National Donut Day, a pseudo-holiday that honors the beloved breakfast pastry, occurs annually on the first Friday in June. It was established in 1938 by The Salvation Army as a way to honor the organization's Donut Lassies, women who traveled to France to serve donuts and other snacks to soldiers during World War I, USA TODAY reported.

Friday, June 6, is National Donut Day and you can get free treats at Duck Donuts, Dunkin', Krispy Kreme and Sheetz convenience stores.

All guests this Friday can receive a dozen Original Glazed doughnuts for just $2 with the purchase of any dozen at regular price in shop and via drive-thru at participating Krispy Kreme shops. Also on Friday, guests can receive any doughnut of choice for free – no purchase necessary.
