The term Pacific Time (PT) is often used to denote the local time in areas observing either Pacific Standard Time (PST) or Pacific Daylight Time (PDT).

What Is Pacific Time?

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

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

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

What Does PT Time Zone Mean?

Unlike other time zone denominations, which have a fixed time, Pacific Time refers to a geographical area where the time changes twice yearly as Daylight Saving Time (DST) begins and ends. Pacific Standard Time is UTC-8, while Pacific Daylight Time is UTC-7.

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