When it comes to delicious and juicy food, hamburgers are literally everyone's go-to choice- from kids to older adults. Especially in America, where according to the United States Department of Agriculture (USDA) people consume an average of 2.4 burgers per day, which is about 50 billion burgers every year. Thus, it wouldn't be surprising to anyone that the state celebrates what is called National Hamburger Day every year and in 2025 it is being celebrated on May 28, with big brands selling the snack offering free burgers in its honour.
If you are someone who loves themselves a good and juicy burger then get ready to indulge in the cravings with wallet-saving deals by brands such as Burger King, Wendy's, Shake Shack and more.
