Convert time from GMT to HKT. Enter any time to see the equivalent HKT time, compare current GMT and HKT times side by side, and find overlapping business hours for calls and meetings.

Converting between Greenwich Mean Time and Hong Kong Time means accounting for a 8 hours gap — here's how to do it in under 10 seconds with no sign-up.
Pick the date and time in Greenwich Mean Time (UTC +0) that you want to convert. Hit "Now" to load the current gmt time instantly, or use "+1h" to step forward and compare.
The equivalent Hong Kong Time (UTC +8) time appears immediately. Since hkt is 8 hours ahead of gmt, most daytime conversions stay on the same calendar day.
Click "Copy Time" to grab the hkt result for your calendar or message. Use "+1d" to check how the conversion shifts across dates — helpful for scheduling recurring United Kingdom–Hong Kong calls.
When someone in United Kingdom suggests 9:00 AM gmt, that's 5:00 PM hkt. This converter shows the overlap so both sides agree on one slot — no back-and-forth.
Late-night gmt times can land on a different date in hkt because of the 8 hours offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.
Daylight Saving adjustments can widen or narrow the gmt–hkt gap by an hour. During transition weeks many people get it wrong. This converter pulls the current UTC offsets automatically, so the result is right even on the changeover day.
Product launches, sports matches, and webinars are often announced in gmt. Convert the event time to hkt so you know exactly when to tune in — with a 8 hours difference, a morning event in United Kingdom falls during work hours in Hong Kong.
