Pacific Standard Time (PST) operates at UTC−8 and is widely used along the west coast of North America, including parts of the United States, Canada, and northwestern Mexico, as the standard time during the winter months. It is also commonly referred to as "Pacific Time." During the summer, regions observing PST generally transition to Pacific Daylight Time (PDT, UTC−7) as part of daylight saving time practices.
Importance and Global Use of PST
Pacific Standard Time plays a vital role in synchronizing business, transportation, broadcasting, and digital services across some of North America's most economically significant regions, such as California, Washington, British Columbia, and Baja California. These areas are hubs for technology, entertainment, and trade, making PST critical for consistent scheduling and coordination both locally and internationally.
Globally, PST supports connections across the Pacific Rim, acting as a time bridge between Asian markets and North American operations. Its position between Eastern Time in the US and time zones in East Asia allows for efficient cross-continental collaboration, which is essential for industries that rely on real-time communication and 24-hour global supply chains.
