National Cheeseburger Day

If you love cheeseburgers, today is the day you’ve been waiting for.

National Cheeseburger Day is a made-up U.S. holiday – but Canadians can jump on the bandwagon, too.

McDonald’s Canada is taking part in the festivities, and is extending the celebration to last through Sept. 24, so you’ve got a whole week to grab a free burger. The catch is you still have to spend at least $1 on food or a beverage and the deal is limited to one burger per person for the entire week.

The burger has a long and storied history. Tracing its origins back to Ghengis Khan and his Mongol army. They would take raw meat and place it between their horse and saddle to tenderize the meat, a delicacy that became known as steak tartare. From there, it made its way to the German city of Hamburg, where the modern hamburger began to take shape.

Then, sometime in the late 1920s or early ’30s, someone in the United States decided to add cheese.

History is unclear on exactly who was the brainchild behind the cheeseburger, but we do know that the bacon cheeseburger was invented by American Dale Mulder in his A&W Restaurant in 1963.
