What is the difference between EST and EDT? Are they both considered "Eastern" time?

Yes, both EST (Eastern Standard Time) and EDT (Eastern Daylight Time) are part of the Eastern Time Zone in the United States, but they are used at different times of the year.

EST (Eastern Standard Time) is UTC -5 hours and is used during the fall and winter months when Daylight Saving Time (DST) is not in effect. It generally runs from the first Sunday in November until the second Sunday in March.

  

EDT (Eastern Daylight Time) is UTC -4 hours and is used during the spring and summer months when Daylight Saving Time is in effect. It generally runs from the second Sunday in March until the first Sunday in November.

So, while both EST and EDT are considered "Eastern" time, the main difference is the time offset from UTC depending on whether or not DST is being observed.
