About ET
ET (Eastern Time) is a time zone used in the eastern regions of North America, including parts of the United States, Canada, and the Caribbean. The time zone operates as Eastern Standard Time (EST) at UTC−05:00 during the winter and Eastern Daylight Time (EDT) at UTC−04:00 during the summer daylight saving period.
Eastern Time is one of the most widely used time zones in North America and is commonly used for business, finance, broadcasting, and government operations. The time changes twice a year in areas that observe daylight saving time.
ET is followed in major cities such as New York, Washington, D.C., Toronto, Ottawa, Atlanta, Boston, and Miami. It serves as the primary time standard for many of the continent’s largest population and economic centers.
