20+ Differences between Mountain Time vs. Eastern Time (Explained)

Mountain Time and Eastern Time, two crucial time zones for North America, are separated by two hours. Mountain Time and Eastern Time follow GMT (Greenwich Mean Time) or UTC, the same methods of keeping time used by the rest of the world (Coordinated Universal Time). 

However, during daylight saving time, these times are modified by one hour. The two time zones will be covered in more detail in this article.

Key Differences Between Mountain Time and Eastern Time:

Mountain Time:

• Mountain time, also known as MST, is used for North American time.
• MST is observed during the shortest daylight hours of Autumn and winter.
• UTC-6 or UTC-7 is MST.
• MST follows EST by two hours.
• MST workdays typically last from 9:00 am to 4:00 pm.
• MST is measured using the 105th meridian’s mean solar time west of the Greenwich Observatory.
• The MST is observed in Texas, Kansas, Utah, and Arizona, among other states.

Eastern Time:

• Eastern Time, also known as EST, is the timezone for the East coast of North America.
• EST is the time of day during the winter.
• EST is UTC-4 or UTC-5.
• EST is two hours ahead of MST.
• Meetings and other similar events in EST should be held between 11:00 am and 6:00 pm.
• The Eastern Standard Time (EST) is calculated using the mean solar time of the 75th meridian west of the Greenwich Observatory.
• EST is followed by New York, New Jersey, and Connecticut states.

What is Mountain Time?

MST is the time zone in North America. Another name for it is Mountain Time Zone (MTZ). It is known as Mountain Time (MT) or Daylight Saving Time (DST) in the United States and Canada (MST).

It is 7 hours in North American standard time, or Greenwich Mean Time (GMT). It’s popular in the United States, Canada, and Mexico. MST is defined as UTC-6 or UTC-7.

MST is currently monitoring the 105th meridian west of the Greenwich Observatory. MST workdays typically run from 9:00 am to 4:00 pm.

Mountain Daylight Time (MDT) is the standard time zone that adds an hour to the clocks for summertime daylight saving time MST. Every year, MST begins and ends on the same day and time.

What is Eastern Time:

EST is recognized as the standard time zone for North America. Greenwich Observatory or Greenwich Mean Time will be five hours (GMT). The earth rotates around the sun, creating time zones in various locations.

Because of the difference between these time zones, it is the night at one end of the world while it is the day at the other. A variety of longitudinal lines defines the time zone on earth. It refers to local time or common standards.

As a result, there are 24 central time zones based on Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT). The time zones are adjusted as the seasons’ change. For example, daylight savings time replaces standard time. In the summer, it switches to “Summertime,” which is standard time plus one hour.

EST is one of the most common time zones. During the summer, however, it observes Eastern Daylight Time in some locations for daylight saving (EDT).

Mountain Time vs. Eastern Time – All you need to know

Mountain Time:

1. North America’s time zone is known as MST. 
2. Its alternate name is Mountain Time Zone (MTZ). 
3. Mountain Time (MT) or (MST) is the time zone. 
4. The time difference between now and North American standard time, or Greenwich Mean Time (GMT), is seven hours. 
5.  MST is either UTC-6 or UTC-7.
6. MST follows EST by two hours.
7. The MST is one hour behind Central Time Zone.
8. MST is measured using the 105th meridian’s mean solar time west of the Greenwich Observatory.
9. MST is observed during the shortest daylight hours of fall and winter.
10. Alberta, British Columbia, and the Northwestern Territories are Canadian provinces that use MST as their standard time.

Eastern time:

1. The time zone followed by the people of the east coast of North America is EST. 
2. Greenwich Observatory or Greenwich Mean Time (GMT) was 5 hours ago. 
3. Various places have different time zones because the earth circles on its axis around the sun.
4.  Because of the time zone difference, it is sunlight in one part of the world while darkness falls in another. 
5. EST is either UTC-4 or UTC-5
6. EST is two hours ahead of MST.
7. Eastern Standard Time is one hour ahead of Pacific Time.
8. The Eastern Standard Time (EST) is calculated using the mean solar time of the 75th meridian west of the Greenwich Observatory;
9. Winter EST is the time frame.
10. Since the US Capital is situated in EST, EST is the country’s recognized time zone;

Key Features: Mountain Time vs. Eastern Time:

Mountain Time:

1. The Mountain Time Zone (MT) is often known as North American Standard Time. 
2. This is referred to as Mountain Time (MT) or Mountain Standard Time (MST) in the United States and Canada during standard time and Mountain Daylight Time (MDT) during daylight saving time.
3. Continuously, Mountain Time is computed about Coordinated Universal Time. Due to its western location, it is always behind UTC.
4. MST is measured using the 105th meridian’s mean solar time west of the Greenwich Observatory.
5. Standard time is used to determine MST, which is determined by subtracting seven hours from UTC.
6. When considering the impact of DST, MDT is calculated by subtracting six hours from UTC.

Eastern Time:

1. The Eastern Time Zone (ET), often known as North American Eastern Standard Time, is found throughout the Western Hemisphere (NAEST). 
2. This is known as Eastern Standard Time (EST) throughout the east coast of North America in the winter and Eastern Daylight Time (EDT) in the summer.
3. Eastern time is determined relative to UTC like mountain time is. It distinguishes between standard time and daylight saving time.
4. The Eastern Standard Time (EST) is calculated using the mean solar time of the 75th meridian west of the Greenwich Observatory.
5. .Standard time (EST) is determined by subtracting five hours from UTC.
6. To account for DST, UTC is reduced by four hours to calculate EDT.
