Hong Kong is 6 hours ahead of Stockholm
Best overlap: 8:00 AM to 12:00 PM in Stockholm is 2:00 PM to 6:00 PM in Hong Kong.
Your window to reach both cities is 8:00 AM to 12:00 PM in Stockholm, which converts to 2:00 PM to 6:00 PM in Hong Kong. Hong Kong is 6 hours ahead of Stockholm, leaving about 4 hours of shared hours — plan recurring calls early in that window to leave buffer. Note the seasonal wrinkle: when Stockholm is on daylight saving and Hong Kong isn't, the gap between them grows or shrinks by an hour.
