Michigan Time Zone

Michigan Time Zone was never in the Eastern Time Zone. It was always in the Central Time Zone (CST). Daylight Savings Time (DST) was the most significant adjustment, as CST is only one hour behind EST. As we now know, not every state observes DST, so the time difference between states fluctuates at various times of the year.

Michigan did not always observe DST, as they were in the same time zone as Chicago; however, many merchants determined that this was not suitable for them. Since they were not in the same time zone as New York and did not have as much daylight as they did, they felt an hour behind. Everything began in Detroit before neighboring communities such as Ann Arbor and Flint joined in. The entire state eventually followed suit, bringing us to the present.

What is The Time Zone?

A time zone is an area where, for legal, economic, and social purposes, a uniform standard time applies. Standard time zones are 15 degrees of longitude extensive.

A time zone is ideally one of 24 spherical lunes (a section on the globe in the north/south orientation) with equal width (15 degrees), each of which is assigned one of the 24 hours (makes up one day and one rotation of the Earth).

Typically, each section maintains a uniform standard time to monitor the day and night cycle. This indicates that all geographic regions within a given time zone observe the same time.

All of these time zones are defined by a number of hours offset from Coordinated Universal Time (UTC; see below), centered on the prime meridian (0°; since 1884, the Greenwich meridian).

Time Zone in Michigan

Two time zones exist within the state of Michigan. The vast majority, including cities like Detroit and Grand Rapids, is in the Eastern Time zone and observe daylight saving time, so there are two distinct clocks depending on the season.

  • Eastern Standard Time (EST) is five hours behind UTC/GMT.
  • Eastern Daylight Time (EDT): – 6 hours behind UTC/GMT.

Only the four counties in northern Michigan that border Wisconsin and account for about 9 percent of the state are in the Central Time zone. In addition, they observe daylight savings time, so there are two distinct clocks depending on the season.

  • Central Standard Time (CST) is six hours behind UTC/GMT.
  • Central Daylight Time (CDT) is seven hours behind UTC/GMT.

Eastern Time Zone in The United States

The eastern standard time zone includes the portion of the United States that lies west of 67(degrees) 30(seconds) West longitude and east of the boundary line described in Section 71.5, as well as the entirety of the state of Maine, but excludes Puerto Rico.

The Eastern Time Zone encompasses Connecticut, Delaware, a portion of Florida, Georgia, a portion of Indiana, a portion of Kentucky, Maine, Maryland, Massachusetts, a portion of Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, a portion of Tennessee, Vermont, Virginia, and West Virginia.

Five states span the eastern and central time zones. These five states are Florida, Indiana, Kentucky, and Michigan.

Central Time Zone in The United States

Moving Michigan and Indiana to Central Time is advantageous for farmers and others dependent on daylight because it is closer to astronomical time. The sun would be directly overhead closer to noon than it is now for these two Eastern Time Zone states at 1:00 p.m. Early risers would have more daylight hours, while early sleepers would find it simpler to fall asleep due to the earlier (by the clock) sunset.

When phoning home or the office from Chicago, tourists would not need to adjust their clocks or perform time zone gymnastics. People in Michigan, Wisconsin, Indiana, and Illinois would no longer be affected by distinct clock times. People in California would be that much closer to our time zone, giving us an additional hour of overlap to conduct business.

Daylight Savings Time (DST)

Michigan observes daylight saving time, as specified by the Uniform Time Act of 1966. Standard time changes to Daylight time during daylight savings, so CST becomes CDT and EST becomes EDT depending on the location.

It begins the second Sunday of March and concludes the first Sunday of November. In March, the clock is advanced from 2:00 am to 3:00 am, resulting in a loss of one hour of slumber. In November, the time will be set back an hour, from 3:00 a.m. to 2:00 a.m., giving you an extra hour of sleep. Clocks “spring forward and fall back” is a convenient method to remember the movement sequence.

The total duration of daylight savings is 34 weeks or approximately 65 percent of the year.

Benefits of Permanent Daylight Saving Time

Proponents of a permanent transition to daylight saving argue that more sunlight is beneficial for the body, the mind, and the economy. People are reportedly more active later in the day if there is more afternoon sunlight. As darkness falls later in the day, businesses benefit from an increase in consumers and a decrease in robberies and crime, according to some studies.

A CBS poll conducted last year found that 46 percent of Americans favor a permanent switch to daylight saving time, and 19 states (excluding Michigan) have enacted bills or resolutions to make DST permanent if Congress allows it.

Schedule a Phone Call from Michigan to Pennsylvania

Since Michigan (MI) and Pennsylvania (PA) have equivalent time zones, you can call someone during your regular hours and it will be the same time in both states. When scheduling a contact, remember to account for any time changes due to Daylight Savings Time.

If you reside in Michigan and wish to contact a friend in Pennsylvania, you may do so between 7:00 AM and 11:00 PM your time. This will occur between 7 AM and 11 PM their time, as Pennsylvania and Michigan share the same time zone.

If you’re available at any time but want to contact someone at work in Pennsylvania, you might try between 9:00 AM and 5:00 PM your time. The ideal time to contact them is between 9 a.m. and 5 p.m., during normal business hours.
