What Is Pacific Standard Time?

Pacific Standard Time is the westernmost time zone in the contiguous United States and Canada. It is also used in Baja California, Mexico.

It covers all or parts of five states in the US and two provinces or territories in Canada.

The PST time zone is the third most populated time zone in the US. It spans from Canada to Mexico.

In North America, Pacific Standard Time shares a border with Mountain Standard Time (MST) in the east.

Pacific Standard Time Zone

Pacific Standard Time (PST) 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. Pacific Daylight Time (PDT) is used during the remainder of the year.

PST Is the Pacific Time Zone

In everyday usage, PST is often referred to as Pacific Time (PT) or the Pacific Time Zone. This can add a bit of confusion as the term Pacific Time does not differentiate between standard time and Daylight Saving Time, so Pacific Time switches between PST and PDT in areas that use DST during part of the year.

Most North American time zones also have generic terms, including Mountain Time (MT), Central Time (CT), Eastern Time (ET), and Atlantic Time (AT).
