About these time zones
PDT: Pacific Daylight Time
Pacific Daylight Time is UTC−7.
California, Washington, Oregon and Nevada, plus British Columbia in Canada, from March to November. The rest of the year the zone is on PST.
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.
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.
