Every September 18, Americans celebrate National Cheeseburger Day, and this year is no different. The foodie holiday is marked by some of the biggest names in fast-food and casual dining serving up incredible offers, ranging from half-priced burgers to buy-one-get-one free sliders.

According to USA Today, YouGov’s rankings state that hamburgers and cheeseburgers are among the most-loved American dishes, with cheeseburgers taking sixth place on the list. With Americans consuming an estimated 30 billion burgers annually, it is no wonder this day has become a much-anticipated celebration.
