London to Singapore Time

London to Singapore conversion chart

Every full hour of Wednesday, October 14, 2026 in London, and the time in Singapore. Pick another date in the converter and the chart follows.

Daylight saving time in London and Singapore

• London: UK time, GMT (UTC+0) in winter and BST (UTC+1) in summer. Clocks go forward at 1:00 AM on the last Sunday in March and back at 2:00 AM on the last Sunday in October, the dates the UK government publishes.
• Singapore: Singapore Time, SGT (UTC+8), with no clock changes: Singapore has no daylight saving time.

Only London changes its clocks: on March 29 and October 25 in 2026, and on March 28 and October 31 in 2027. Singapore stays on SGT (UTC+8) all year. Once London switches on March 29, Singapore is 7 hours ahead of London, until the October 25 switch puts Singapore back at 8 hours ahead.

Singapore stands still and London moves twice a year, so the gap follows London. With BST in force, Singapore is 7 hours ahead of London. With GMT in force, Singapore is 8 hours ahead of London. The highlighted rows are the 303 days on GMT:

London to Singapore hour by hour

Each row is a full hour in London, from 6 AM to 11 PM, with the Singapore time 7 hours ahead or 8 hours ahead. Highlighted: the 1 hour when London and Singapore are both inside 9 AM to 5 PM, with a gap of 7 hours.

Office hours and the best time to meet

With a 9:00 AM to 5:00 PM workday on both sides, for each gap of the year:

• 7 hours apart (BST with SGT), 210 days of 2026: 1 hour of shared office time: 9:00 AM to 10:00 AM in London is 4:00 PM to 5:00 PM in Singapore. The latest start for a one-hour meeting is 9:00 AM in London, 4:00 PM in Singapore.
• 8 hours apart (GMT with SGT), 155 days of 2026: No hour of the London workday falls inside the Singapore workday. The smallest compromise is 8:30 AM in London, 4:30 PM in Singapore: an extra 30 minutes in each city. At the other end of the day, 2:30 AM in London is 10:30 AM in Singapore, which means 6 hours 30 minutes in London outside office hours.

The workweek in London and Singapore

For a Monday to Friday week with 9-to-5 office hours in both cities:

The first office hour of the week belongs to Singapore: Monday at 9:00 AM there is Monday at 2:00 AM in London. The last belongs to London, whose Friday 5:00 PM is Saturday 12:00 AM in Singapore. Over a Monday to Friday week, London and Singapore share 5 hours of office time with the usual gap of 7 hours.

From 5:00 PM until midnight in London, it is already the next day in Singapore. That is 7 hours out of every 24.

A rule of thumb: add 7 hours to go from London to Singapore, or 8 hours in the weeks with the other gap. 8:00 PM in London is 3:00 AM the next day in Singapore.

London and Singapore against UTC
