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.
