Difference Between Est And Utc

EST automatically adjusted to EDT time zone, that is in use

UTC (GMT/Zulu)-time: Monday, May 3, 2021 at 09:37:11. UTC is Coordinated Universal Time, GMT is Greenwich Mean Time. Great Britain/United Kingdom is one hour ahead of UTC during summer. Note: Time differences regularly change as countries observe varying Daylight Saving Time (DST) schedules. Although GMT and UTC share the same current time in practice, there is a basic difference between the two: GMT is a time zone officially used in some European and African countries. The time can be displayed using both the 24-hour format (0 - 24) or the 12-hour format (1 - 12 am/pm).

Universal Time Coordinated

Offset: UTC is 0 hours ahead Greenwich Mean Time (GMT) and is used in Universal

Coordinated Universal Time (UTC) is the world time standard that regulates clocks and time. It is successor to Greenwich Mean Time (GMT). For casual use, UTC is the same as GMT, but is used by the scientific community.
UTC is the time standard commonly used across the world since 1972. It is used in many technical fields, like aviation industry and meteorologists, also used to synchronize time across internet networks.

Main Difference – PST vs EST

PST and EST are two time zones that affect the American continent. PST stands for Pacific Standard Time whereas EST stands for Eastern Standard Time. The main difference between PST and EST is that PST is 8 hours behind the UTC (Coordinated Universal Time) whereas EST is 5 hours behind the UTC.

This article explains,

1. What is PST (Pacific Standard Time)?
– Definition, Offset Time, Regions under PST Time Zone

2. What is EST (Eastern Standard Time)?
– Definition, Offset Time, Regions under EST Time Zone

3. What is the difference between EST and EST?

What is PST

PST is also known as Pacific Standard Time or Pacific Time. This time zone is 8 hours behind the Coordinated Universal Time – UTC. This is also indicated as UTC -8. Time in this zone is calculated using the mean solar time of the 120th meridian west of the Greenwich Observatory. PST is used during the standard time in some parts of North America. It is typically used during winter because PDT (Pacific Daylight Time) is used during the summer since some areas use daylight saving time. During PDT, the time offset of this zone is UTC-7.

PST = UTC – 8

PDT = UTC – 7

The following regions or areas use the Pacific Standard Time:

Regions in USA under PST Time Zone

California

Washington

Nevada

Oregon (except Malheur county)

Idaho Panhandle

Regions in Canada under PST Time Zone

British Columbia (except some eastern communities)

Yukon

Tungsten

There are some other time zones that have the same offset time as PST but have different names. These time zones are

What is EST

EST, Eastern Standard Time or Eastern Time is 5 hours behind the UCT (Coordinated Universal Time). The time offset of EST is UTC-5. EST is used during the standard time in some areas of North America, Central America, and the Caribbean.

EST = UTC – 5

Areas in Caribbean under EST Time Zone

Bahamas

Haiti

Jamaica

Areas in Central America under EST Time Zone

Panama

6am utc to gmt. Colombia

Ecuador (except for Galápagos Islands)

Peru

Some regions observe daylight saving time during the summer, and therefore EDT (Eastern Daylight Time) is used in the summer. EDT is 4 hours behind the Coordinated Universal Time. However, some places such as Quintana Roo, Jamaica, Panama, Southampton Island in Nunavut use EST throughout the year.

Difference Between EDT and EST

There are some other time zones that have the same offset time as EST but have different names. These time zones are

NAEST – North American Eastern Standard Time
