How many hours apart are Sydney and San Francisco?

The gap varies between 17 and 21 hours depending on the season and which side is observing daylight saving time. Sydney is ahead of San Francisco, so when it is Monday morning in Sydney it is often still Sunday in San Francisco. The closest the two clocks ever get is during the brief window when both cities are on standard time.

What is the best meeting time for Sydney and San Francisco?

The only workable overlap is early morning in San Francisco paired with late afternoon or early evening in Sydney. A meeting at 8–9 AM PT lands at 3–4 AM AEDT in summer, which is too early. In the shoulder season the gap narrows to 17 hours, making 7 AM PT correspond to around midnight in Sydney—still not ideal, but the best available window.

Should Sydney or San Francisco sacrifice more for meetings?

Because San Francisco is the smaller timezone cluster in this pairing, rotating the burden is the fairest approach. Some meetings can start at 7–8 AM PT while others ask Sydney to join at 6–7 PM AEDT. Recording every meeting and writing detailed async summaries reduces how often either side must attend at an inconvenient hour.
