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).

Everything You Need to Know About PDT and HKT Time

PDT runs on Pacific Daylight Time (PDT) at UTC-07:00. HKT runs on Hong Kong Time (HKT) at UTC+08:00. That puts PDT 15 hours ahead of HKT — a difference of +15h at the current offsets.

In practice, when it is 9:00 AM in PDT it is 12:00 AM in HKT on the next day. Midnight in PDT is 3:00 PM in HKT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PDT to HKT time

Scheduling a call from PDT to HKT: a 10:00 AM start in PDT lands at 1:00 AM in HKT the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +15h gap: PDT and HKT 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 HKT is 12:00 AM in PDT.
Booking travel or deliveries: tracking HKT local time against PDT keeps pickup windows and arrival estimates honest across the +15h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM PDT" is unambiguous; "3 PM" across a +15h gap is not.
With a +15h gap there is no shared 9-to-5 window, so alternate the early start: one week PDT takes the early slot, the next week HKT does.

About PDT (Pacific Daylight Time)

Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.

About HKT (Hong Kong Time)

Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.

Best time to call between PDT and HKT

With a +15h offset there is no overlap inside a normal 9 AM – 5 PM day. HKT opens at 9:00 AM HKT, which is 12:00 AM in PDT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

PDT and HKT have no shared working hours because of the +15h gap. Teams need to alternate early starts or rely on asynchronous handovers.

PDT is 15 hours ahead of HKT (PDT UTC-07:00 → HKT 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.
