Title: Time in Michigan
Content:  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. In 1915, Detroit changed to Eastern time, followed by most of the rest of the state in 1931. In 1967, when the Uniform Time Act came into effect, the Upper Peninsula went under year-round CST, with no daylight saving time. In 1973, the majority of the peninsula switched to Eastern Time; only the four western counties of Gogebic, Iron, Dickinson, and Menominee continue to observe Central Time.

Title: State Line Trail
Content:  The State Line Trail is a lengthy, repurposed stretch of railroad right-of-way once used by the Chicago-based Chicago and Northwestern Railway (C&NW). At the time when standard time zones were being drawn throughout the United States, railroad corporations and their schedules played a key role in determining which locations were assigned to different time zones. After many changes to time zone boundary lines, almost all of Michigan was assigned to the Eastern Time Zone. However, four counties in the Upper Peninsula, historically, got much of their railroad service from the C&NW. These four counties, which include Gogebic County and Iron County, had developed a longtime attachment to the Chicago-oriented Central Time Zone. At these counties' request, they continue in that time zone today. The State Line Trail is in the Central Time Zone in its entirety.
Title: Upper Peninsula of Michigan
Content:  Like the entire Lower Peninsula, most of the Upper Peninsula observes Eastern Time. However, the four counties bordering Wisconsin are in the Central Time zone. In 1967, when the Uniform Time Act came into effect, the Upper Peninsula went under year-round CST, with no daylight saving time. In 1973, the majority of the peninsula switched to Eastern Time; only the four western border counties of Gogebic, Iron, Dickinson, and Menominee continue to observe Central Time. Daylight saving time is observed peninsula-wide.
