When daylight saving changes the gap
2026
Mountain Time (US) is 1 hour ahead of Pacific Time (US) all year.
Pacific Time (US) moves its clocks forward on March 8 (2:00 AM becomes 3:00 AM) and back on November 1 (2:00 AM becomes 1:00 AM). Mountain Time (US) moves its clocks forward on March 8 (2:00 AM becomes 3:00 AM) and back on November 1 (2:00 AM becomes 1:00 AM).
Both switch at 2:00 AM local time, which is a different moment in each zone, so for about an hour on March 8 and November 1 the gap is briefly different.

What PST and MST mean here
PST means US Pacific Time: Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver. That's PST (UTC−8) in winter and PDT (UTC−7) from March 8 to November 1, 2026. The Philippines also uses "PST" for Philippine Standard Time (UTC+8); for that, search for Manila.
MST means US Mountain Time as kept in Denver, Salt Lake City, Albuquerque and Calgary: MST (UTC−7) in winter and MDT (UTC−6) from March 8 to November 1, 2026. Arizona is the exception: most of the state stays on MST all year, so in summer Phoenix shows the same time as Los Angeles, not Denver.
