What is Eastern Daylight Time (EDT)?
Eastern Daylight Time (EDT) is the daylight saving time offset for the US Eastern Time Zone. It is UTC-4, which is one hour ahead of Eastern Standard Time (EST, UTC-5). EDT is observed from the second Sunday of March to the first Sunday of November, covering roughly 8 months of the year.
During EDT, clocks are set forward by one hour to make better use of daylight in the evening. This means sunset occurs about an hour later compared to standard time, which is why it's called “daylight saving” time.
