What Is Eastern Standard Time?
Eastern Standard Time Zone
Eastern Standard Time (EST) is a standard time zone in use from the first Sunday in November to the second Sunday in March—when Daylight Saving Time (DST) is not in effect. Eastern Daylight Time (EDT) is used during the remainder of the year.
EST Is the Eastern Time Zone
In everyday usage, EST is often referred to as Eastern Time (ET) or the Eastern Time Zone. This can add a bit of confusion as the term Eastern Time does not differentiate between standard time and Daylight Saving Time, so Eastern Time switches between EST and EDT in areas that use DST during part of the year.
Converting Eastern Time to Other US Time Zones
- Eastern Standard Time (EST) is 1 hour ahead of Central Standard Time (CST).
To convert EST to CST, you have to subtract one hour.
- Eastern Standard Time (EST) is 2 hours ahead of Mountain Standard Time (MST).
To convert EST to MST, you have to subtract two hours.
- Eastern Standard Time (EST) is 3 hours ahead of Pacific Standard Time (PST).
To convert EST to PST, you have to subtract three hours.
