Convert HKT to GMT

Hong Kong Time (HKT) to Greenwich Mean Time (GMT)

The Hong Kong-London finance axis is one of the world's busiest, connecting two major stock exchanges and banking hubs. The 8-hour gap means only a narrow morning-afternoon overlap. BST narrows it to 7 hours from late March to late October, which can make a meaningful difference for scheduling.

Scheduling Tips

  • Schedule critical syncs at 8:00-9:00 AM GMT / 4:00-5:00 PM HKT to catch both teams during working hours.
  • During BST (late March to late October), the window expands -- 8:00-10:00 AM BST / 3:00-5:00 PM HKT gives you a full 2 hours.
  • Avoid scheduling past 10:00 AM GMT as that pushes to 6:00 PM HKT and into personal time.
  • For finance teams tracking market handoffs, the HKEX close (4:00 PM HKT) aligns with 8:00 AM GMT -- use this natural pivot point for cross-market briefings.

Frequently Asked Questions

What is the time difference between HKT and GMT?
HKT (Hong Kong Time, UTC+8) is 8 hours ahead of GMT (UTC+0). When it is 4:00 PM in Hong Kong, it is 8:00 AM in London. During British Summer Time (late March to late October), the gap narrows to 7 hours.
Does the HKT-GMT offset change during the year?
Only on the UK side. Hong Kong does not observe DST. When the UK switches to BST (UTC+1) from late March to late October, the difference drops from 8 to 7 hours, improving the overlap window.
What time is 9 AM GMT in Hong Kong?
9:00 AM GMT is 5:00 PM HKT. During BST (summer), 9:00 AM BST is 4:00 PM HKT. UK mornings catch the final hours of the Hong Kong business day.
What is the best meeting time for Hong Kong and London?
The optimal window is 8:00-9:00 AM GMT / 4:00-5:00 PM HKT. London opens for business just as Hong Kong's workday is winding down. During BST, this extends to 8:00-10:00 AM BST / 3:00-5:00 PM HKT.
