Pacific Standard Time (PST)
Pacific Standard Time (PST) is UTC-8. California, Washington, most of Oregon and Nevada, most of British Columbia and Baja California use PST in winter and Pacific Daylight Time (PDT, UTC-7) from the second Sunday in March to the first Sunday in November. Yukon left Pacific Time in 2020 and now stays on UTC-7 all year.
