What does ET mean?

Eastern Time (ET) is a time zone used in the eastern part of North America.
ET can refer to either Eastern Standard Time (EST) or Eastern Daylight Time (EDT), depending on whether daylight saving time is in effect or not.
During the winter months when daylight saving time is not in effect, Eastern Time is equivalent to Eastern Standard Time (EST), which is five hours behind Coordinated Universal Time (UTC−05:00). However, during the summer months when daylight saving time is in effect, Eastern Time is equivalent to Eastern Daylight Time (EDT), which is four hours behind Coordinated Universal Time (UTC−04:00).
