Why people convert London to HKT time

  • Scheduling a call from London to HKT: a 10:00 AM start in London lands at 5:00 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both London and HKT are inside the 9-to-5 working day between 9:00 AM and 10:00 AM BST time (4:00 PM–5:00 PM HKT). That is roughly 1 hours of usable overlap.
  • Coordinating a London-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 BST" is unambiguous; "3 PM" across a +7h gap is not.
  • Block 9:00 AM–10:00 AM BST as the recurring meeting window if you work primarily from London and need HKT colleagues present.
  • London: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +7h gap.

About GMT (Greenwich Mean Time)

Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

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.

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

Business hours overlap

London and HKT overlap for only 60 minutes (9:00 AM–10:00 AM BST), so meetings have to be booked precisely.

London is 7 hours ahead of HKT (BST UTC+01:00 → HKT UTC+08:00). The shared working window is 9:00 AM–10:00 AM BST. Remember to re-check around daylight-saving transitions.
