MDT to PST Time Converter

PST is 1 hour behind MDT. MDT is UTC-6:00, and The US West Coast is currently on PDT (UTC-7:00).

Worth knowing right now. The US West Coast is currently on PDT, not PST, because daylight saving is in effect. The 1 hour above is the gap between those two regions today, which is almost certainly what you want. Taken strictly as written, MDT to PST is 2 hours.

What MDT and PST Actually Are

MDT — Mountain Daylight Time

Denver, Salt Lake City, Calgary, Edmonton. Standing at UTC-6:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to MST.

Because Arizona does not follow it, MDT is the half of the year when Phoenix and Denver read the same clock despite being in different zones.

PST — Pacific Standard Time

Los Angeles, San Francisco, Seattle, Las Vegas, Vancouver. Standing at UTC-8:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to PST. The Philippines occasionally uses PST for Philippine Standard Time (UTC+8); PHT is the clearer label for that.

California voted in 2018 to move to permanent daylight time, but the change needs an act of Congress and has never happened, so PST is still the winter standard.

What This Means in Practice

Both sides change clocks, on different dates

Both regions observe daylight saving but do not switch on the same day, so for a week or two each spring and fall the gap between them is an hour different from the rest of the year. Those short windows are where recurring invitations quietly break.

Close enough to share a working day

At only 1 hour apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
