Time Difference: New York and Tokyo
Tokyo is 14 hours ahead of New York in winter and 13 hours ahead in summer. 7:00 PM in New York is 9:00 AM the next day in Tokyo on EST and 8:00 AM the next day on EDT.
Half a Day Apart, With One Hour of Movement
New York is UTC-5 in winter and UTC-4 in summer, and Tokyo is UTC+9 all year, so the gap is 14 hours on EST and 13 hours on EDT. Tokyo is the fixed end of the pair.
Because it is more than half a day, Tokyo is usually on the next calendar day for a New York evening: 8:00 PM in New York is 10:00 AM the next day in Tokyo on EST and 9:00 AM the next day on EDT. Going the other way, Tokyo's 9:00 AM is 7:00 PM the previous day in New York on EST, the previous evening.
Do Any Working Hours Meet?
A 9-to-5 day on each side never meets, in either season. The practical window is a New York evening and a Tokyo morning: 7:00 to 9:00 PM in New York is 9:00 AM to 11:00 AM the next day in Tokyo on EST, and 8:00 AM to 10:00 AM the next day on EDT.

| 6:00 PM | 8:00 AM (next day) | 7:00 AM (next day) |
Each row is an hour of the New York day. A check mark means both cities are inside a 9 AM to 5 PM working day at that moment.
- EST → JST: no shared working hours.
- EDT → JST: no shared working hours.
In the other direction, Tokyo's early evening is a New York morning.

* "next day" / "prev day" = the converted time falls on a different calendar date.
Two Dates a Year
Tokyo never changes its clocks, so the gap moves only when New York does:
- Second Sunday in March: New York moves to EDT and the gap narrows from 14 hours to 13.
- First Sunday in November: New York moves back to EST and the gap widens to 14 hours again.
A 7:00 PM Monday call in New York is 9:00 AM the next day in Tokyo, which is Tuesday morning. Quote both dates in the invite.
A Weekly 8 PM Call From New York
A New York team that calls Tokyo every week at 8:00 PM reaches 10:00 AM the next day on EST and 9:00 AM the next day on EDT, so the call lands in the Tokyo morning of the next day. A 6:00 PM start is 8:00 AM the next day on EST.
If Tokyo hosts at 9:00 AM, New York joins at 7:00 PM the previous day on EST and 8:00 PM the previous day on EDT, the previous evening. The series stays put on Tokyo's side while New York's time moves by an hour in March and November.
