Time in Tri-Cities, United States

Time zone: PDT (UTC/GMT -07:00) — America/Los_Angeles

If you need the offset: Tri-Cities is on PDT, 7 hours behind UTC, i.e. UTC-07:00. The matching IANA zone is America/Los_Angeles.

Expect a clock change on Sunday, 01 November 2026: Tri-Cities switches to PST, moving back by 1 hour. Until that date the UTC-07:00 offset above holds.

Across United States there are 10 distinct time zones among these 419 cities, so "local time" there depends entirely on which city you mean.

Population: about 244,036 — 57th largest of the 212 United States cities indexed here.

Current gap between Tri-Cities and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Assuming a 09:00–17:00 day at both ends, these windows (in Tri-Cities local time) fall inside working hours for both cities.

No shared working window exists with London, Paris, Dubai or Mumbai, so those calls have to sit outside somebody's normal hours.

No difference at all from Tri-Cities: the cities below share the America/Los_Angeles zone.
