About Pacific Standard Time (PST)
Pacific Standard Time (PST, IANA: America/Los_Angeles) is the standard time zone for the US West Coast and Canadian westernmost provinces, set at UTC-8:00. PST is observed from the first Sunday in November to the second Sunday in March per the Uniform Time Act of 1966; the region switches to Pacific Daylight Time (PDT = UTC-7:00) the rest of the year. PST is used by ~50 million people in California, Oregon, Washington, Nevada (most), British Columbia, Yukon Territory, and the Mexican states of Baja California Norte. Major cities: Los Angeles, San Francisco, San Diego, Seattle, Portland, Sacramento, Las Vegas, Vancouver BC. PST is the time zone of US tech hubs (Silicon Valley, Seattle, Vancouver) — global software-release coordination, Big-Tech corporate-earnings calls, Hollywood production schedules, and NYSE/Nasdaq market hours (PST 06:30-13:00) all reference PST/PDT. Mexico abolished DST nationwide in 2022 except for border zones, complicating Baja conversions.
About Mountain Daylight Time (MDT)
Mountain Daylight Time (MDT, IANA: America/Denver during DST window) is the summer-time variant of MST, set at UTC-6:00 — observed from the second Sunday in March to the first Sunday in November per the Energy Policy Act of 2005. MDT shares the same UTC offset as Central Standard Time (CST), which can cause cross-time-zone scheduling confusion during the DST transition windows in March and November. The Navajo Nation in northeastern Arizona does observe MDT (unlike the rest of Arizona), creating one of the rare US sub-state time-zone exceptions per the Navajo Nation Council's 1968 resolution. MDT applies in Colorado, Utah, Wyoming, Montana, Idaho east, New Mexico, parts of Texas, and Canadian Rocky Mountain provinces (Alberta, eastern BC). Used in coordination of: Denver International Airport flight operations, ski-area lift hours during shoulder-season DST window, Yellowstone National Park ranger schedules, US National Renewable Energy Lab operations, and FAA Albuquerque ARTCC ATC operations.
