Tokyo never shifts its clock, so the 16-to-17-hour gap changes only twice a year, on US daylight-saving dates." --- [Home](https://watchtimeonline.com/) / [Local Zone Time](https://watchtimeonline.com/tools/world-clock.html) / Los Angeles vs Tokyo # Los Angeles vs Tokyo Time Difference A live, side-by-side look at the gap between Los Angeles and Tokyo — 17 hours apart in winter, 16 in summer, since only Los Angeles shifts its clock for daylight saving. Los Angeles --:--:-- America/Los\_Angeles – gap Tokyo --:--:-- Asia/Tokyo Calculating the live gap… Los Angeles zone Pacific Time · America/Los\_Angeles Tokyo zone Japan Standard Time · Asia/Tokyo (fixed) Typical gap 16–17 hours · Tokyo ahead Gap changes on Calculating… ## Almost exactly opposite sides of the clock Los Angeles and Tokyo sit close to 16–17 hours apart, which in daily life plays out as being almost exactly on opposite schedules — when one city is deep in its workday, the other is usually asleep. Unlike a pair where both sides observe daylight saving on different calendars, this one is simpler than it looks: Tokyo has held a fixed UTC+9 since 1886 (aside from a brief 1948–1951 DST experiment) and hasn't shifted since, so every bit of movement in this gap comes from one side only — Los Angeles. That makes the LA-Tokyo relationship easy to reason about once you know the rule: the gap is 17 hours whenever Los Angeles is on Pacific Standard Time (roughly November to March) and 16 hours whenever it's on Pacific Daylight Time (roughly March to November). There's no mismatched-calendar complexity to track, as there would be comparing two DST-observing cities — just two fixed values and two clean transition dates, both set entirely by the US calendar. **Trivia:** Because the gap is so close to a full day, Tokyo is often experiencing "tomorrow" relative to Los Angeles for a large part of the LA day — a useful mental model when scheduling anything date-sensitive between the two. ## Why the gap changes twice a year Since Tokyo never moves its own clock, the only two moments the LA-Tokyo gap ever changes are the two dates Los Angeles's clock changes — both set by US federal law, not by any coordination with Japan. LA DST starts (springs forward) – LA DST ends (falls back) – Both dates above are calculated live from the actual US clock-change rule for this year, so they stay correct automatically without anyone updating this page. ## Best time to call, hour by hour The table below runs through a full Los Angeles day and shows the matching Tokyo time for each hour, with the rows where both cities fall inside a typical 9:00–17:00 workday highlighted — there usually aren't many. | Los Angeles time | Tokyo time | Both in business hours? | | --- | --- | --- | | Calculating… | | | Where the table shows no overlap, the practical workaround most teams use is an early-morning call on one side meeting a late-afternoon or evening slot on the other. **How we calculate this page:** both live clocks, the current gap, the DST transition date, and the hour-by-hour overlap table are all computed directly from the IANA *America/Los\_Angeles* and *Asia/Tokyo* time zone data via your browser on every page load. ## Frequently asked questions ### What is the time difference between Los Angeles and Tokyo right now? Seventeen hours during Pacific Standard Time (roughly November to March) and sixteen hours during Pacific Daylight Time (roughly March to November). Tokyo never shifts its own clock, so the entire change comes from Los Angeles. ### Why does the Los Angeles-Tokyo gap change if Tokyo never shifts its clock? Because Los Angeles does. The United States moves clocks forward on the second Sunday of March and back on the first Sunday of November. Since Tokyo holds a fixed UTC+9 year-round, those two US transition dates are the only moments the LA-Tokyo gap ever changes. ### What is the best time to schedule a call between Los Angeles and Tokyo? There's very little natural overlap. The most workable window is a Los Angeles early morning (around 4:00–6:00 a.m.) meeting a Tokyo late afternoon/evening the same calendar day, or a Tokyo early morning meeting an LA late afternoon the day before. ### Is Tokyo ahead of or behind Los Angeles? Tokyo is always ahead of Los Angeles — by 16 to 17 hours, which in practice usually means Tokyo is experiencing tomorrow while Los Angeles is still on today. ### How do I convert Los Angeles time to Tokyo time? Add 16 hours during Pacific Daylight Time or 17 hours during Pacific Standard Time (and adjust the calendar date forward).
