London to Hong Kong Time Converter
Hong Kong is 7 hours ahead of London while London is on daylight saving time (from late March to late October), and 8 hours ahead the rest of the year. Hong Kong doesn’t use daylight saving time, which is why the gap moves.
On Monday, October 19, Hong Kong is 7 hours ahead of London.
Heads-up: clocks in London go back on Sunday, October 25. After that, Hong Kong is 8 hours ahead of London.
Time zone rules checked October 2026. The converter runs on your device using its built-in time zone database, so it accounts for daylight saving time on any date you pick.

The best time for a call
If both sides keep roughly 9-to-5 hours, you get 1 hour hour of overlap on a normal weekday: 9:00 AM to 10:00 AM in London, which is 4:00 PM to 5:00 PM in Hong Kong.
When the gap is 8 hours, the overlap disappears entirely.
Hong Kong is on UTC+8 year round, the same as Singapore, Shanghai, Perth and Manila. That makes the gap eight hours in the UK winter and seven in summer.
As with most London–Asia routes, the overlap is the start of the London day and the end of the Hong Kong one: a 9 a.m. call in London is 5 p.m. in Hong Kong in winter and 4 p.m. in summer. Mainland China uses the same clock, so a call that includes Shanghai or Shenzhen fits the same slot.

Why the time difference changes
Hong Kong keeps the same time all year (UTC+8). London doesn’t: its clocks go forward on the last Sunday in March and back on the last Sunday in October. Every time London changes, the gap changes with it.
