National cheeseburgers day doesn't have any historical significance. But there is some arguments regarding the arrival of burger. Few places such as Pasadena, California ,claims to be the birthplace of burger ,there, a 16-year-old short-order cook serving the first cheeseburger more than 100 years ago in a roadside hamburger stand. Other places including Kaelin's restaurant in Louisville in 1934 also claimed to be the birthplace of burger and also credited by naming it a cheeseburger.
