Best Time to Call London from Singapore
🕐 Live Timezone Overlap: London & Singapore
London and Singapore sit 7 hours apart, with Singapore ahead. That gap is wide enough to make spontaneous calls difficult, but tight enough that a structured slot does exist. The 2-hour window where both cities are inside a standard 9am to 6pm working day is narrow, so planning ahead matters. Singapore hosts many multinational APAC headquarters, meaning the Singapore side of a call is often high-stakes and diary-heavy. Getting the time right is not a courtesy, it is a practical necessity.
Time Difference: London and Singapore
Singapore is currently 7 hours ahead of London. The live offsets are London UTC+1 and Singapore UTC+8. London observes daylight saving and Singapore does not, so the offset shifts twice a year if both sides aren't already aligned.
Singapore runs UTC+8 year-round and does not observe daylight saving time. London does. In winter, London sits at UTC+0, making the gap exactly 8 hours. In summer, London moves to UTC+1, which closes that gap to 7 hours. The difference therefore shifts twice a year: when British Summer Time begins in spring, the offset narrows from 8 to 7 hours, and it widens back to 8 hours each autumn when clocks return to GMT. Singapore's side of the clock never changes.
Best Times to Meet
The overlap is 2 hours: 9am to 11am in London, which is 4pm to 6pm in Singapore. Inside that 2-hour window, 9am to 10am London time is generally the cleaner slot. London offices tend to be settled by 9am, and the Singapore team is approaching end of day rather than already in wind-down. Avoid 10:30am onwards in London if the Singapore team keeps a firm 6pm close. On Fridays, note that London offices often wind down earlier than usual, so morning slots are especially preferable.

Tips for Scheduling Across London and Singapore
- Book London-Singapore calls between 9am and 10am London time to catch Singapore before 6pm closes.
- When British Summer Time starts each spring, your Singapore overlap shifts: recheck standing meeting invites immediately.
- Singapore observed no DST changes in 2024 or any recent year; the burden of adjustment always falls on the London side.
- Chinese New Year can reduce Singapore availability for several days beyond the two public holidays; plan project deadlines accordingly.
- London Fridays tend to wind down by 4pm; avoid scheduling Singapore calls late on a Friday London morning.
Public Holidays and Working Weeks
Both cities follow a Monday to Friday working week with 9am to 6pm as the standard window. In London, watch for the May Bank Holiday on the first Monday in May and Christmas Day on 25 December. In Singapore, Chinese New Year falls in January or February and carries two public holidays plus possible extended absences. National Day on 9 August is another Singapore date to check. Cross-city meetings should be confirmed against both calendars well in advance.
