Quick answer
1 PM PST is 9 PM GMT in London (winter) or 9 PM BST (summer). The 8-hour gap between Pacific Standard Time and UK time means early afternoon on the West Coast is already late evening in London.
How to use this time conversion
1 PM Pacific time reaches London at 9 PM 鈥?the UK evening. This is outside standard business hours for most London-based teams. For US West Coast teams working on Pacific time, the cut-off for reaching London during business hours is approximately 9 AM PST (5 PM London). For afternoon Pacific calls involving UK participants, asynchronous updates 鈥?a Slack message, a shared doc, or a recorded walkthrough 鈥?are the practical alternative.
For one-time calls, confirm the exact date before sending the invite. For recurring calls, use the Meeting Time Finder to verify the overlap stays inside working hours after every daylight saving change.
