What's open and closed on Memorial Day

In what had long been celebrated every May 30 to honor America’s fallen soldiers, Memorial Day officially became a federal holiday in 1971, observed on the last Monday in May. Businesses increasingly have chosen to stay open on the holiday, leading to what is now one of the biggest retail sales and travel weekends of the year. Government offices, post offices and schools are closed, as is the stock market, banks and a handful of businesses. The vast majority of retailers will be open, with many trying to lure customers with big promotional sales. Hours may vary by location.
