Time Zones

Pacific Standard Time (PST)

Introduction

Pacific Standard Time (PST) is the time zone for the westernmost parts of the contiguous United States and Canada, as well as Baja California in Mexico. It has a time offset of UTC-8. This time zone is used to standardize time across these regions, ensuring consistency and coordination in daily activities and business operations. During daylight saving time, the offset changes to UTC-7, known as Pacific Daylight Time (PDT).

Time Zone History

Pacific Standard Time was established to provide a uniform time standard for the western regions of North America. The time zone has remained consistent with a UTC-8 offset during standard time and UTC-7 during daylight saving time. The adoption of standardized time zones in the United States and Canada in the late 19th century was driven by the need for a reliable timekeeping system for the expanding railroad networks. The Uniform Time Act of 1966 in the United States further solidified the use of daylight saving time, which is observed from the second Sunday in March to the first Sunday in November.

Geographical Coverage

Pacific Standard Time is observed in the following regions:

  • United States: California, parts of Idaho, Nevada, Oregon, and Washington.
  • Canada: British Columbia, except for some eastern communities.
  • Mexico: Baja California.

These regions are known for their diverse landscapes, including coastal areas, mountains, and forests.

Daylight Saving Time (DST)

Pacific Standard Time observes Daylight Saving Time (DST), shifting the time offset to UTC-7 during the summer months. DST starts on the second Sunday in March and ends on the first Sunday in November. This practice provides more daylight during the evening hours in the summer, aligning with the rest of North America and enhancing energy conservation.
