Time zones in South Dakota now
Time zone in South Dakota
South Dakota has 2 different clock settings under the current rules, from MST (UTC−7) in Denver to CDT (UTC−5) in Chicago. The clock at the top shows Chicago on Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) in summer.
The IANA time zone database divides South Dakota into 2 zones. It needs more zones than there are clock settings because it also records history: two regions that keep the same time today get separate entries if their clocks differed at any point since 1970.
Chicago lies at 87.7° west, where mean solar time is UTC−5:51 (four minutes per degree of longitude). That is within 9 min of its standard time, so the sun is highest close to noon in winter, and about 1:00 PM in summer.
Daylight saving time in South Dakota
In Chicago clocks move forward one hour on the second Sunday of March at 2:00 AM and back on the first Sunday of November at 2:00 AM (local time).

All coming change dates are on the America/Chicago page.
Clock history of South Dakota
Chicago has kept the same clocks as Chicago since at least 1970: tzdata records both under America/Chicago. Clocks have moved for daylight saving time every year since 1970. Before 1970 local practice could differ from Chicago’s, and tzdata does not track it separately; the year-by-year table, which starts with Chicago’s local mean time, is on the America/Chicago page.
