From Wikipedia: National Donut Day or National Doughnut Day, celebrated in the United States and in some other countries, is on the first Friday of June of each year, succeeding the donut event created by The Salvation Army in Chicago in 1938 to honor those of their members who served donuts to soldiers during World War I.

No matter what flavor donut you have, may it be a sweet celebration of fried dough. Also, a coffee of your choosing makes it even better.
