Time Conversion Guide: HKT to BST

HKT runs on Hong Kong Time (HKT) at UTC+08:00. BST runs on British Summer Time (BST) at UTC+01:00. That puts HKT 7 hours behind BST — a difference of -7h at the current offsets.

In practice, when it is 9:00 AM in HKT it is 2:00 AM in BST. Midnight in HKT is 5:00 PM in BST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert HKT to BST time

  • Scheduling a call from HKT to BST: a 10:00 AM start in HKT lands at 3:00 AM in BST, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both HKT and BST are inside the 9-to-5 working day between 4:00 PM and 5:00 PM HKT time (9:00 AM–10:00 AM BST). That is roughly 1 hours of usable overlap.
  • Watching a live event or market open: HKT viewers need 2:00 AM in BST to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to HKT.
  • Always state the zone abbreviation, not just the hour. "3:00 PM HKT" is unambiguous; "3 PM" across a -7h gap is not.
  • Block 4:00 PM–5:00 PM HKT as the recurring meeting window if you work primarily from HKT and need BST colleagues present.

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 BST (British Summer Time)

British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.

Best time to call between HKT and BST

Both HKT and BST sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM HKT, which is 9:00 AM–10:00 AM BST. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

HKT and BST overlap for only 60 minutes (4:00 PM–5:00 PM HKT), so meetings have to be booked precisely.

HKT is 7 hours behind BST (HKT UTC+08:00 → BST UTC+01:00). The shared working window is 4:00 PM–5:00 PM HKT. Remember to re-check around daylight-saving transitions.
