What is the time difference between Mountain Standard Time (MST) and Pacific Standard Time (PST)?
PST is one hour ahead of MST
MST is one hour ahead of PST
MST and PST are the same
MST is two hours ahead of PST
Mountain Standard Time (MST) runs one hour ahead of Pacific Standard Time (PST). When it's noon in PST, it's 1:00 PM in MST. This consistent one-hour difference holds true during standard time periods. For more details, see .
If it's 3:00 PM PST, what time is it in MST?
4:00 PM
3:00 PM
2:00 PM
5:00 PM
Since MST is one hour ahead of PST, when it's 3:00 PM in Pacific Standard Time, it's 4:00 PM in Mountain Standard Time. This offset remains consistent during standard time. For more context, visit .
Which of these states is entirely within the Pacific Time Zone?
California
Colorado
Nevada
Arizona
California is the only state listed that lies entirely in the Pacific Time Zone. Nevada spans both Pacific and Mountain Time, Arizona is in Mountain Time, and Colorado is fully Mountain Time. For a full breakdown, see .
During Daylight Saving Time, Pacific Daylight Time (PDT) is UTC?7. What is the corresponding offset for Mountain Daylight Time (MDT)?
UTC?7
UTC?8
UTC?5
UTC?6
Mountain Daylight Time (MDT) runs one hour ahead of Pacific Daylight Time (PDT), so if PDT is UTC?7, then MDT is UTC?6. This daylight saving offset is observed after clocks spring forward. You can learn more at .
If a meeting is scheduled at 10:00 AM MDT, what time should a participant in Seattle (PDT) plan to join?
10:00 AM PDT
8:00 AM PDT
11:00 AM PDT
9:00 AM PDT
Mountain Daylight Time is one hour ahead of Pacific Daylight Time. Thus, a 10:00 AM MDT meeting corresponds to 9:00 AM PDT in Seattle. This applies during daylight saving months. For verification, see .
Arizona does not observe Daylight Saving Time. During DST, if it's 9:00 AM in Phoenix, what time is it in Los Angeles (PDT)?
8:00 AM PDT
9:00 AM PDT
10:00 AM PDT
7:00 AM PDT
Phoenix stays on Mountain Standard Time (UTC?7) year-round, matching Pacific Daylight Time (PDT) during daylight saving. Therefore, when it's 9:00 AM in Phoenix, it is also 9:00 AM in Los Angeles. More details at .
Denver is in Mountain Time. If UTC time is 18:00 during standard time, what local time is it in Denver (MST)?
11:00 AM
10:00 AM
12:00 PM
1:00 PM
Mountain Standard Time is UTC?7. Subtracting seven hours from 18:00 UTC results in 11:00 AM MST in Denver. This calculation holds during standard time. For confirmation, see .
Which of these cities switches to Mountain Daylight Time (MDT) on the second Sunday in March?
Phoenix
Anchorage
Los Angeles
Denver
Denver observes daylight saving time and moves from MST to MDT on the second Sunday in March each year. Los Angeles is in Pacific Time, Phoenix does not observe DST, and Anchorage follows Alaska Time. See for more.
A flight departs San Francisco (PST) at 8:00 AM PST and arrives in Calgary (MST) after a 3-hour flight. What local time is it upon arrival?
1:00 PM MST
10:00 AM MST
11:00 AM MST
12:00 PM MST
8:00 AM PST is 9:00 AM MST because MST is one hour ahead. A 3-hour flight adds three hours, making the local arrival time 12:00 PM MST. This applies during standard time. More details at .
During the week in November when clocks fall back, what happens to the time difference between Pacific Time and Mountain Time?
It remains one hour
It changes to two hours
It changes to zero hours
It depends on the day
When clocks fall back in autumn, both Pacific and Mountain zones revert one hour simultaneously on the same date. The one-hour difference between Pacific Time and Mountain Time remains constant. For further reading, see .
What is the UTC offset for Mountain Standard Time (MST)?
UTC?5
UTC?6
UTC?8
UTC?7
Mountain Standard Time is seven hours behind Coordinated Universal Time, with an offset of UTC?7. During standard time months, MST remains at this offset. See for details.
If it is 6:00 PM MDT in Albuquerque on July 1st, what is the corresponding UTC time?
00:00 UTC
23:00 UTC
01:00 UTC
12:00 UTC
Mountain Daylight Time is UTC?6. Adding six hours to 6:00 PM MDT gives 12:00 AM UTC (midnight). This conversion applies during daylight saving months. More info at .
Within Arizona, which region observes Daylight Saving Time and thus aligns with Mountain Daylight Time during the summer?
Grand Canyon National Park
Tucson metro area
Phoenix metro area
Navajo Nation
The Navajo Nation in northeastern Arizona observes Daylight Saving Time, switching to Mountain Daylight Time like other MDT regions. The rest of Arizona remains on MST year-round. Learn more at .
In Mexico, which state is in the Mountain Time Zone and observes DST on the same schedule as the US Southwest?
Baja California
Jalisco
Chihuahua
Sonora
Chihuahua is in the Mountain Time Zone and aligns its daylight saving schedule with the US Southwest. Sonora does not observe DST, Baja California follows Pacific Time rules, and Jalisco is in the Central Time Zone. For more, see .

Study Outcomes

  1. Understand time zone distinctions -

    Understand the key differences between Mountain Time vs Pacific Time Zone, including standard UTC offsets and daylight saving time practices.

  2. Identify daylight saving shifts -

    Identify when each zone begins and ends daylight saving time and how these shifts impact local time conversion.

  3. Calculate time conversions -

    Calculate accurate time differences between Pacific and Mountain zones to schedule events and appointments across regions.

  4. Apply scheduling scenarios -

    Apply your knowledge in real-world scenarios such as conference calls or travel planning to avoid time-related mix-ups.

  5. Recognize regional exceptions -

    Recognize specific areas that follow unique time-keeping rules, helping you navigate quirks beyond the standard mountain vs pacific time quiz questions.

Cheat Sheet

  1. Core Time Difference -

    Pacific Time is consistently one hour behind Mountain Time (PT = MT − 1). A handy mnemonic "PT Pressed Back" helps you recall that when it's 4 PM MT, it's 3 PM PT (Source: U.S. Department of Transportation).

  2. Daylight Saving Shifts -

    Both Pacific and Mountain Time zones observe Daylight Saving Time from the second Sunday in March to the first Sunday in November. Clocks "spring forward" by one hour at 2 AM local time in March and "fall back" at 2 AM in November, affecting your pacific vs mountain time quiz answers if you forget the dates (Source: National Institute of Standards and Technology).

  3. Arizona's DST Exception -

    Most of Arizona stays on Mountain Standard Time all year, so during DST it matches Pacific Time instead of shifting forward. Remember this quirk when tackling pacific time zone quiz questions about state-specific rules (Source: Arizona State Library).

  4. Geographic Boundaries -

    States like Idaho, Oregon and Nevada straddle both zones, and county lines often determine which time applies. Consult official state maps or the U.S. Geological Survey for exact boundaries before firing off answers in a mountain time vs pacific time zone challenge.

  5. Quick Conversion Formula -

    Use MT = PT + 1 and PT = MT − 1 as your go-to conversion equations when faced with time zone quiz online questions. For 24-hour times simply add or subtract one hour and wrap around midnight (e.g., 0:30 PT = 1:30 MT) to stay confident during any pacific time questions.
