Timezone converter
PST to BST currently uses Pitcairn Time in America/Los_Angeles and Bangladesh Time in Asia/Dhaka as the live reference pair, with a +13h live gap. PST to BST matters whenever Los Angeles and Dhaka need to coordinate across a +13h gap. The PST side covers United States and Mexico, while BST covers Bangladesh and United Kingdom — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Last updated recently. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.
BST is ambiguous in this dataset, so the live converter uses Asia/Dhaka as the busiest reference zone while the city list below shows the wider label family.

Based on the busiest city and zone usage found in the current dataset.
PST (Los Angeles, -07:00) to BST (Dhaka, +06:00) is currently a +13h conversion. Live coverage on the PST side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the BST side draws from Dhaka, London, Abidjan, and Bamako.
PST to BST matters whenever Los Angeles and Dhaka need to coordinate across a +13h gap. The PST side covers United States and Mexico, while BST covers Bangladesh and United Kingdom — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
This pair is trans-Pacific, with one side in the Americas and the other in Asia or Oceania. The +13h gap is large enough that morning on one side reliably overlaps evening on the other, which is why this conversion mostly serves global supply chains, gaming launch schedules, and follow-the-sun engineering.
PST follows seasonal clock changes through America/Los_Angeles, while BST stays on a fixed offset year-round. That asymmetry is the real differentiator on this page: the gap widens or narrows by an hour twice a year, so calendar invites scheduled in one season often look wrong in the other.
PST and BST sit exactly 13h 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 BST is pinned to America/Los_Angeles -> Asia/Dhaka, with the shorthand labels shown as context. The city anchors are Los Angeles, Tijuana, San Diego, Mexicali on the PST side and Dhaka, London, Abidjan, Bamako on the BST side, with +13h between the live reference zones.
The 12 popular-hour answers include 3 same-day conversions, 9 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), GMT-7 (From side), MST (From side), YT (From side), BTT (To side), IOT (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/BST is a long-haul handoff gap: America/Los_Angeles currently reads -07:00, Asia/Dhaka reads +06:00, and the live delta is +13h. This class decides whether the page behaves like a same-day planner or a handoff planner.
America/Los_Angeles changes from -07:00 (PDT) to -08:00 (PST) on November 1, 2026 at about 1:00 AM.
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 3 same-day answers, 9 next-day answers, 0 previous-day answers. That mix is specific to the current America/Los_Angeles -> Asia/Dhaka 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 -> Asia/Dhaka, country anchors, city anchors, calendar notes, and day-shift examples.
PST and BST are not currently a same-offset pair; the live delta is +13h. Same-offset neighbors are still listed because users often confuse nearby abbreviations.
PDT (From side, -07:00), GMT-7 (From side, -07:00), MST (From side, -07:00), YT (From side, -07:00), BTT (To side, +06:00), IOT (To side, +06:00) The page keeps these labels visible so SGT/HKT/GST-style clusters do not blur into one generic offset page.
PST/BST uses 3 same-day answers, 9 next-day answers, 0 previous-day answers; 0h strict workday overlap; source zones America/Los_Angeles and Asia/Dhaka; country anchors United States, Mexico, and Canada -> Bangladesh, United Kingdom, and Ivory Coast.
Common places, calendars, markets, languages, and operating contexts behindPST and BST.
BST
BST is British Summer Time when used with Europe/London, not a generic abbreviation for every source that writes BST. It appears in UK summer schedules, London events, rail timetables, broadcasts, and company calendars while the UK is one hour ahead of GMT.
BST
A BST conversion should keep the date and Europe/London reference visible because the UK moves back to GMT in winter. A source that says BST outside the summer window may be using the label incorrectly or referring to a different abbreviation meaning.
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 and PDT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
PST and GMT-7 match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
PST and MST match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
PST and YT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
PST and AKDT are close enough to be confused in search, but they are not the same clock label and should be pinned to exact IANA zones.
PST and AKST are close enough to be confused in search, but they are not the same clock label and should be pinned to exact IANA zones.
BST and GMT are close enough to be confused in search, but they are not the same clock label and should be pinned to exact IANA zones.
BST and BTT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
BST and IOT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.

PST is a North or South American civil-time label, currently 7h behind UTC at -07:00. 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 -07:00 (PDT). Those cities are what give PST its actual feel rather than the abstract offset. PST currently shows -07:00, but America/Los_Angeles observes seasonal clock changes — the next transition is around November 1, 2026. 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 November 1, 2026. 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 -07:00, 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 (-07:00, Currently sits on the same UTC offset); GMT-7 (-07:00, Currently sits on the same UTC offset); MST (-07:00, Currently sits on the same UTC offset); YT (-07:00, Currently sits on the same UTC offset); AKDT (-08:00, Runs on a nearby UTC offset); AKST (-08:00, 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.
BST is reused across 3 different meanings in this dataset — Bangladesh Time, Greenwich Mean Time, and Bougainville Time — which is why the short code alone is not enough to identify a place. Each meaning maps to its own IANA zone family and its own DST behavior, and they happen to share the same letters by historical accident more than by design. The busiest cities using BST in the current catalog are Dhaka, London, Abidjan, Bamako, and Chattogram. The lead live reference on this page is Dhaka (Asia/Dhaka), currently at +06:00 (GMT+6). Those cities are what give BST its actual feel rather than the abstract offset. Because BST spans UTC+00:00 to UTC+11:00 across the active meanings, software, calendars, and contracts should always pin a specific IANA zone such as Asia/Dhaka or a literal UTC offset. The short label is fine for headlines and chat; it is the wrong primitive for storing or scheduling timestamps.
BST appears with 3 distinct meanings in current data, splitting across UTC+00:00 to UTC+11:00. The short label looks tidy in writing but quietly hides which place you mean — pick a city, a country, or an IANA zone before it matters. Asia/Dhaka does not show an offset change in the next year, which makes BST predictable for short-term scheduling. Predictable is not the same as permanent — civil-time rules still get changed by governments on relatively short notice. For precise work, the safest equivalent of BST is the exact IANA zone used by your city or system. Asia/Dhaka sits at +06:00, ahead of UTC, which means daily logs in this zone reach a new calendar date before UTC does — a small detail that breaks date-based reporting if missed.
BST should not be blindly swapped with nearby labels. Adjacent references in the catalog: GMT (+01:00, Shares the greenwich time family); BTT (+06:00, Currently sits on the same UTC offset); IOT (+06:00, Currently sits on the same UTC offset); KGT (+06:00, Currently sits on the same UTC offset); OMST (+06:00, Currently sits on the same UTC offset); CCT (+06:30, Runs on a nearby UTC offset).
BST has 3 meaning records, offset range UTC+00:00 to UTC+11:00, labels Bangladesh Time, Greenwich Mean Time, Bougainville Time, and 24 country footprints across 24 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.
BST country anchor Bangladesh: Bangladesh, officially the People's Republic of Bangladesh, is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of almost 176 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation's political, financial, and cultural centre, with its most affluent neighborhood Gulshan being among the most posh neighborhoods in South Asia. Chittagong is the second-largest city and the busiest port of the country. Source: Wikipedia.
BST is British Summer Time when used with Europe/London, not a generic abbreviation for every source that writes BST. It appears in UK summer schedules, London events, rail timetables, broadcasts, and company calendars while the UK is one hour ahead of GMT.
A BST conversion should keep the date and Europe/London reference visible because the UK moves back to GMT in winter. A source that says BST outside the summer window may be using the label incorrectly or referring to a different abbreviation meaning.
PST/BST uses America/Los_Angeles -> Asia/Dhaka, offset delta +13h, overlap 0h, route /convert/pst/bst/, and live abbreviation readings PDT/GMT+6.
Reference fields include this converter pair's abbreviation records, representative IANA zones, current offsets, city anchors, country profiles, overlap math, conversion examples, and dossier notes.
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.
BST coverage is led by Dhaka, Bangladesh, London, United Kingdom, Abidjan, Ivory Coast, and Bamako, Mali, with 2 more anchoring the wider label family. Combined with the PST side, this conversion ends up describing trans-Pacific outsourcing handoffs, gaming and entertainment release windows, and follow-the-sun engineering rotations.

PST to BST ranges from PST 9:00 AM (which lands at BST 10:00 PM) through PST 9:00 PM (BST 10:00 AM). Most of those slots fall on a different calendar day on the BST side, which is why this direction always needs explicit dates in invites and ticket comments — the time alone is not enough.
BST to PST ranges from BST 9:00 AM (which lands at PST 8:00 PM) through BST 9:00 PM (PST 8:00 AM). With no clean 9-to-5 overlap between BST and PST, both ends of this range push outside standard hours — useful for recorded standups and async work, awkward for live calls.
These direct answers are here for the exact-intent searches people actually use, like “10 AM PST to BST” or “4 PM PST in BST”.
8 AM PST = 9:00 PM BST (21:00). On today's live calendar that lands on Sun, May 24 in BST, which means the answer is a same day conversion rather than a static offset lookup.
9 AM PST = 10:00 PM BST (22:00). On today's live calendar that lands on Sun, May 24 in BST, which means the answer is a same day conversion rather than a static offset lookup.
10 AM PST = 11:00 PM BST (23:00). On today's live calendar that lands on Sun, May 24 in BST, which means the answer is a same day conversion rather than a static offset lookup.
11 AM PST = 12:00 AM BST (00:00). On today's live calendar that lands on Mon, May 25 in BST, which means the answer is a next day conversion rather than a static offset lookup.
12 PM PST = 1:00 AM BST (01:00). On today's live calendar that lands on Mon, May 25 in BST, which means the answer is a next day conversion rather than a static offset lookup.
1 PM PST = 2:00 AM BST (02:00). On today's live calendar that lands on Mon, May 25 in BST, which means the answer is a next day conversion rather than a static offset lookup.

The live gap is +13h right now, based on America/Los_Angeles at -07:00 and Asia/Dhaka at +06:00. America/Los_Angeles changes offset on November 1, 2026, so the gap moves to +14h after that transition.
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.
