Sandwich Day is a holiday that celebrates one of the world's most popular foods. Most cultures have their own variation of the sandwich, so it’s worth celebrating on every continent. The sandwich was famously invented when the 4th Earl of Sandwich, John Montagu, ordered his food to be served between two slices of bread so that he could eat without having to stop his card game. Of course, food had been served between bread in other cultures prior to this, but this is how the popular dish got it’s name. People began saying “I’ll have the same as Sandwich”, and eventually it was simple called a sandwich. The date was probably chosen to correspond with the Earl’s birthday, which was in November 1718. Celebrate this holiday by making a sandwich for yourself or looking up new ways to make sandwiches from around the world.
