PST vs MST: what is the difference?

Mountain Time (MST/MDT) is typically 1 hour ahead of Pacific Time (PST/PDT). When it is 9:00 AM in Los Angeles or Seattle, it is usually 10:00 AM in Denver or Phoenix*. Most of the Mountain West shifts with Pacific for daylight saving; Arizona (most of the state) stays on MST year-round, which can change the gap in summer.

Common anchors: Los Angeles, San Francisco, Seattle, and Vancouver (Pacific) ↔ Denver, Salt Lake City, Albuquerque, and Calgary (Mountain).

A 9:00 AM–5:00 PM Pacific workday overlaps about 10:00 AM–6:00 PM Mountain — still comfortable for West Coast ↔ Rockies collaboration.
