EST to JST Converter (Eastern Time to Japan Time)

Mid-January 2026: JST is 14 hours ahead of EST. Mid-July 2026: JST is 13 hours ahead of EDT.

Japan Standard Time (UTC+9) is the clock of Tokyo, Osaka, Kyoto, Nagoya, Sapporo and the whole country. Japan does not use daylight saving time, so New York, Boston and Washington are 14 hours behind Tokyo in winter and 13 hours behind when the United States moves to EDT.

People look this up for business with Japanese suppliers and subsidiaries, for flights to Narita and Haneda, for live events in Japan and for the opening of the Tokyo market. The date in Tokyo is nearly always one day later than the date in New York.

How to use this tool

1. Pick a date and time in EST. The date matters when daylight saving time is in force.
2. Read the matching time in JST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

JST time = EST time − (EST UTC offset) + (JST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM EST on March 2, 2026 = 11:00 PM JST

6:30 PM EDT on August 3, 2026 = 7:30 AM JST (next day)

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

Tokyo market hours on an Eastern clock

The Tokyo Stock Exchange trades from 9:00 a.m. to 11:30 a.m. and again from 12:30 p.m. to 3:30 p.m. Japan time. In New York that is 7:00 p.m. to 9:30 p.m. and 10:30 p.m. to 1:30 a.m. in winter, one hour later while the United States is on daylight saving time.

The result is that Japanese morning news arrives in the American evening. Analysts in New York who follow Japanese companies treat the Tokyo session as the "after-hours" part of their own day.

Working with a team in Japan

A 9 a.m. call in New York is already 11 p.m. in Tokyo during standard time, which is why Japanese managers often join early or late calls from home. The better arrangement is to hold meetings in the New York evening, when the Tokyo team arrives at the office the next morning.

Japanese business practice relies on punctual start times and sent agendas, so give the Tokyo date in your invitation and include the time in JST.
