Why Choose Our PST to GMT Converter

Align PST–GMT Meetings Instantly

When someone in United States suggests 9:00 AM PST, that's 5:00 PM GMT. This converter shows the overlap so both sides agree on one slot — no back-and-forth.

Spot Date-Line Shifts at a Glance

Late-night PST times can land on a different date in GMT because of the 8 hours offset. The converter labels "next day" or "previous day" next to the result so you never send a message a day early or miss a deadline.

Business-hours overlap

US West Coast to UK — SaaS Europe launches, VC crossovers

PST is 8 h behind GMT (7 h during PDT/BST). Practical overlap: 9-10 AM PT = 5-6 PM GMT (end of UK working day catches start of US West one). This is the meeting slot for SF-based SaaS companies launching in Europe and for US venture funds with London LPs. Note: BST/GMT and PDT/PST DST cutovers are 2 weeks apart in spring (March), so mid-March the actual gap wobbles between 7 and 8 h for a fortnight.

The two zones in context

PST vs GMT — cities and working rhythm

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.

GMT — Greenwich Mean Time
Primary cities: London, Dublin, Lisbon, Accra, Reykjavík

UK / Ireland / Iceland / Portugal / West Africa. Business hours 9 AM – 5:30 PM GMT typically. Note: London is on GMT in winter, BST (GMT+1) in summer — but "GMT" gets used loosely all year in scheduling contexts. Financial-services London anchors the European trading day.

Time gap: GMT is 8.0 hours ahead of PST (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
