UTC and HKT on the World Map
The map below highlights the UTC (Coordinated Universal Time) and HKT (Hong Kong Time) timezone regions across the globe.
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.
HKT – Hong Kong Time
UTC+08:00Hong Kong Time (HKT, UTC+08:00) is the time zone for Hong Kong, 8 hours ahead of UTC.
- •Hong Kong does not observe daylight saving time and has kept UTC+08:00 since 1979.
- •HKT shares its offset with China Standard Time, Singapore Time and Philippine Time.
- •The Hong Kong Stock Exchange opens at 09:30 HKT.
- •Hong Kong Time does not change with the seasons, so its gap to other zones is fixed.
Everything You Need to Know About UTC and HKT Time
UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. HKT runs on Hong Kong Time (HKT) at UTC+08:00. That puts UTC 8 hours ahead of HKT — a difference of +8h at the current offsets.
In practice, when it is 9:00 AM in UTC it is 5:00 PM in HKT. Midnight in UTC is 8:00 AM in HKT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert UTC to HKT time
- Scheduling a call from UTC to HKT: a 10:00 AM start in UTC lands at 6:00 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +8h gap: UTC 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 5:00 PM in UTC.
- Coordinating a UTC-based team with HKT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM UTC" 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 UTC takes the early slot, the next week HKT does.
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.
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 UTC and HKT
With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. HKT opens at 9:00 AM HKT, which is 5:00 PM in UTC, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
UTC and HKT have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
UTC is 8 hours ahead of HKT (UTC UTC+00:00 → 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.
