PST and UTC on the World Map
The map below highlights the PST (Pacific Standard Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
PST – Pacific Standard Time
UTC-08:00Pacific Standard Time (PST) is the time zone for the US and Canadian Pacific coast, 8 hours behind UTC.
- •Silicon Valley and the world's biggest tech companies operate on Pacific Time.
- •The Hollywood film industry runs on PST/PDT.
- •PST is 3 hours behind EST, creating a significant business hours gap.
- •Vancouver, Canada's third-largest city, uses PST.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
Comparing Time Zones: PST and UTC
PST runs on Pacific Standard Time (PST) at UTC-08:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts PST 8 hours ahead of UTC — a difference of +8h at the current offsets.
In practice, when it is 9:00 AM in PST it is 5:00 PM in UTC. Midnight in PST is 8:00 AM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PST to UTC time
- Scheduling a call from PST to UTC: a 10:00 AM start in PST lands at 6:00 PM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: PST and UTC have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in UTC is 5:00 PM in PST.
- Watching a live event or market open: PST viewers need 5:00 PM in UTC to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to PST.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +8h gap is not.
- With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week UTC does.
About PST (Pacific Standard Time)
Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
Best time to call between PST and UTC
With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. UTC opens at 9:00 AM UTC, which is 5:00 PM in PST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
PST and UTC have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
PST is 8 hours ahead of UTC (PST UTC-08:00 → UTC UTC+00:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
