About sunrise in South Dakota
The sun reaches Sioux Falls 27 minutes before Rapid City today — that gap is longitude, and it is fixed: the Earth turns fifteen degrees an hour, so every degree of longitude is four minutes of sunrise. South Dakota also spans 2 time zones, so two cities can see the sun at the same instant and read different clock times.
Eastern South Dakota, including Sioux Falls, is on Central Time. The western half, including Rapid City and the Black Hills, keeps Mountain Time.
