•The Time Gap Between New York and Tokyo
New York runs at UTC-5 in January and UTC-4 in July, shifting its clocks for Daylight Saving Time.
Tokyo runs at a fixed UTC+9 year-round, with no Daylight Saving Time.
Because only New York observes Daylight Saving Time, the gap changes every time its clocks do: it runs 13 hours for roughly 8 months of the year and 14 hours for the other 4. Any recurring meeting between these two needs to be checked twice a year, not set once and forgotten.
Realistic Overlap for a Standard 9-to-5
Assuming a standard 9am–5pm workday on both ends, New York and Tokyo share no true overlap. There's no window where both teams are in a standard workday at the same time, so this pairing needs to run async by default, with any live call landing outside someone's normal hours.
- January: the one-hour slot that splits the inconvenience most evenly is 5:30pm in New York = 7:30am in Tokyo (next day).
- July: the one-hour slot that splits the inconvenience most evenly is 6:00pm in New York = 7:00am in Tokyo (next day).
2026 Clock Changes for New York and Tokyo
These are the dates in 2026 when the gap between the two cities changes. Around each one, check that recurring invites still land where you expect — calendar apps anchor a meeting to its organizer's time zone, so it's the other side's local time that moves.
- Jan 1 — Tokyo is 14 hours ahead of New York.
- Mar 8 — New York springs forward to UTC-4, so Tokyo is now 13 hours ahead of New York.
- Nov 1 — New York falls back to UTC-5, so Tokyo is now 14 hours ahead of New York.

EST to JST: What the Abbreviations Mean
EST — Eastern Standard Time (EST, UTC-5) runs part of the year; the rest of the year the same clocks are on Eastern Daylight Time (EDT, UTC-4) instead. People casually say "EST" for both — the scrubber above already resolves whichever one is actually in effect for the date you pick.
JST — Japan Standard Time (JST) is fixed at UTC+9 year-round — it does not observe Daylight Saving Time.
Timezone abbreviations aren't globally unique — several regions reuse the same three or four letters for unrelated zones. The scrubber is anchored to IANA timezone data (America/New_York and Asia/Tokyo) rather than the abbreviation text, so there's no ambiguity in the actual conversion.
