Time in Michigan
All counties in Michigan's Lower Peninsula observe Eastern Time, as do most counties in the state's Upper Peninsula. The U.P. counties that do not, the four counties which have a land border with Wisconsin, are in the Central Time zone.
History
In 1967, when the Uniform Time Act came into effect, the Upper Peninsula went under year-round CST, with no daylight saving time.[1] In 1973, the majority of the peninsula switched to Eastern Time;[2] only the four western counties of Gogebic, Iron, Dickinson, and Menominee continue to observe Central Time.
