HKT vs GMT Time Difference
See the live time difference between Hong Kong Time and Greenwich Mean Time, including DST changes and the best hours to schedule meetings.
Current 8-Hour Difference
Hong Kong Time is UTC+8, while Greenwich Mean Time is UTC+0, so the standard time difference is 8 hours. Use this page to see the current offset and compare both zones hour by hour.
DST Effects Explained
Hong Kong Time does not observe daylight saving time, but regions using Greenwich Mean Time may switch to British Summer Time in summer. The comparison updates automatically to reflect DST changes and IANA timezone database rules.

How to Find the Time Difference Between HKT and GMT
Open the HKT vs GMT converter: Go to
https://www.xconvert.com/time-converter/hkt-vs-gmtto see Hong Kong Time and Greenwich Mean Time laid out on the visual comparison grid. This page is useful when you are scheduling a call between Hong Kong and the United Kingdom, coordinating with finance teams that work on London hours, or planning support coverage between Asia and West Africa.Add comparison cities with the + Add City button: Click + Add City and search for cities that matter to your schedule, such as Hong Kong, London, or Accra. This helps if you work with trading, logistics, legal, or multinational operations, because GMT is used across countries including Ghana, Senegal, Iceland, and the United Kingdom, while HKT is used in Hong Kong.
Drag across the grid to select a meeting window: Click Select if needed, then drag across the colored timeline to highlight a time range in purple, using the left and right handles to fine-tune it. For example, if you drag from 9:00 to 12:00 HKT, the grid shows that this corresponds to 1:00 to 4:00 GMT, which is useful for confirming whether a Hong Kong morning meeting fits a London or Accra workday.
Export and share the chosen time range: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is practical for sending a confirmed cross-border meeting to a remote team so colleagues in Hong Kong and GMT locations receive the event in their own local calendar context without manual conversion mistakes.
HKT vs GMT Offset Explained
Hong Kong Time (HKT) is UTC+8, and Greenwich Mean Time (GMT) is UTC+0. That means GMT is 8 hours behind HKT, or viewed the other way, HKT is 8 hours ahead of GMT. In practical scheduling terms, when it is 9:00 in HKT, it is 1:00 in GMT, and when it is 18:00 in HKT, it is 10:00 in GMT.
This gap is especially important for business calls because a standard Hong Kong workday begins much earlier than a GMT-based workday. The examples make that clear: 12:00 HKT = 4:00 GMT and 15:00 HKT = 7:00 GMT, so many Hong Kong afternoon meetings still fall in the early morning for teams working on GMT. That matters for sectors such as banking, shipping, sourcing, legal services, and distributed customer support where Hong Kong often coordinates with London-linked or West African markets.
HKT does not observe daylight saving time, so Hong Kong stays on the same offset year-round. GMT is a standard-time abbreviation, and its daylight saving counterpart is BST, which means users comparing Hong Kong with the United Kingdom need to pay attention to whether they specifically mean GMT or British Summer Time. If your meeting is tied to GMT itself, the difference remains the same as shown here: 8 hours.
GMT is used across a wide geographic set of countries and territories, including Burkina Faso, Gambia, Ghana, Guernsey, Guinea, Guinea-Bissau, Iceland, Ireland, Isle of Man, Ivory Coast, Jersey, Liberia, Mali, Mauritania, Saint Helena, Sao Tome and Principe, Senegal, Sierra Leone, Togo, and the United Kingdom. HKT is used in Hong Kong, making this comparison common for firms that manage Asia-Europe reporting cycles, shipping documentation, international procurement, and media or technology teams working across both regions.
Practical HKT to GMT Scheduling Examples
The most useful way to compare these time zones is to anchor your planning around fixed examples. If your Hong Kong office proposes a 9:00 HKT kickoff, that is 1:00 GMT, which is usually outside normal office hours in many GMT locations. A 12:00 HKT meeting becomes 4:00 GMT, while 15:00 HKT becomes 7:00 GMT, often making it easier for early-start teams in GMT regions to join.
Late-day coordination in Hong Kong can still work for same-day communication with GMT teams. For example, 18:00 HKT = 10:00 GMT, which can be a practical overlap for client calls, operations reviews, or handoffs between an Asia-based team and colleagues in London, Accra, or Dakar working on GMT. This pattern is common in trade, freight forwarding, compliance reviews, and multinational project management where documents are prepared in Asia and reviewed in Europe or Africa later the same day.
Because the difference is large and one-directional, HKT mornings usually map to very early GMT hours, while HKT evenings align more closely with the GMT workday. That makes the visual grid especially useful when choosing a slot that avoids forcing one side into night hours. Teams handling recurring meetings can use the purple selection range and export tools to lock in a repeatable overlap window and reduce back-and-forth scheduling.
Frequently Asked Questions
What is the time difference between HKT and GMT?
The time difference is 8 hours. GMT is 8 hours behind HKT, which also means HKT is 8 hours ahead of GMT. A simple example is 9:00 HKT = 1:00 GMT.
Is Hong Kong Time always 8 hours ahead of Greenwich Mean Time?
Yes, for this comparison, HKT is 8 hours ahead of GMT. HKT does not observe DST, and GMT is the standard-time reference at UTC+0, so the relationship shown here remains 8 hours when comparing HKT directly with GMT.
How do I convert 9 AM, 12 PM, or 3 PM HKT to GMT?
Use the fixed examples shown on the page. 9:00 HKT = 1:00 GMT, 12:00 HKT = 4:00 GMT, and 15:00 HKT = 7:00 GMT. These examples are useful for planning morning, midday, and afternoon calls from Hong Kong with teams working on GMT.
What is 6 PM HKT in GMT?
18:00 HKT = 10:00 GMT. This is one of the more practical overlap points for same-day business communication, because a late Hong Kong meeting can still land in the morning for GMT-based teams.
Does HKT have daylight saving time?
No, HKT does not observe DST. That means Hong Kong Time stays at UTC+8 throughout the year, which helps keep scheduling consistent for teams that regularly work with Hong Kong.
Is GMT the same as UK summer time?
No. GMT is the standard-time abbreviation, while BST is its daylight saving counterpart. This distinction matters if you are scheduling with the United Kingdom, because a meeting labeled GMT is not the same as one labeled BST.
Which countries use GMT?
GMT is used in Burkina Faso, Gambia, Ghana, Guernsey, Guinea, Guinea-Bissau, Iceland, Ireland, Isle of Man, Ivory Coast, Jersey, Liberia, Mali, Mauritania, Saint Helena, Sao Tome and Principe, Senegal, Sierra Leone, Togo, and the United Kingdom. This broad usage makes HKT-to-GMT conversion relevant for trade, government coordination, education, aviation planning, and multinational business communication.
When is the best time to schedule a call between Hong Kong and GMT?
The most workable overlap usually comes later in the Hong Kong day, because GMT is 8 hours behind. The examples show why: 15:00 HKT = 7:00 GMT and 18:00 HKT = 10:00 GMT, so Hong Kong afternoons and early evenings are generally more realistic than Hong Kong mornings for live meetings with GMT-based teams.
