Planning a call between Seattle and Singapore
Best window: 5 pm to 6 pm in Seattle (8:00 AM to 9:00 AM in Singapore). There is no overlap inside a strict 9-to-5, but these hours fall within a normal 8-to-6 working day at both ends — one side takes it near the start of the day, the other near the end.
Daylight saving
Seattle is on UTC−7 (PDT). Clocks go back one hour on Sunday, November 1, 2026, moving it to UTC−8. Between that date and the other city’s own change, the gap between them is an hour different from usual.
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.
