And the fans will be there in big numbers and ready to party if Spireites end their long exile in the National League.
It’s been an up and down time for the club over the last two decades, but the loyal fans have always been there through thick and thin.
We’ve seen promotions, relegations, Wembley visits, a ground change and the club fighting for its very survival.
Take a look at this gallery capturing just some of those moments and see if you can spot anyone you know.
We’d love to see your pics celebrating promotion. Send your images to [email protected]
