MST to PST converter

MST to PST quick reference

MST or MDT, PST or PDT? Daylight saving explained

MST (UTC−7) is the winter name and MDT (UTC−6) the summer name. This page uses Denver time, which changes its clocks. Most of Arizona (Phoenix) stays on MST all year, so in summer Phoenix is an hour behind Denver.

PST (UTC−8) is the winter name and PDT (UTC−7) the summer name. People usually write “PST” all year and mean local Pacific time (Los Angeles, San Francisco, Seattle), so MeetETA reads it that way and handles daylight saving for you.

Right now Denver is on MDT, UTC−6 and Los Angeles is on PDT, UTC−7 (the clocks at the top of the page always show the live values).
