HKT and UTC on the World Map
The map below highlights the HKT (Hong Kong Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
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.
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.
Everything You Need to Know About HKT and UTC Time
HKT runs on Hong Kong Time (HKT) at UTC+08:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts HKT 8 hours behind UTC — a difference of -8h at the current offsets.
In practice, when it is 9:00 AM in HKT it is 1:00 AM in UTC. Midnight in HKT is 4:00 PM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert HKT to UTC time
- Scheduling a call from HKT to UTC: a 10:00 AM start in HKT lands at 2:00 AM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: HKT 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 1:00 AM in HKT.
- Keeping family and friends in sync: knowing that 8:00 PM in HKT is 12:00 PM in UTC makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM HKT" 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 HKT takes the early slot, the next week UTC does.
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.
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 HKT 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 1:00 AM in HKT, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
HKT and UTC have no shared working hours because of the -8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
HKT is 8 hours behind UTC (HKT 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.
