Pacific Time is the US West Coast time zone: UTC−8 in winter (Pacific Standard Time) and UTC−7 in summer (Pacific Daylight Time). British Columbia used it until 2026, but BC now stays at UTC−7 all year, so from November to March BC is an hour ahead of Seattle.
PST in winter, PDT in summer.
Clocks go forward one hour at 2 AM on the second Sunday in March and back one hour at 2 AM on the first Sunday in November.
