Each Tokyo hour with the US Eastern time in both seasons. −1 marks a time that is on the previous day in New York.

Across the date line

With a gap this large, the calendar day nearly always differs. From midnight to 1:00 PM Tokyo time (2:00 PM in winter) it is still yesterday in New York. Only in the Tokyo afternoon and evening do the two cities share a date.

A handy rule: instead of subtracting 14, add 10 and step back one day. In US summer, add 11 and step back one day. The converter does both steps for you, including the day label.

Clock changes on the US side only

Japan has kept UTC+9 without daylight saving for decades; NICT generates the national time signal. The United States moves to EDT at 2:00 AM on the second Sunday of March and back to EST at 2:00 AM on the first Sunday of November, under rules overseen by the US Department of Transportation.

Picking a meeting slot

Do

  • Meet at 8:00–9:00 AM in Tokyo, which is 7:00–8:00 PM the previous evening in New York during EDT.
  • Write the weekday for both cities, for example Tue 8:00 AM JST / Mon 7:00 PM EDT.

Avoid

  • Booking a Monday morning in Tokyo from New York on Monday morning: that time has already passed in Japan.
  • Forgetting that the New York evening slot moves an hour later in November.

The same numbers apply to Seoul, and the live Toronto and Washington, DC clocks follow Eastern Time. For the US West Coast, see JST to PST.

JST to EST questions

How many hours is Japan ahead of New York?

Japan is 14 hours ahead of New York while the US is on EST, from early November to mid-March, and 13 hours ahead while it is on EDT.

What time is it in New York at 9:00 AM in Tokyo?

It is 7:00 PM the previous day on EST and 8:00 PM the previous day on EDT.

Do Tokyo clocks ever change for summer?

No. Japan Standard Time is UTC+9 all year, so every change in the gap comes from the US side.

Is there a quick way to convert JST to EST?

Add 10 hours (or 11 in US summer) to the Tokyo time and go back one calendar day. 9:00 AM Tuesday in Tokyo becomes 7:00 PM Monday in New York in winter.

Which time zone is Seoul in compared with Tokyo?

Seoul uses Korea Standard Time, also UTC+9, so it reads the same as Tokyo. Use the KST to EST page for Korea.
