Get it while you can! Nothing beats getting your favorite food for free, and Burger King knows it. The fast-food giant did, after all, recently treat fans to a full week of freebies—including the beloved Croissan’wich and the decadent Hershey’s Sundae Pie—to help us power through Daylight Saving Time.

St. Patrick’s Day brought luck to Burger King fans! The fast food chain will celebrate this iconic date with all of its customers by offering a free order of onion rings. Here are all the details so you don’t miss out on yours.

Burger King is offering free onion rings for St. Patrick's Day, as well as its Combo Combination promotion. This comes on the heels of its weeklong Daylight Savings Time breakfast promotion, which helps customers cope with losing an extra hour of sleep.
