This is a geography page, not a schedule. This site holds no flight schedules, fares or availability, and nothing here says any airline flies this pair or when. The distance is computed from the two airports' coordinates; the flying time is an estimate from that distance. Check the airline for what actually operates.

Distances are geodesic — the shortest path over the WGS-84 ellipsoid, the same basis published figures use. Real aircraft fly further, following airways and routing around weather and restricted airspace. The time estimate ignores wind, so the same route is genuinely quicker eastbound than westbound.

Singapore is currently 15 hours ahead of San Francisco. Both times on an airline itinerary are local to their own airport, so you cannot subtract them to get a duration. Offsets change with daylight saving, and the two ends do not always switch on the same date — the time zone planner resolves them for your actual travel date.
This route crosses the International Date Line. The calendar date changes by a full day on top of any time-zone shift, so the arrival date will not be the departure date plus the obvious amount. Book hotels and onward travel against the arrival date your itinerary actually shows. Why the date line does this →
