I believe the use of "PST" to mean "Pacific Time" has become so common in language that it's pretty much "official". If somebody says "PST" to you, 99% of the time they just mean "Pacific Time" in general as per current daylight savings time rules. Talking to a human you'll be fine saying "Pacific Time", "PT", or "PST" (which, again, has come to be interchangeable with "PT" although purists like myself believe otherwise :) ). In computing we tend to just represent times in UTC to avoid ambiguity. much of Arizona does not observe daylight savings time). Mountain Time, for example, is slightly more complicated than Pacific Time because it covers a larger area with more diverse daylight savings rules (e.g. California shares its time zone and DST schedule with bordering states Oregon and Nevada. Likewise, "I'll meet you in San Francisco Nov 3rd, 5:00 PM PT" means "on November 3rd, when clocks in San Francisco say 5:00 PM", which in that case would be 5:00 PM PST (UTC-8). Sunday, JFullscreen Time Zone Currently Being Used in California California Is in the Pacific Time Zone California uses Pacific Standard Time (PST) during standard time and Pacific Daylight Time (PDT) during Daylight Saving Time (DST). "I'll meet you in San Francisco Nov 1st, 5:00 PM PT" means "on November 1st, when clocks in San Francisco say 5:00 PM", which in that case would specifically be 5:00 PM PDT (UTC-7). Usually, then, when talking to humans (as opposed to computers) you'd use PT (or, colloquially, PST, even though it's arguably incorrect) to mean "whatever time it is in Pacific Time in whatever location we're talking about". This time zone converter lets you visually and very quickly convert PST to Los Angeles, California time and vice-versa. PT (or rarely, PDST): A vaguer concept taken to mean "whatever UTC offset is currently in effect in the Pacific Timezone, in the location given by context".PST: A fixed, standard time, always UTC-8.PDT: A fixed, standard time, always UTC-7.With that in mind, another way of viewing it is: This is all oversimplified, as daylight savings rules are different in different cities and countries. PT = Pacific Time = a general reference to the time zone, which alternates between PDT and PST depending on the time of year.Ĭolloquially, people seem to like using PST and PT interchangeably, and will still (IMO, incorrectly) refer to times as PST even when daylight savings time is in effect and Pacific Time is UTC-7.Īlso, colloquially, I have seen PDST sometimes used interchangeably with PT to refer to the timezone that alternates between PDT and PST. PST = Pacific Standard Time = fixed to UTC-8.PDT = Pacific Daylight Time = fixed to UTC-7.Even the easternmost tip of the state is still further west than Tijuana in Baja California.My understanding, and the way things are typically named at least in the context of computing (I'm a programmer by trade), has always been the following: It's worth noting that Yukon is in the far west of Canada. Also the Baja California, thus the Mexican peninsula belongs only with its northern half to the PST.Ĭanadian Yukon changed in the year 2020 from the PST to the "Mountain Time" (MST), to be one hour closer to the rest of the country. There, 2 time zones prevail within the same states. Your account will use this time zone if you didnt. This time zone is eight hours behind Coordinated Universal Time (UTC-8) and is used by millions of people every day. While the two US states of Washington and California are fully part of Pacific Time, this is no longer true for Alaska, Idaho, Nevada and Oregon. time zone for Google headquarters in Mountain View, California. What is the Time Zone Map Pst The Time Zone Map Pst refers to the Pacific Standard Time Zone, which covers much of the western United States, including California, Oregon, and Washington. Unification also tests the geographic extent of the Pacific time zone. In Mexico's Pacific Time area, these dates have only been in effect since 2010, though the rest of Mexico uses different dates for the remaining time zones. Compared to the previous arrangement, daylight saving time thus starts about two weeks earlier and ends one week earlier - so it's also 1 week longer. The Pacific Time Zone ( PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. On the first Sunday in November, it goes back one hour to standard time (PST). Changeover to a uniformed daylight saving time Since 2007, the changeover in the USA and Canada always takes place on the second Sunday in March to daylight saving time (PDT).
