Sinker buff alert: Mark down June 5 as a red letter day on your calendar because that’s when Dunkin’ Donuts plans to celebrate National Doughnut Day with a giveaway of sorts.

For folks unacquainted with the movable feasts of the culinary calendar, National Doughnut Day falls on June 5 this year, and on that blessed day, Dunkin’ Donuts, the Canton-based coffee-and-baked-goods chain, said that participating stores nationwide “will give every customer a free donut of their choice, with the purchase of any beverage, limit one per customer.”

And that’s not all. The chain has been conducting its first-ever “Create Dunkin’s Next Donut” contest. From nearly 130,000 donut submissions, 12 finalists have been chosen, and on National Doughnut Day, Dunkin’ plans to announce the $12,000 grand prize winner.

Foodies may want to go easy at the eats table in the middle part of next week. As careful readers of this space may recall, Friendly Ice Cream Corp., the Wilbraham company that operates the Friendly’s chain of more than 500 family restaurants, plans to hold a Free Ice Cream Day from noon to 5:00 p.m on Saturday, June 6.

So there you have it. Doughnuts on Friday. Ice cream on Saturday. For the undisciplined gourmet, excessive avoirdupois may run rampant in early June.
