Best Meeting Time: San Francisco to Singapore
🕐 Live Timezone Overlap: San Francisco & Singapore
San Francisco and Singapore sit 15 hours apart, with Singapore ahead. That gap is large enough to make any synchronous meeting a stretch for at least one party. Working hours in the two cities do not overlap at all on a standard 9am to 6pm basis. Any call requires someone to start very early or finish very late. Teams scheduling across this corridor regularly face that trade-off, and knowing the numbers in advance makes planning considerably less painful.
Time Difference: San Francisco and Singapore
Singapore is currently 15 hours ahead of San Francisco. The live offsets are San Francisco UTC-7 and Singapore UTC+8. San Francisco 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 observes no daylight saving time. San Francisco uses Pacific Time, currently UTC-7 during daylight saving and UTC-8 in standard time. That means the gap between San Francisco and Singapore is 15 hours when the US is on summer time, and widens to 16 hours when San Francisco returns to standard time each November. The switch happens on the first Sunday in November and reverses on the second Sunday in March.
Best Times to Meet
There is no overlap between San Francisco and Singapore working hours. Zero hours of shared 9am to 6pm time exist between the two cities. In practice, the least painful arrangement is an early morning call in Singapore, say 8am to 9am SGT, which lands at 5pm to 6pm the previous calendar day in San Francisco during US summer time. San Francisco tech teams sometimes run schedules to 7pm Pacific, which can help. Singapore multinational offices treat 9am to 6pm as a firm norm, so slots before 9am SGT require explicit agreement.

Tips for Scheduling Across San Francisco and Singapore
- When San Francisco is on standard time, the gap widens to 16 hours: recalculate recurring invites each November and March.
- Singapore's Chinese New Year period brings extended absences beyond the two public holidays; confirm availability before scheduling.
- An 8am Singapore slot lands at 5pm the prior day in San Francisco during US summer time, the most workable pairing available.
- Mid-July through Labour Day sees high vacation density across SF Bay Area tech; Singapore availability does not dip the same way.
- San Francisco teams sometimes run to 7pm Pacific; confirm your counterpart's actual end time before booking a late-day call.
Public Holidays and Working Weeks
Both cities follow a standard Monday to Friday working week. Key holidays to watch include Independence Day on 4 July and Thanksgiving on the fourth Thursday in November for San Francisco, and Chinese New Year in January or February for Singapore, which brings two public holidays plus extended absences. National Day on 9 August is another Singapore date to note. Any meeting series spanning this corridor should be checked against both calendars before invites go out.
