North America runs five continental-US timezones (Eastern, Central, Mountain, Pacific, Alaskan) plus Newfoundland (a 30-minute offset from Atlantic Time — one of the few 30-minute timezones outside Asia). DST is nearly universal (except Arizona, Hawaii, most of Saskatchewan) and runs March → November. Business scheduling defaults to Eastern for multi-office US corporations regardless of headquarters.
Seattle operates on the America/Los_Angeles timezone, switching between PST (Pacific Standard Time, UTC −8:00) in winter and PDT (Pacific Daylight Time, UTC −7:00) from mid-March to early November. Seattle is the Pacific Northwest's largest city and shares its timezone with the entire US West Coast from California to Washington state, as well as British Columbia in Canada (where Vancouver observes the same PST/PDT schedule).
Seattle is home to two globally influential technology companies — Amazon (headquartered in South Lake Union) and Microsoft (headquartered in nearby Redmond) — making Pacific Time increasingly relevant for enterprise software, cloud computing, and e-commerce scheduling worldwide. Amazon Web Services (AWS) and Microsoft Azure operational schedules, maintenance windows, and release cycles are frequently communicated in PST/PDT.
Seattle is also a major maritime port — the Port of Seattle is one of the busiest container terminals on the US West Coast — with significant trade flows to and from Asia. Container ship scheduling across the Pacific creates constant coordination between Seattle (PST/PDT) and ports in Busan, Tokyo, Shanghai, and Singapore (UTC +8:00 to +9:00), a difference of 15–17 hours that requires around-the-clock port operations.
Seattle observes the standard US DST schedule: clocks advance on the second Sunday in March and fall back on the first Sunday in November. Washington state has not moved to abolish DST despite periodic legislative discussions.
Seattle business hours run 9:00 AM to 6:00 PM PST/PDT, Monday to Friday. Tech companies often operate flexible hours.
