Time in Michigan

Michigan observes Eastern Time, except for four counties and two cities, which observe Central Time.

History

Before time zones were introduced, every place used local observation of the sun to set their clocks, which means they used local mean time, every city different based on their longitude. Detroit used 05:32:11 west of Greenwich and Menominee 05:50:27 west of Greenwich.

Time zones were introduced in the United States in 1883. They were introduced in different years based on local decisions. Michigan adopted Central Standard Time throughout the state effective September 18, 1885.{{Cite news|date=1885-09-19|title=MICHIGAN'S EARLY TIME.|language=en-US|newspaper=The New York Times|url=https://www.nytimes.com/1885/09/19/archives/michigans-early-time.html|access-date=2021-02-24|issn=0362-4331|quote=... among the laws now in force are the 10-hour labor law and an enactment making central standard time legal in this State.}}{{Cite news|date=1885-09-12|title=Standard Time Adopted|url=http://www.newspapers.com/image/117691069/|access-date=2021-02-24|newspaper=The Detroit Free Press|language=en-US}}{{Cite news|date=1885-09-18|title=STANDARD TIME|work=The Detroit Free Press|url=https://www.newspapers.com/image/117691126/|access-date=2021-02-24|language=en-US|quote=Standard time becomes legal in Michigan this morning.}} In 1915, Detroit changed to Eastern time to be on the same time zone as New York,{{Cite web |last=Gordon |first=Lauren|date=2022-03-14 |title=Remember The Time: Michigan Was Once Part of the Central Time Zone |url=https://wkfr.com/michigan-central-time-zone/ |access-date=2024-06-06 |website=103.3 WKFR |language=en}} followed by most of the rest of the state in 1931.{{Cite web|date=2017-07-28|title=Why is Michigan on Eastern Time?
