8 AM GMT to Singapore: what to know
The London–Singapore gap is 8 hours in winter (GMT) and 7 hours in summer (BST). 8 AM GMT = 4 PM Singapore is one of the most practical windows for London–Singapore calls: London is starting the day, Singapore is in late afternoon with time to wrap up after the call.
As the UK day progresses, Singapore moves toward close of business and eventually evening. 9 AM GMT / 5 PM Singapore is the latest slot that keeps both cities in standard working hours. Later UK hours push Singapore into the evening. Use the London to Singapore planner for the live overlap window.
