About time in Sioux Falls
Sioux Falls, seat of Minnehaha County and South Dakota's largest city, grew up around the falls of the Big Sioux River in the state's southeastern corner — the Central Time side of a split state.
South Dakota's zone boundary runs roughly along the Missouri River: East River communities such as Sioux Falls keep Central Time, while West River, including Rapid City and the Black Hills, is on Mountain Time. Driving west on I-90 toward Rapid City means setting the clock back an hour partway across the state.
Summer days here run to about 15 hours 20 minutes at the solstice; late-December daylight is closer to 9 hours, with the sun down around 5:00 PM CST.
