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
Oregon (except Malheur county)
Regions in Canada under PST Time Zone
British Columbia (except some eastern communities)
Areas in Mexico under PST Time Zone
There are some other time zones that have the same offset time as PST but have different names. These time zones are
U – Uniform Time Zone
AKDT – Alaska Daylight Time
PST – Pitcairn Standard Time
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
The following regions or areas use the Eastern Standard Time:
Regions in USA under EST Time Zone

Most parts of Ontario, Quebec and Nunavut
Areas in Mexico under EST Time Zone
Areas in Caribbean under EST Time Zone
Areas in Central America under EST Time Zone
Ecuador (except for Galápagos Islands)
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.
