Did you know National Donut Day was started to pay tribute to Salvation Army Workers who served donuts to the military during WWI. That was news to me.
National Doughnut Day, or National Donut Day — celebrated in the United States and in some other countries, is on the first Friday of June of each year, succeeding the Doughnut event created by The Salvation Army in Chicago in 1938 to honor those of their members who served doughnuts to soldiers during World War I. The holiday celebrates the doughnut. Many American doughnut stores offer free doughnuts on National Doughnut Day.
