Understanding 5:00 PM PST in MST

When it is 5:00 PM in Pacific Standard Time (PST), it is 6:00 PM in Mountain Standard Time (MST). This conversion accounts for the 1-hour forward offset between these two time zones. The result is calculated by adding 1 hours to the source time.

Los Angeles and Denver are among the most connected cities for business travel and remote collaboration. Knowing the exact time difference helps professionals plan meetings, coordinate project deadlines, and schedule deliveries without confusion or costly errors.

PST is also known as Pacific Time, PT, West Coast time, LA time, California time, while MST is referred to as Mountain Time, MT, Arizona time, Denver time. Whether you searched for Pacific Time to Mountain Time or PST to MST, the answer is the same.

Daylight Saving Time Impact

This conversion assumes the standard UTC offsets for PST (UTC-8) and MST (UTC-7). During daylight saving transitions — typically in March and November for US zones, or March and October for European zones — the offset between these time zones may shift by one hour.

For example, when the US springs forward in March, EDT replaces EST (shifting from UTC-5 to UTC-4), while CDT replaces CST (UTC-6 to UTC-5). If only one of the two zones transitions on a given date, the gap temporarily changes. Always double-check during transition weeks to avoid arriving an hour early or late.
