seattime

Seattime is an informal term used to denote the local time in Seattle, Washington. In contexts such as scheduling, travel planning, software localization, or internal calendars, seattime serves as shorthand for Pacific Time as observed in Seattle. It is not an official time standard or time zone designation, but it is commonly understood in situations where reference to Seattle’s local time is needed.

Seattle lies in the Pacific Time Zone. During standard time, seattime corresponds to UTC-8; during daylight saving time, it corresponds to UTC-7. Daylight saving time in Seattle begins on the second Sunday in March and ends on the first Sunday in November, during which seattime is often labeled as Pacific Daylight Time (PDT).

In technology and communications, seattime may appear as a locale setting or display label for services or users based in Seattle. When scheduling across regions, it is important to translate seattime into the target time zone, accounting for DST changes. To avoid ambiguity, users and systems commonly employ explicit time zone abbreviations or offsets (for example, PDT UTC-7 or PST UTC-8) instead of relying on a general reference to seattime.

Limitations exist because seattime is an informal term and has no official status in timekeeping. It is most frequently encountered in casual conversation, consumer apps, or internal corporate calendars where the need is to reference Seattle’s local time without specifying a time zone.
