Basically the answer is no at according to these comments, at least not as truly stand alone state holidays. Fastnacht is still Mardi Gras or Fat Tuesday, a different celebration but for the same reason and on the same day. Groundhog Day is celebrated in elementary schools nationwide and a whole blockbuster movie exists based on it. First day of hunting season is, as mentioned, a day off school in many other rural locations. Flag Day is a federal holiday, as are all the holidays listed on the state website as state holidays.
