Mountain Time = MT = either MST or MDT, depending on Daylight Saving Time rules.

Mountain Daylight Time = MDT = UTC -6 hours.

Mountain Standard Time = MST = UTC -7 hours, regardless of the date.

Pacific Time = PT = either PST or PDT, depending on Daylight Saving Time rules.

Pacific Daylight Time = PDT = UTC -7 hours.

Pacific Standard Time = PST = UTC -8 hours, regardless of the date.

For residents of states that observe Daylight Saving Time, omit “standard” or “daylight”. For Arizona residents, that means communicating Pacific Time, PT, during the spring/summer months and Mountain Time, during the fall/winter months. The solution was incredibly simple, for people in places that observe Daylight Saving Time, simply omit the words “standard” or “daylight” from your time zone vocabulary. The biggest challenge was around the use of the term Mountain Standard Time and its abbreviation, MST, when the person really meant to communicate Mountain Daylight Time, MDT. Quickly convert Pacific Standard Time (PST) to Greenwich Mean Time (GMT) accurately using our converter and conversion table. This caused a lot of confusion communicating meetings times, especially in the weeks leading up to their clocks changing in the spring or in the fall. Mexico City, Mexico time is 2 hours ahead of PST.

and done PST stands for Pacific Standard Time. Simply mouse over the colored hour-tiles and glance at the hours selected by the column.

You see Phoenix follows Mountain Standard Time, MST (UTC -7), all year round while Denver switches between Mountain Standard Time, MST (UTC -7), and Mountain Daylight Time, MDT (UTC -6), depending on the season. This time zone converter lets you visually and very quickly convert PST to Mexico City, Mexico time and vice-versa.

The issue became very apparent to me while working with a team that was split between Phoenix & Denver. Unfortunately, this seems to really confuse people in places that change their clocks depending on the time of year. Instead, we keep our clocks set to seven hours behind Coordinated Universal Time, UTC, 365.256 days per year. The State of Arizona, excluding the Navajo Nation, is one of the few places in the United States that does not intentionally move the hour hand of our clocks forward in the spring and back in the fall. Daylight saving is not observed in Queensland, Western Australia or the Northern Territory.As a lifelong resident of Arizona, one might think that I have been sheltered to the silliness of Daylight Saving Time, DST.
