EST vs. MST
The abbreviation of EST is Eastern Standard Time, while MST stands for Mountain Standard Time. The time zone of the Western Hemisphere is called Eastern Time Zone (ET), and the time along the east coast of North America is known as the Eastern Standard Time (EST). The time zone of North America is known as the Mountain Time Zone (MTZ). In the United States and Canada, this is called Mountain Standard Time (MST) or Mountain Time (MT).
EST is UTC-4 or UTC-5, whereas MST is UTC-7 or UTC-6. EST is the period during winter. And during summer, the time zone is known as Eastern Daylight Time (EDT). MST is at the standard time and the period during the shortest days of autumn and winter. At the daylight savings time, it is known as Mountain Daylight Time (MDT). EST is 2 hours before MST; on the other hand, MST is two hours after EST.
The most convenient time in EST to hold meetings and the like is between 11:00 am and 6:00 pm. In MST, the usual working time is between 9:00 am and 4:00 pm. Concerning the Pacific Time Zone, MST is one hour ahead of it. When talking about the Central Time Zone, MST is one hour behind it. States that observe EST are New York, New Jersey, and Connecticut. The states that follow the MST are the states of Texas, Kansas, Utah, and Arizona.
What is EST?
EST is the time zone followed in North America. It is 5 hours before the Greenwich observatory or Greenwich Mean Time (GMT). As the earth revolves on its axis around the sun so, different places are having different time zones. Due to the difference in time zone, there is nighttime at one end of the world, during the daytime in another. The time zone of the earth is bounded by different longitudinal lines. These lines include uniform standards or local time.
So the total central time zones are 24, which are based on the (GMT) Greenwich Mean Time or (UTC) Coordinated Universal Time. The Time zones are adjusted with the change in seasons. ‘Standard time’ gets converted to the ‘daylight savings time’ zone. In summer, it changes to ‘summertime’ zone, which is standard time plus one hour.
EST is used in the following countries: Bahamas, Canada, Haiti, Jamaica, Cayman Islands, Mexico, Panama, Turks & Caicos Is, United States. The principal city in the EST timezone is New York City from the USA with other main cities, e.g., Toronto, Montreal, Brooklyn, Borough of Queens. EST is known to be one of the standard time zones. But for daylight saving in some places during summer, it observes Eastern Daylight Time (EDT).
