Founded in 2017 by National Day Calendar® to celebrate South Dakota as the 40th state to join the Union. National Day Calendar is committed to celebrating every aspect of our nation's diverse culture and history, which is why we proudly introduced National State Days. This initiative is our way of honoring each state in the order they joined the Union, offering a dedicated day to celebrate the unique heritage, achievements, and spirit of each state.
