Eastern Standard Time (EST)

Introduction

Eastern Standard Time (EST) is the time zone used in the eastern part of North America, including parts of the United States, Canada, and Mexico. It is five hours behind Coordinated Universal Time (UTC-5). This time zone is used to standardize time across multiple regions, ensuring consistency in scheduling and communication. During the summer months, Eastern Daylight Time (EDT) is observed, which is four hours behind Coordinated Universal Time (UTC-4).

Time Zone History

The history of Eastern Standard Time dates back to the late 19th century when the need for standardized time became apparent due to the expansion of the railroad system. On November 18, 1883, known as "The Day of Two Noons," railroads in the United States and Canada adopted standard time zones, including EST, to improve scheduling and safety. The Interstate Commerce Commission (ICC) took over time-zone management from railroads in 1938, and the boundaries of the Eastern Time Zone have since moved westward. The Uniform Time Act of 1966 introduced daylight saving time for the Eastern Time Zone, which was later extended by the Energy Policy Act of 2005.

Geographical Coverage

Eastern Standard Time is observed in several regions, including parts or all of 23 states in the eastern United States, parts of eastern Canada, and the state of Quintana Roo in Mexico. The time zone spans from northern Canada to Panama near the equator. In North America, Eastern Standard Time shares a border with Atlantic Standard Time (AST) in the east and Central Standard Time (CST) in the west.

Daylight Saving Time (DST)

Eastern Standard Time observes daylight saving time, known as Eastern Daylight Time (EDT), during the summer months. During this period, the time is advanced by one hour, making it four hours behind Coordinated Universal Time (UTC-4). Daylight saving time typically starts on the second Sunday in March and ends on the first Sunday in November. This practice helps to make better use of daylight during the longer days of summer.
