Best time for work calls
If you are scheduling a call between London and San Francisco, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Best time for family calls
London and San Francisco have a comfortable window for a family call — no awkward alarms required. London is 8 hours ahead of San Francisco, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in London — that lands at 10 am to 2 pm in San Francisco, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
