The two zones in context

BST vs PST — cities and working rhythm

BST — British Summer Time
Primary cities: London, Dublin, Edinburgh (summer only)

UK / Ireland summer offset (last Sunday of March to last Sunday of October) — UTC+1, same as CET. During BST, London aligns with continental European working hours rather than the standard 1-hour gap. Winter reverts to GMT (UTC+0).

PST — Pacific Standard Time
Primary cities: Los Angeles, San Francisco, Seattle, Vancouver, San Diego

US West Coast — home of Silicon Valley, LA entertainment, and the SaaS / VC ecosystem. Business hours 9 AM – 6 PM PT. Startup / tech culture stretches later than East Coast: it's common for calendar invites from West Coast product teams to run through 8 PM PT.

Time gap: PST is 9.0 hours behind BST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
