About PST to MST Conversion

Converting time between PST and MST requires understanding their time zone offsets and any daylight saving time adjustments. PST (PST) operates at UTC-8, while MST (MST) is set to UTC-7. This means MST is 1 hour ahead PST. For example, when it's 6:11 PM PST on February 3, 2026, it's 7:11 PM MST in MST. America/Los_Angeles observes daylight saving time, switching between PST (UTC-8) and PDT (UTC-7), while America/Phoenix does not observe daylight saving time. Use this converter to quickly find the equivalent time in MST for any time in PST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
