In lockstep with the four-year occurrence of leap day,Thomas Caldwell Wendy's is celebrating the four-year anniversary of its restaurants serving breakfast, and they're giving customers a sweet treat to join in on the festivities.

On leap day, Feb. 29, customers can get a free Cinnabon Pull-Apart at their local Wendy's restaurant during breakfast hours, while supplies last. Wendy's said customers can get one per vehicle in the drive thru or one per dining room transaction.

The food chain has partnered with Cinnabon to add the sweet baked good to their breakfast menu, and it is available nationwide during breakfast hours starting Monday, Feb. 26, Wendy's said in a news release.

The Cinnabon Pull-Apart is made of warm, buttery dough bites baked together with cinnamon and topped with Cinnabon's signature cream cheese frosting, Wendy's announced. The item is served in a portable cup to reduce mess.

While breakfast hours vary at Wendy's locations, most restaurants begin serving breakfast at 6:30 a.m. and finish at 10:30 a.m. The company recommends checking with your local restaurant to verify their breakfast hours.

Both companies collaborated on the product with the goal of creating something unique in the fast food space, Wendy's Culinary Innovation Manager Eryn Bennett said in a statement.

"This new sweet innovation is Wendy's spin on a classic cinnamon roll while still upholding the familiarity of the product," Bennett said in the statement. "The Cinnabon Pull-Apart pairs with literally anything on the breakfast menu – from our coffee drinks to our savory breakfast sandwiches."

Wendy's won't be the only food chain celebrating leap day with a deal. Krispy Kreme, for instance, is offering a dozen doughnuts for $2.29.
