Timezone converter
PST to GMT currently uses Pitcairn Time in America/Los_Angeles and Greenwich Mean Time in Europe/London as the live reference pair, with a +8h live gap. PST to GMT matters whenever Los Angeles and London need to coordinate across a +8h gap. The PST side covers United States and Mexico, while GMT covers United Kingdom and Ivory Coast — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

Based on the busiest city and zone usage found in the current dataset.
PST (Los Angeles, -08:00) to GMT (London, +00:00) is currently a +8h conversion. Live coverage on the PST side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the GMT side draws from London, Abidjan, Bamako, and Dakar.
PST to GMT matters whenever Los Angeles and London need to coordinate across a +8h gap. The PST side covers United States and Mexico, while GMT covers United Kingdom and Ivory Coast — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
PST is grounded here by United States, Mexico, and Canada. GMT means Greenwich, UK winter civil time, Iceland, Atlantic islands, and West African zero-offset countries; watch UK bank holidays, Irish public holidays, and West African national calendars. The curated side is where most same-offset duplication risk is removed, because it names the civil calendar and operating context users actually mean.
This pair crosses the Atlantic, with one side in the Americas and the other in Europe or Africa. The +8h gap is small enough that there is still a real shared midday window, which is why transatlantic finance, broadcasting, and conference scheduling lean on this conversion.
Both PST (America/Los_Angeles) and GMT (Europe/London) observe daylight saving, but the shift dates do not always align. Expect short mismatch windows in spring and autumn when one side has changed and the other has not, which moves the live gap by an hour for several weeks at a time.
PST and GMT sit exactly 8h apart, which leaves no shared 9-to-5 block. Live meetings have to bend one side's day, so most teams settle for one of two narrow windows: very early on the late side, or very late on the early side. That makes async messages, recorded standups, and clear handoff notes more valuable than calendar invites.

Same-offset labels can share the same hour while still landing in different countries, calendars, cities, and workday windows. These notes show the practical context behind this conversion.
PST to GMT is pinned to America/Los_Angeles -> Europe/London, with the shorthand labels shown as context. The city anchors are Los Angeles, Tijuana, San Diego, Mexicali on the PST side and London, Abidjan, Bamako, Dakar on the GMT side, with +8h between the live reference zones.
The 12 popular-hour answers include 8 same-day conversions, 4 next-day conversions, and 0 previous-day conversions. That distribution is what separates this page from a static offset chart.
Nearby labels sharing a current offset include PDT (From side), UTC (To side), WEST (To side), WET (To side). They may match mathematically, but their country calendars, city anchors, and common search intent differ from this exact pair.

Offset behavior, DST gap changes, local calendar evidence, and the day-shift pattern across the most common conversion hours.
PST/GMT is a long-haul handoff gap: America/Los_Angeles currently reads -08:00, Europe/London reads +00:00, and the live delta is +8h. This class decides whether the page behaves like a same-day planner or a handoff planner.
America/Los_Angeles changes on March 14, 2027 at about 3:00 AM, moving from -08:00 to -07:00. Europe/London changes on March 28, 2027 at about 2:00 AM, moving from +00:00 to +01:00.
No country holiday snapshot is attached to this exact pair yet, so the page leans on city anchors, IANA zones, offsets, and the live conversion table instead of pretending a local calendar exists.
Across the 12 popular-hour answers, this pair has 8 same-day answers, 4 next-day answers, 0 previous-day answers. That mix is specific to the current America/Los_Angeles -> Europe/London relationship and helps users see whether dates must be written explicitly in invites, travel plans, and release schedules.
Same-offset converter clusters can look identical if the page only shows a numeric offset. This audit states whether the route should be indexed, which canonical peer it follows when consolidated, and what pair-specific evidence keeps the page useful.
This pair remains indexable because the route has enough pair-specific context: America/Los_Angeles -> Europe/London, country anchors, city anchors, calendar notes, and day-shift examples.
PST and GMT are not currently a same-offset pair; the live delta is +8h. Same-offset neighbors are still listed because users often confuse nearby abbreviations.
PDT (From side, -08:00), UTC (To side, +00:00), WEST (To side, +00:00), WET (To side, +00:00) The page keeps these labels visible so SGT/HKT/GST-style clusters do not blur into one generic offset page.
PST/GMT uses 8 same-day answers, 4 next-day answers, 0 previous-day answers; 0h strict workday overlap; source zones America/Los_Angeles and Europe/London; country anchors United States, Mexico, and Canada -> United Kingdom, Ivory Coast, and Mali.
Common places, calendars, markets, languages, and operating contexts behindPST and GMT.
GMT
GMT is not just a country clock. In this dataset it spans London, Dublin, Reykjavik, West Africa, Atlantic islands, and reference-style public schedules. It is commonly used as a source label in broadcasts, aviation-adjacent notices, release notes, and public event listings, but software and contracts often prefer UTC or a precise IANA zone.
GMT
For UK-facing planning, GMT needs a seasonal caveat: Europe/London can display British Summer Time while a sender still casually writes GMT. That is why converter pages using GMT should keep the exact reference zone visible instead of pretending the three-letter label is always enough.
Same-offset conversions can still land in different public-holiday, language, currency, and city-anchor contexts. These rows use the country profile and holiday snapshots behind each side of the pair.

These are the labels most likely to be confused with either side of this conversion. A matching UTC offset does not mean the same country, calendar, market, source convention, or user intent.

PST is a North or South American civil-time label, currently 8h behind UTC at -08:00. The label covers 4 IANA zones across 4 countries, with Los Angeles as the busiest live reference. The busiest cities using PST in the current catalog are Los Angeles, Tijuana, San Diego, Mexicali, and San Jose. The lead live reference on this page is Los Angeles (America/Los_Angeles), currently at -08:00 (PST). Those cities are what give PST its actual feel rather than the abstract offset. PST currently shows -08:00, but America/Los_Angeles observes seasonal clock changes — the next transition is around March 14, 2027. That means the offset on this page is a snapshot, not a permanent fact, so long-range scheduling should pin the underlying IANA zone instead of the abbreviation.
PST reads cleanly across the Americas in this dataset, but the same letters can mean different things elsewhere (notably CST, EST, and IST overlap with non-American labels). Pin the IANA zone when the audience is international. America/Los_Angeles has an upcoming offset change on March 14, 2027. After that point, PST on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation. For precise work, the safest equivalent of PST is the exact IANA zone used by your city or system. America/Los_Angeles sits at -08:00, behind UTC, which means daily logs in this zone reach a new calendar date after UTC does — relevant for date-aligned reports and billing cutoffs.
PST should not be blindly swapped with nearby labels. Adjacent references in the catalog: PDT (-08:00, Currently sits on the same UTC offset); AKDT (-09:00, Runs on a nearby UTC offset); AKST (-09:00, Runs on a nearby UTC offset); GAMT (-09:00, Runs on a nearby UTC offset); GMT-7 (-07:00, Runs on a nearby UTC offset); MDT (-07:00, Runs on a nearby UTC offset).
PST has 1 meaning record, offset range UTC-08:00 to UTC-07:00, labels Pitcairn Time, and 4 country footprints across 4 IANA zones.
GMT started as Greenwich Mean Time and now lives a double life: a civil-time label still used by the UK and parts of West Africa in winter, and a casual synonym for UTC in broadcasting and public schedules. The two roles overlap most of the time, but precise work treats them as distinct. The busiest cities using GMT in the current catalog are London, Abidjan, Bamako, Dakar, and Kumasi. The lead live reference on this page is London (Europe/London), currently at +00:00 (GMT+0). Those cities are what give GMT its actual feel rather than the abstract offset. GMT has a local identity beyond its offset: Greenwich, UK winter civil time, Iceland, Atlantic islands, and West African zero-offset countries. Calendar signals such as UK bank holidays, Irish public holidays, West African national calendars, and Icelandic no-DST scheduling and operational signals such as broadcast timestamps, public event listings, shipping and aviation-adjacent notices, and release notes written for a general audience are why this abbreviation should not be flattened into a same-offset neighbor. GMT currently shows +00:00, but Europe/London observes seasonal clock changes — the next transition is around March 28, 2027. That means the offset on this page is a snapshot, not a permanent fact, so long-range scheduling should pin the underlying IANA zone instead of the abbreviation.
GMT is not heavily split in the current catalog, but the short label still hides the underlying IANA zone and any future policy change. The safe pattern is to write the abbreviation for humans and the zone for machines. GMT behaves as a civil label in several places and as a public shorthand for UTC elsewhere; systems should store UTC or an IANA zone when the distinction matters. Not the same as GST, HKT, or SGT: GMT is a zero-offset reference family, not a Gulf, Hong Kong, or Singapore civil calendar. Europe/London has an upcoming offset change on March 28, 2027. After that point, GMT on this page will read a different UTC offset until the next transition, so any saved timestamp should anchor to the IANA zone rather than the abbreviation. GMT remains common in public schedules and broadcasting, while software teams almost always prefer UTC or an explicit IANA zone. The two are not technically identical (GMT is a civil-time label observed in winter; UTC is a continuously-corrected atomic standard), but they are close enough that mixing them rarely breaks anything in practice.
GMT should not be blindly swapped with nearby labels. Adjacent references in the catalog: UTC (+00:00, Often compared as a zero-offset reference); BST (+06:00, Shares the greenwich time family); WEST (+00:00, Currently sits on the same UTC offset); WET (+00:00, Currently sits on the same UTC offset); AZOST (-01:00, Runs on a nearby UTC offset); AZOT (-01:00, Runs on a nearby UTC offset).
GMT has 1 meaning record, offset range UTC+00:00 to UTC+02:00, labels Greenwich Mean Time, and 22 country footprints across 22 IANA zones.
PST country anchor United States: The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic consisting of 50 states and a federal capital district, Washington, D.C. The 48 contiguous states border Canada to the north and Mexico to the south, with the semi-exclave of Alaska in the northwest and the archipelago of Hawaii in the Pacific Ocean. The United States also asserts sovereignty over five major island territories and various uninhabited islands in Oceania and the Caribbean. It is a megadiverse country, with the world's third-largest land area and third-largest population, exceeding 341 million. Source: Wikipedia.

It is commonly used as a source label in broadcasts, aviation-adjacent notices, release notes, and public event listings, but software and contracts often prefer UTC or a precise IANA zone.
For UK-facing planning, GMT needs a seasonal caveat: Europe/London can display British Summer Time while a sender still casually writes GMT. That is why converter pages using GMT should keep the exact reference zone visible instead of pretending the three-letter label is always enough.
PST/GMT uses America/Los_Angeles -> Europe/London, offset delta +8h, overlap 0h, route /convert/pst/gmt/, and live abbreviation readings PST/GMT+0.
PST coverage on this page is led by Los Angeles, United States, Tijuana, Mexico, San Diego, United States, and Mexicali, Mexico, with 2 more in the live dataset. That mix is what makes PST feel anchored to West Coast and Pacific-edge American activity in practice rather than just an abbreviation on a chart.
GMT coverage is led by London, United Kingdom, Abidjan, Ivory Coast, Bamako, Mali, and Dakar, Senegal, with 2 more anchoring the wider label family. Combined with the PST side, this conversion ends up describing transatlantic finance, broadcast scheduling, and same-day cross-border product launches. Local signals include broadcast timestamps, public event listings, and shipping and aviation-adjacent notices.

PST to GMT ranges from PST 9:00 AM (which lands at GMT 5:00 PM) through PST 9:00 PM (GMT 5:00 AM). With no clean 9-to-5 overlap between PST and GMT, both ends of this range push outside standard hours — useful for recorded standups and async work, awkward for live calls.

The live gap is +8h right now, based on America/Los_Angeles at -08:00 and Europe/London at +00:00. The zones change on different dates, so there is a DST mismatch window between March 14, 2027 and March 28, 2027. During that stretch the gap shifts to +7h before settling at +8h.
There is no strict 9 AM to 5 PM overlap right now, so this pair is better for handoffs, travel planning, or async coordination than for midday meetings.
