EST to GMT Converter

Understanding EST to GMT Time

Eastern Standard Time (EST on Wikipedia) is a North American time zone that subtracts five hours from Coordinated Universal Time (UTC−05:00) when observing standard time. During daylight saving time (EDT), it becomes UTC−04:00.

Greenwich Mean Time (GMT on Wikipedia) is the mean solar time at the Royal Observatory in Greenwich, London. It’s often used as a reference point for other time zones, though Coordinated Universal Time (UTC) is now generally preferred for scientific and navigational purposes.
