Amazon Fresh, Shipt or Instacart, which delivers groceries even on Memorial Day. However Costco Wholesale will be closed on Monday.
