About MST to PDT Conversion

Converting time between MST and PST requires understanding their time zone offsets and any daylight saving time adjustments. MST (MST) operates at UTC-7, while PST (PDT) is set to UTC-8. This means PST is 1 hour behind MST. For example, when it's 4:59 PM MST on January 14, 2026, it's 3:59 PM PDT in PST. 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 PST for any time in MST, whether you're scheduling meetings, planning travel, or coordinating with teams across different time zones.
