Put a Pillow on Your Fridge Day may sound like a crazy thing to celebrate, but it’s actually a holiday with a rich traditional history. Before refrigerators people used small, cool rooms called larders to store their perishable foods. At that time people believed that putting linens in the larder once a year would bring good luck to their households. This tradition continued after the invention of the refrigerators, when it evolved into the current version: putting a pillow on your fridge! This is a great holiday to participate in if you want to bring good luck to your household for the rest of the year.
