Ohio Time Zone

In the United States of America (USA), the Ohio Time Zone is in the Eastern Time Zone. Greenwich Mean Time is five hours behind Eastern Standard Time (EST). Ohio, one of the smallest but most populous states in the United States, is located in the Midwest, specifically in the Great Lakes region.

The state shares borders with Indiana, West Virginia, Kentucky, Michigan, and Pennsylvania, in addition to Lake Erie, one of the five Great Lakes of North America. Ohio, unlike many other states that span multiple time zones, is wholly located in the Eastern Time Zone.

What is Time Zone?

A time zone is a region that utilizes a standardized time for all social, commercial, and legal purposes. By longitude, the Earth is roughly subdivided into 24 regions (time zones). Each line of longitude is subdivided by fifteen degrees; as a general rule, and depending on the direction of transit, time advances or regresses one hour for every fifteen degrees of longitude.

Time Zone in Ohio

Ohio is located in the Eastern Time zone. There are no exceptions to the state’s uniform time zone for counties and cities. Due to daylight savings time, Ohio has two distinct clocks depending on the time of year.

You will remain in the same time zone when traversing the borders with Pennsylvania, West Virginia, Kentucky, Indiana, or Michigan. When traveling further into Kentucky, Indiana, or northern Michigan, however, you will enter the Central Time zone.

In addition, crossing the Canadian border will not result in a time zone change.

Daylight Savings Time (DST)

Ohio observes daylight saving time, as specified by the Uniform Time Act of 1966. During daylight savings, Eastern Standard Time (EST) is replaced by Eastern Daylight Time (EDT).

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.
