About these time zones
MST: Mountain Standard Time
Mountain Standard Time is UTC−7. MST is also used for Malaysia Standard Time (UTC+8). This page converts US Mountain Time.
Colorado, Utah, New Mexico, Wyoming, Montana and southern Idaho, plus Alberta in Canada. Most of Arizona stays on MST all year (the Navajo Nation follows daylight saving time). MT is the short form for the whole zone.
Most places on Mountain Time are on MDT (UTC−6) right now, not MST. People still say "MST" all year, so the times on this page follow the clocks and show MDT until 1 November 2026.
PST: Pacific Standard Time
Pacific Standard Time is UTC−8. PST is also used for Philippine Standard Time (UTC+8) and sometimes for Pakistan Standard Time (UTC+5). This page converts US Pacific Time.
California, Washington, Oregon and Nevada, plus British Columbia in Canada and Baja California in Mexico. PT is the short form people use for the whole zone.
Most places on Pacific Time are on PDT (UTC−7) right now, not PST. People still say "PST" all year, so the times on this page follow the clocks and show PDT until 1 November 2026.
How the difference changes
Both zones change their clocks on the same dates (next on 1 November 2026), so the difference stays 1 hour all year.
