Who‘s on PST Time? A Friendly Guide

Hey there! As a fellow tech enthusiast, I know time zones can be confusing. I put together this guide to help explain Pacific Standard Time (PST) in simple terms.

Living on the West Coast, I use Pacific Time every day without thinking much about it. But when coordinating with friends, colleagues and gamers from other time zones, PST suddenly becomes much more relevant!

So I wanted to help explain exactly which regions and major cities use Pacific Standard Time, how it fits in with the other North American time zones, and when you need to pay attention to PST in daily life.

What is Pacific Standard Time?

First, let‘s cover the basics.

Pacific Standard Time (PST) is the time zone along the West Coast of North America. It includes major cities like Los Angeles, San Diego, San Francisco, Seattle and Vancouver.

PST runs along the Pacific Ocean from Vancouver, Canada down to the Baja California peninsula in Mexico. It is 8 hours behind Coordinated Universal Time (UTC-08:00).

So when it is midnight in Los Angeles, it is 08:00 UTC.

Fun fact: Every 15° of longitude east or west equals an hour time zone difference. Since the Pacific Time zone is centered around 120°W longitude, it lands 8 hours behind the Prime Meridian.

During Daylight Saving Time from mid-March to early November, the zone shifts to Pacific Daylight Time (PDT) which is UTC-07:00.

Alright, now that we‘ve got the basics down, let‘s look at which states, cities and regions actually use PST.

Which States and Cities Use PST?

The U.S. states that fall completely within the Pacific Time Zone are California and Washington.

However, PST is also observed in parts of several other states and one Canadian province:

• Oregon
• Idaho
• Nevada
• Alaska
• British Columbia

And of course, the Mexican state of Baja California also follows Pacific Time.

According to the U.S. Census Bureau, some of the major metropolitan areas observing PST include:

• Los Angeles-Long Beach-Anaheim, CA (13.1 million)
• San Francisco-Oakland-Berkeley, CA (4.7 million)
• San Diego-Chula Vista-Carlsbad, CA (3.3 million)
• Seattle-Tacoma-Bellevue, WA (3.7 million)
• San Jose-Sunnyvale-Santa Clara, CA (1.9 million)
• Portland-Vancouver-Hillsboro, OR-WA (2.4 million)
• Sacramento-Roseville-Folsom, CA (2.3 million)
• Riverside-San Bernardino-Ontario, CA (4.5 million)

That‘s over 35 million people in PST metro areas just in the United States!

Clearly, this time zone covers some major population centers even if only two states fully observe it.

Not every PST zone city changes their clocks for Daylight Saving Time either. For example, Arizona and Hawaii both stay on standard time all year round.

How Far Does the PST Zone Extend?

Since I‘m a very visual person, maps help me wrap my head around time zones. Here‘s a map showing the extent of the Pacific Time Zone across North America:

You can see PST covers the entire West Coast region, from Mexico up to Canada‘s Vancouver Island. Then it stretches east across Washington, Oregon, Idaho, Nevada and the southern half of British Columbia in Canada.

An interesting outlier is Alaska which mostly observes its own Alaska Time Zone – even though geographically it lies within the PST longitudes. More on how Alaska fits in later!

How Pacific Time Fits with Other North American Zones

To understand PST, it helps to see how it fits in with the other major North American time zones. Moving east from the Pacific Time Zone, the zones are:

• Mountain Time – UTC-07:00 – (Arizona, parts of other states)
• Central Time – UTC-06:00 – (Midwest/Central states)
• Eastern Time – UTC-05:00 – (Northeastern states)

So Pacific Time is:

• 1 hour behind Mountain Time
• 2 hours behind Central Time
• 3 hours behind Eastern Time

For example, when it‘s 3pm in Los Angeles, it‘s:

• 2pm in Phoenix, Arizona (MST)
• 4pm in Chicago, Illinois (CST)
• 6pm in New York City, New York (EST)

That 3 hour gap between PST and EST can take some getting used to!

Here‘s a table summarizing the differences between time zones:

Time Zone	Offset from UTC	Offset from PST
Pacific Standard Time (PST)	UTC-08:00	–
Mountain Standard Time (MST)	UTC-07:00	+1 hour
Central Standard Time (CST)	UTC-06:00	+2 hours
Eastern Standard Time (EST)	UTC-05:00	+3 hours

Keep in mind that nearly all of the Mountain, Central and Eastern time zone states observe Daylight Saving Time as well.

So in summer, the zones shift to PDT, MDT, CDT and EDT respectively.

Fun Fact: Alaska‘s Unique Time Zone

I mentioned Alaska is a bit of an anomaly when it comes to U.S. time zones.

Even though Alaska geographically falls within the Pacific and Mountain time zones, most of the state actually observes the Alaska Time Zone which is centered around 150°W longitude. It is UTC-09:00, one hour behind Pacific Time.

Why does Alaska get its own time zone? Turns out it has to do with politics and commerce.

When Alaska first observed time zones in 1867, the territory chose to place its capital Juneau in the same zone as commerce hubs Anchorage and Fairbanks rather than follow geographical lines.

This placed most of populated Alaska into a unique offset from other West Coast cities. And the Alaska Time Zone was born!

Today, only a tiny unpopulated part of Alaska near the Canadian border actually observes Pacific Time.

Who Actually Refers to PST in Daily Life?

Since huge metro areas like LA and Silicon Valley run on Pacific Time, PST gets referenced a lot, even if you don‘t live there.

As a streaming and gaming nut, I often see video game releases, esports tournaments, Twitch streams and other events listed in PST time – even when hosted by East Coast companies.

Other common places PST gets used include:

• TV show times listed by networks like ABC, Fox, NBC
• Movie release dates and showtimes
• Tech product launches and update releases
• Flight schedules and airline booking
• Online meeting times across time zones
• Appointment booking apps and calendar software
• Weather forecasts and storm warnings

So even if you live in New York, you‘ll inevitably encounter many references to PST in everyday digital life and scheduling. It pays to learn the conversions!

How Far Ahead Is PST from Asia Time Zones?

As a night owl, I end up on video calls with teammates in India and China often. There can be a 12+ hour time difference!

Here‘s how far ahead major Asian time zones are from Pacific Standard Time:

• Tokyo, Japan (JST): +17 hours
• Shanghai, China (CST): +16 hours
• Mumbai, India (IST): +12.5 hours
• Seoul, South Korea (KST): +16 hours
• Singapore (SGT): +15 hours

That‘s a huge gap! No wonder it feels like the workday never ends when collaborating globally. 😅

Even cities on the opposite side of the globe like London (BST) are 8 hours ahead of PST.

What Are the Most Extreme Time Zones Compared to PST?

While Asia is far ahead of PST, there are some time zones even further ahead if you travel into the Pacific Ocean:

• The Chamorro Time Zone (ChST) of Guam is +10 hours ahead of Pacific Time at UTC+10:00.
• The Line Islands like Kiritimati in Kiribati are a massive +14 hours ahead at UTC+14:00. This is the furthest time zone ahead of UTC.

On the other side, time zones like Baker Island, US at UTC-12:00 are -20 hours behind PST!

That means there can be up to a 26 hour time difference between Earth‘s extreme time zones. Talk about time warp! ⏰

Converting Between PST and Other Time Zones

With so many time zones ahead and behind PST, converting can seem intimidating.

Luckily, the secret is simple math – just add or subtract the hour offset between zones.

Let‘s try some examples:

• It‘s 9am in New York City (EST). EST is 3 hours ahead of PST, so we subtract 3 hours:

  • 9am EST – 3 hours = 6am PST

• It‘s 2pm in Houston, Texas (CST). CST is 2 hours behind PST, so we add 2 hours:

  • 2pm CST + 2 hours = 4pm PST

See, not so bad!

There are also many handy online time converters that make time zone math easy:

• Time Zone Converter – My personal fave!
• Worldtime Buddy – Helpful for scheduling meetings
• Every Time Zone – Great map view

I always bookmark these sites for quick reference.
