Heads up: only one of these cities has an upcoming daylight-saving change, so the gap between them will shift. Any recurring meeting will move by an hour for one side unless you re-check it after that date.
Best time to call Singapore from London
Singapore is 7 hours ahead of London. Calling Singapore from London works best between 09:00–10:00 London time, which lands at 16:00–17:00 for Singapore. The shared window opens in the London morning, which is the easier half of the day to protect.
There are only 1 hour where both cities are working, so the window is effectively one short call. Booking anything longer means someone stays late.
Avoid the first and last fifteen minutes of that range. Those edges are where one side is either still settling in or already packing up, and a call that runs five minutes over pushes someone past the end of their day.

Cross-timezone workday overlap and collaboration
With so little shared time, London and Singapore work best as an asynchronous pair with one synchronous exception. Write decisions down as they are made rather than saving them for a call, because the next chance to talk is a day away.
Treat the gap as a handoff rather than a delay. Whoever finishes first should leave the next step written down and unambiguous; 7 hours later the other side picks it up without needing to ask a question that would cost another full day.
Watch for fatigue on recurring meetings. A weekly call that sits at the very edge of someone's evening is tolerable once and corrosive after a month. If the only workable slot is uncomfortable for one side, rotate it, or accept that the meeting should be a document instead.
Practical rules for this pairing
- Book recurring meetings inside 09:00–10:00 London time and leave the rest of the day for focused work.
- Keep the first hour after Singapore comes online free of meetings, so anything blocking overnight gets picked up immediately.
- Do not stack two meetings in the window — there is not room, and the second will overrun into someone's evening.
Frequently asked questions (London & Singapore)
What is the current time difference between London and Singapore?
Singapore is 7 hours ahead of London. That gap is calculated from the live IANA time zone database, so it already accounts for whichever daylight-saving rules are in force today rather than assuming a fixed offset.
What is the best window for a one-hour team sync between London and Singapore?
Schedule it inside 09:00–10:00 London time, which is 16:00–17:00 in Singapore. That range is 1 hour long, so a one-hour meeting fits but leaves little margin.
Do London and Singapore change their clocks on the same date?
No. London changes its clocks on Sun, Oct 25, while Singapore has no upcoming change. The gap between the two cities will shift by 60 minutes on that date, so any recurring meeting will move relative to one side unless you re-check it.
How many hours do London and Singapore actually share in a working day?
Comparing a standard 9:00–17:00 day in each city gives 1 hour of shared working time. Widening either side's hours, or adding a split evening shift, increases it.
