National Tater Day is observed worldwide every March 31, celebrating all kinds of potatoes and the numerous dishes that can be made with them. The holiday likely originated in the mid-19th century in Kentucky, where sweet potatoes were a significant cash crop, and it has since expanded to include all potato varieties. Traditionally, people celebrate by enjoying potato dishes for breakfast, lunch, and dinner, sharing recipes online with hashtags like #NationalTaterDay, and experimenting with new potato recipes. The city of Brenton, Kentucky, hosts an annual Tater Day sweet potato festival featuring pageants, competitions, and various community activities. While National Tater Day focuses on both sweet and common potatoes, it should not be confused with National Potato Day, which occurs on August 30.
