BST: British Time
--:--:--
On January 15, 2026, HKT is 8 hours ahead of BST. On July 15 it is 7 hours ahead of BST.
These are dated examples. Select your actual date below: regions can change clocks on different dates, so the gap between the examples may differ.
The United Kingdom uses GMT in winter and BST (British Summer Time) in summer. BST also abbreviates Bangladesh Standard Time (UTC+6).
One instant, two local clocks
Both lanes show the same instant. Local dates, daylight, and offsets come from each IANA zone on the selected date, so daylight saving changes are included.

This table uses January 15 and July 15, 2026, at noon UTC. These are sample dates, not season-wide rules. Northern and southern regions follow different schedules, and transition weeks can have another gap. Use the date control above for the day you are planning.

The examples assume 9 AM to 5 PM on a working day in both places. They do not check weekends, local holidays, or individual schedules.
Standard business hours (9:00 AM to 5:00 PM) do not overlap on January 15: daytime in British Time falls outside the working day in Hong Kong Time, so one side needs an early morning or late evening.
On July 15 the overlap runs 9:00 AM to 10:00 AM in BST (4:00 PM to 5:00 PM in HKT).
Offsets are computed from the IANA time zone database for January 15 and July 15, 2026. BST here means British Time (United Kingdom); HKT means Hong Kong Time (Hong Kong).
