Time zones in Iowa

ZoneIANAStandardDaylightAbbr
Central TimeAmerica/ChicagoUTC−6UTC−5CST / CDT

All of Iowa runs Central Time (CST/CDT, UTC−6 in winter, UTC−5 in summer), with no Eastern or Mountain areas; its city Des Moines follows the same clock.

Crossing the state line

Every state bordering Iowa — Minnesota, Wisconsin, Illinois, Missouri, Nebraska, and South Dakota — is on Central Time where it meets Iowa, so no Iowa state line changes the clock. Mountain Time only starts hundreds of miles west, in the Nebraska Panhandle and western South Dakota.
