Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Q: What is UTC?

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Key Facts about PST

•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.

Daylight Saving:Yes – switches to PDT

Key Facts about UTC

•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.

Daylight Saving:No – UTC+00:00 year-round

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.
