Scheduling guide

San Francisco and London are 8 hours apart year-round: both observe daylight saving and switch within weeks of each other, so the gap stays constant. The workday overlap is thin: 9:00 to 10:00 AM Pacific is 5:00 to 6:00 PM London, just one hour.

That narrow window shapes everything. The best slot is 9:00 AM San Francisco / 5:00 PM London: SF is fresh, London is wrapping up but still at the desk. Anything later in San Francisco pushes London into the evening, which works occasionally but burns goodwill fast.

Practical playbook: keep the daily standup inside the window and move everything else async. If you need a longer workshop, split it across two days rather than dragging London past 7:00 PM. And protect the window fiercely: a 9:30 AM Pacific meeting that runs long is a 6:30 PM London finish. Start on time, end early, and publish notes so nobody needs a second call.
