Planning a call between Singapore and London
Best window: 4 pm to 5 pm in Singapore (9:00 AM to 10:00 AM in London). In that stretch both cities sit inside core 9-to-5 hours, so neither side takes the call early or late.
Daylight saving
Singapore does not change its clocks. It stays on UTC+8 (SGT) all year, so the gap to the other city only moves when the other city shifts.
London is on UTC+1 (BST). Clocks go back one hour on Sunday, October 25, 2026, moving it to UTC+0. Between that date and the other city’s own change, the gap between them is an hour different from usual.
