Best time to meet

There is no overlap between a normal 09:00–18:00 working day in Singapore and one in San Francisco. Any live meeting will ask one side to take the call outside working hours. For a recurring slot, use an async written update or rotate a recording instead of rotating the inconvenience.

Frequently asked questions

What is the time difference between Singapore and San Francisco?

Singapore is 15 hours ahead of San Francisco: UTC+8 versus UTC-7. Both figures include any daylight saving currently in force.

What is the best time to call from Singapore to San Francisco?

There is no hour that is comfortable for both. If the meeting is unavoidable, the least-bad options are the edges of each side's day — late morning in Singapore or early morning in San Francisco — and the burden should be explicit rather than assumed.

Is there any way to make Singapore–San Francisco meetings work?

Not through scheduling. With no overlap, the workable options are async written handoffs, recorded updates, or splitting coverage into two regional pods so that each pod works its own daylight hours.
