London to Singapore Time Converter
Singapore is 7 hours ahead of London while London is on daylight saving time (from late March to late October), and 8 hours ahead the rest of the year. Singapore doesn’t use daylight saving time, which is why the gap moves.
On Monday, October 19, Singapore is 7 hours ahead of London.
Heads-up: clocks in London go back on Sunday, October 25. After that, Singapore is 8 hours ahead of London.
Time zone rules checked October 2026. The converter runs on your device using its built-in time zone database, so it accounts for daylight saving time on any date you pick.

The best time for a call
If both sides keep roughly 9-to-5 hours, you get 1 hour hour of overlap on a normal weekday: 9:00 AM to 10:00 AM in London, which is 4:00 PM to 5:00 PM in Singapore.
When the gap is 8 hours, the overlap disappears entirely.
Singapore doesn’t change its clocks, so the gap is eight hours in the UK winter and seven during British Summer Time. In winter the working days barely touch: 9 a.m. in London is 5 p.m. in Singapore. The summer is kinder, giving about an hour at the start of the London day.
The London morning standup is the meeting Singapore colleagues can actually join. Anything after lunch in London is mid-evening there.

Why the time difference changes
Singapore keeps the same time all year (UTC+8). London doesn’t: its clocks go forward on the last Sunday in March and back on the last Sunday in October. Every time London changes, the gap changes with it.
