Donut chains nationwide will be giving away free donuts today because of a national holiday known simply as "Free Donut Day".
National donut day is always the first Friday in June and was originally started during World War 1.
The day is spent commemorating Salvation Army volunteers who braved the front lines in order to provide home cooked foods as a morale boost to soldiers. The donuts made in those days were often times cooked inside of the metal helmets of American soldiers.
Due to their fondness of the fried dough, American infantryman were often called “Doughboys”.
