Best Time for a Call

There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 7:00 AM to 12:00 PM in PST, which is 4:00 PM to 9:00 PM in BST. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.

Comparing more than two places? The Overlap Zones tool shows working hours for several cities on one grid.
