How to Convert GMT to PST
Open the GMT to PST converter: Go to https://www.xconvert.com/time-converter/gmt-to-pst-converter to load a visual comparison grid with GMT and PST ready for side-by-side viewing. This page is useful when you need to schedule a call between a London-based team working on GMT and colleagues on the US or Canadian West Coast using PST, especially for support, media, software, and cross-border operations.
Add comparison cities if your schedule involves more than two regions: Click + Add City and search for cities that commonly sit alongside GMT and PST workflows, such as London for UK business hours, Los Angeles for US West Coast meetings, or Vancouver for Canadian operations. This is especially practical for remote teams handling product launches, customer support coverage, or agency work spanning the United Kingdom, the United States, and Canada.
Select the meeting window on the grid: Click Select, then drag across the colored timeline on the GMT row to highlight a time range in purple; you can adjust the left and right handles or drag the center to move the whole block. For example, dragging a slot around 9:00 GMT shows 1:00 PST, while 12:00 GMT aligns with 4:00 PST and 15:00 GMT aligns with 7:00 PST, helping you quickly see whether a planned handoff or call lands inside normal work hours or very early in the PST day.
Export and share the selected time: Once a range is highlighted, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is helpful when a UK operations manager needs to send a confirmed meeting time to a California client or a distributed team so everyone receives the event in their own local calendar without manually converting GMT to PST.
Understanding the GMT to PST Time Difference
GMT is UTC+0 and PST is UTC-8, so PST is 8 hours behind GMT. In practical terms, when the workday starts in a GMT location such as the United Kingdom, the PST region is still much earlier in the day, which is why morning meetings in GMT often appear before standard office hours on the US and Canadian Pacific coast.
The clearest way to understand the gap is through direct examples: 9:00 GMT = 1:00 PST, 12:00 GMT = 4:00 PST, 15:00 GMT = 7:00 PST, and 18:00 GMT = 10:00 PST. These examples show that a late-morning or early-afternoon GMT schedule often maps to very early morning in PST, while an early evening GMT meeting can still fall within the morning on the Pacific side.
Daylight saving time can change the relationship because GMT is a standard-time abbreviation and its daylight counterpart is IST, while PST is a standard-time abbreviation and its daylight counterpart is PDT. During months when one or both regions move off standard time, the difference may no longer match the standard 8-hour gap, so the exact seasonal alignment depends on whether the locations are observing their daylight variant rather than GMT or PST.
GMT is used across countries including Burkina Faso, Gambia, Ghana, Guernsey, Guinea, Guinea-Bissau, Iceland, Ireland, Isle of Man, Ivory Coast, Jersey, Liberia, Mali, Mauritania, Saint Helena, Sao Tome and Principe, Senegal, Sierra Leone, Togo, and the United Kingdom. PST is used in parts of Canada, Mexico, the Philippines, and the United States, which makes this conversion especially relevant for international customer support, logistics coordination, travel planning, and media distribution across Atlantic and Pacific markets.
Best Times for Calls and Meetings Between GMT and PST
Because PST is 8 hours behind GMT, the most practical overlap usually appears when the GMT side schedules later in its workday and the PST side joins early in its morning. The examples make this clear: 15:00 GMT = 7:00 PST and 18:00 GMT = 10:00 PST, so the GMT afternoon corresponds to a morning window in PST that is more realistic for live meetings, sales calls, and engineering syncs.
A 12:00 GMT = 4:00 PST conversion can work for teams that start early on the Pacific coast, but it is often too early for standard office scheduling unless the meeting is high priority or the PST team works flexible hours. By contrast, 9:00 GMT = 1:00 PST is usually impractical for most business calls because it falls deep in the night for the Pacific side.
For recurring meetings between UK-based staff and West Coast teams in the United States or Canada, a GMT afternoon slot is usually easier to maintain than a GMT morning slot. This is particularly common in software development, digital marketing, film and streaming operations, and customer success teams that need at least a small overlap between European office hours and Pacific business hours.
If you are arranging interviews, vendor calls, or handoffs, use the grid to compare a narrow block rather than a single hour. Highlighting a two-hour range lets you see whether a GMT-side late afternoon still gives the PST side enough morning availability for preparation, discussion, and follow-up before the rest of their workday fills up.
Frequently Asked Questions
What is the time difference between GMT and PST?
GMT is UTC+0 and PST is UTC-8, so PST is 8 hours behind GMT. That means when the clock moves forward through the day in GMT, the Pacific Standard Time zone is still eight hours earlier, which has a major effect on scheduling across Europe and the West Coast of North America.
When is 9 AM GMT in PST?
9:00 GMT = 1:00 PST. This is an important conversion for anyone trying to schedule a morning UK meeting with a California, Vancouver, or other Pacific-based participant, because it lands in the middle of the night on the PST side and is usually not suitable for normal business hours.
When is 12 PM GMT in PST?
12:00 GMT = 4:00 PST. For business use, this means a noon meeting in a GMT-based office reaches Pacific participants very early in the morning, which may work for shift-based teams, operations staff, or executives who start early, but is not ideal for most standard office calendars.
When is 3 PM GMT in PST?
15:00 GMT = 7:00 PST. This is one of the more workable examples for cross-time-zone coordination because it places the GMT team in mid-afternoon and the PST team at the beginning of the business day, making it a common choice for project updates and client check-ins.
When is 6 PM GMT in PST?
18:00 GMT = 10:00 PST. This timing is often more comfortable for the Pacific side because it falls in the morning, though it pushes the GMT side toward the end of the business day and may be less convenient for teams that avoid late meetings.
Does the difference between GMT and PST change during DST?
Yes, the difference can change during daylight saving periods because GMT is the standard-time abbreviation and its daylight counterpart is IST, while PST is the standard-time abbreviation and its daylight counterpart is PDT. If one or both locations are observing daylight time instead of their standard abbreviation, the seasonal gap may differ from the standard 8-hour GMT-to-PST relationship.
What is the best meeting time between GMT and PST?
The best meeting window is usually when the GMT side meets in the afternoon and the PST side joins in the morning. Based on the examples, 15:00 GMT = 7:00 PST and 18:00 GMT = 10:00 PST, so later GMT slots generally create the most realistic overlap for live collaboration.
Which countries commonly use GMT and PST?
GMT is used in countries and territories including the United Kingdom, Ireland, Iceland, Ghana, Senegal, Sierra Leone, Togo, Liberia, Mali, Mauritania, Guinea, Guinea-Bissau, Gambia, Burkina Faso, Ivory Coast, Sao Tome and Principe, Saint Helena, Guernsey, Jersey, and the Isle of Man. PST is used in parts of Canada, Mexico, the Philippines, and the United States, making GMT-to-PST conversion relevant for international trade, outsourcing, media scheduling, and remote team coordination.
