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.

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

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).

Understanding the -16h Gap: AWST vs PST

AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. PST runs on Pacific Standard Time (PST) at UTC-08:00. That puts AWST 16 hours behind PST — a difference of -16h at the current offsets.

In practice, when it is 9:00 AM in AWST it is 5:00 PM in PST on the previous day. Midnight in AWST is 8:00 AM in PST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AWST to PST time

Scheduling a call from AWST to PST: a 10:00 AM start in AWST lands at 6:00 PM in PST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -16h gap: AWST and PST 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 PST is 5:00 PM in AWST.
Booking travel or deliveries: tracking PST local time against AWST keeps pickup windows and arrival estimates honest across the -16h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM AWST" is unambiguous; "3 PM" across a -16h gap is not.
With a -16h gap there is no shared 9-to-5 window, so alternate the early start: one week AWST takes the early slot, the next week PST does.

About AWST (Australian Western Standard Time)

Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.

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.

Best time to call between AWST and PST

With a -16h offset there is no overlap inside a normal 9 AM – 5 PM day. PST opens at 9:00 AM PST, which is 5:00 PM in AWST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

AWST and PST have no shared working hours because of the -16h gap. Teams need to alternate early starts or rely on asynchronous handovers.

AWST is 16 hours behind PST (AWST UTC+08:00 → PST UTC-08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
