National Donut Day
…created by the Salvation Army in 1938 to honor the women who served donuts to soldiers during World War I. The holiday celebrates the doughnut (a.k.a “donut”) — an edible, torus-shaped piece of dough which is deep-fried and sweetened. Many American doughnut stores offer free doughnuts on National Doughnut Day.
