Timezone converter
PST to JST currently uses Pitcairn Time in America/Los_Angeles and Japan Time in Asia/Tokyo as the live reference pair, with a +17h live gap. PST to JST matters whenever Los Angeles and Tokyo need to coordinate across a +17h gap. The PST side covers United States and Mexico, while JST covers Japan — 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 JST (Tokyo, +09:00) is currently a +17h conversion. Live coverage on the PST side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the JST side draws from Tokyo, Yokohama, Osaka, and Nagoya.
PST to JST matters whenever Los Angeles and Tokyo need to coordinate across a +17h gap. The PST side covers United States and Mexico, while JST covers Japan — 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 +17h 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 JST 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 JST sit exactly 17h apart, leaving roughly 1h of usable 9-to-5 overlap. That window is tight enough that recurring meetings tend to pile onto the same hour, which is why teams with this pair often consolidate cross-region work into a single anchor meeting per day.

Offset behavior, DST gap changes, local calendar evidence, and the day-shift pattern across the most common conversion hours.
PST/JST is a long-haul handoff gap: America/Los_Angeles currently reads -08:00, Asia/Tokyo reads +09:00, and the live delta is +17h. This class decides whether the page behaves like a same-day planner or a handoff planner.
America/Los_Angeles changes from -08:00 (PST) to -07:00 (PDT) on March 14, 2027 at about 3:00 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 0 same-day answers, 12 next-day answers, 0 previous-day answers. That mix is specific to the current America/Los_Angeles -> Asia/Tokyo 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/Tokyo, country anchors, city anchors, calendar notes, and day-shift examples.
PST and JST are not currently a same-offset pair; the live delta is +17h. Same-offset neighbors are still listed because users often confuse nearby abbreviations.

Common places, calendars, markets, languages, and operating contexts behindPST and JST.
JST
JST is Japan civil time, centered on Tokyo, Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, and the rest of the Japanese domestic timetable. The useful context is Japan's no-DST posture, yen-denominated business cycles, Tokyo Stock Exchange timing, rail and aviation punctuality, anime/game/media release schedules, and holiday clusters such as Golden Week and year-end closures.
JST
A JST conversion is often searched by teams coordinating with Japan specifically, not merely UTC+9. Product launches, live streams, travel arrivals, and support handoffs should account for Japanese business etiquette, local public holidays, and the difference between Japan's stable clock and regions where daylight saving changes the counterpart offset.
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.

Pair-specific dossier
PST to JST is one of the most common gaming, hardware, anime, and trans-Pacific travel conversions. Los Angeles, San Francisco, Seattle, and Vancouver source times frequently need to land in Tokyo, Osaka, Nagoya, or Fukuoka with the correct local date.
The intuitive trap is the date line. A Pacific evening announcement often lands in Japan the next day, while a Japan morning launch can appear on the previous afternoon or evening in California. During Pacific daylight time the gap changes by one hour.
This page should keep entertainment, product-launch, aviation, and engineering handoff contexts visible while reminding users that Japan's calendar does not follow US West Coast holidays.
Most often used for West Coast tech/media teams and fans converting Japan release times, livestreams, flight timings, or support windows into Pacific local time.
A 18:00 PST announcement is 11:00 JST the next day; a Tokyo 09:00 release is 16:00 PST on the previous day. Pacific daylight time compresses the gap by one hour, so recurring launches need date-aware conversion.
US Thanksgiving, Presidents' Day, Memorial Day, and Independence Day do not align with Japanese holidays such as Golden Week, Obon, Culture Day, and Labor Thanksgiving Day. Travel users should also check Japan rail/airport peak periods.
Not the same as PST/KST despite the same UTC+9 target offset. Japan and Korea have separate public holidays, markets, languages, and entertainment-release conventions.
Three-letter abbreviations are ambiguous. The IANA zone identifier above is the canonical reference; software, contracts, and calendar storage should use it instead of the abbreviation.
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 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.
PST and GAMT 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 MDT are close enough to be confused in search, but they are not the same clock label and should be pinned to exact IANA zones.
JST and GMT+9 match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
JST and KST match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
JST and PWT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
JST and WIT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
JST and YAKT match on offset right now, but the page should not collapse them: they carry different city anchors, country calendars, currencies, holidays, and user intent.
JST and ACWST 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 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.
JST is an Asian civil-time label, currently 9h ahead of UTC at +09:00. The lead reference is Tokyo, and the wider grouping reaches 1 country through 1 IANA zone. The busiest cities using JST in the current catalog are Tokyo, Yokohama, Osaka, Nagoya, and Sapporo. The lead live reference on this page is Tokyo (Asia/Tokyo), currently at +09:00 (GMT+9). Those cities are what give JST its actual feel rather than the abstract offset. JST is stable on Asia/Tokyo year-round, with no seasonal clock changes in the next year. That makes it a low-friction choice for recurring meetings and broadcast schedules — but software still prefers the IANA zone because governments can change civil-time rules independently of the short code.
JST resolves cleanly here, but Asian labels often share letters with American or European ones — IST is shared between India and Israel, for instance. Pinning Asia/Tokyo avoids that whole class of confusion. Asia/Tokyo does not show an offset change in the next year, which makes JST 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 JST is the exact IANA zone used by your city or system. Asia/Tokyo sits at +09:00, 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.
JST should not be blindly swapped with nearby labels. Adjacent references in the catalog: GMT+9 (+09:00, Currently sits on the same UTC offset); KST (+09:00, Currently sits on the same UTC offset); PWT (+09:00, Currently sits on the same UTC offset); WIT (+09:00, Currently sits on the same UTC offset); YAKT (+09:00, Currently sits on the same UTC offset); ACWST (+08:45, Runs on a nearby UTC offset).
JST has 1 meaning record, offset range UTC+09:00, labels Japan Time, and 1 country footprint across 1 IANA zone.
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.
JST country anchor Japan: Japan is an island country in East Asia. Located in the Pacific Ocean off the northeast coast of the Asian mainland, it is bordered to the west by the Sea of Japan and extends from the Sea of Okhotsk in the north to the East China Sea in the south. The Japanese archipelago consists of four major islands alongside 14,121 smaller islands. Japan is divided into 47 administrative prefectures and eight traditional regions, and around 75% of its terrain is mountainous and heavily forested, concentrating its agriculture and highly urbanized population along its eastern coastal plains. With a population of almost 123 million as of 2026, it is the world's 11th most populous country. Tokyo is the country's capital and largest city. Source: Wikipedia.
JST is Japan civil time, centered on Tokyo, Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, and the rest of the Japanese domestic timetable. The useful context is Japan's no-DST posture, yen-denominated business cycles, Tokyo Stock Exchange timing, rail and aviation punctuality, anime/game/media release schedules, and holiday clusters such as Golden Week and year-end closures.
A JST conversion is often searched by teams coordinating with Japan specifically, not merely UTC+9. Product launches, live streams, travel arrivals, and support handoffs should account for Japanese business etiquette, local public holidays, and the difference between Japan's stable clock and regions where daylight saving changes the counterpart offset.
PST/JST uses America/Los_Angeles -> Asia/Tokyo, offset delta +17h, overlap 1h, route /convert/pst/jst/, and live abbreviation readings PST/GMT+9.
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.
JST coverage is led by Tokyo, Japan, Yokohama, Japan, Osaka, Japan, and Nagoya, Japan, 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 JST ranges from PST 9:00 AM (which lands at JST 2:00 AM) through PST 9:00 PM (JST 2:00 PM). Most of those slots fall on a different calendar day on the JST side, which is why this direction always needs explicit dates in invites and ticket comments — the time alone is not enough.
