Convert ET to JST

Eastern Time (ET) to Japan Standard Time (JST)

Finance professionals, automotive industry teams (Detroit-Tokyo corridor), and tech companies with Japanese partners search this frequently. The 14-hour gap means New York's morning is Tokyo's late night, and vice versa — making synchronous collaboration especially difficult.

When it's 12:00 PM in New York, it's 1:00 AM in Tokyo (next day)

On Jan 1 – Mar 7, 2026; Nov 1, 2026 – Mar 13, 2027; Nov 7 – Dec 31, 2027: 2:00 AM in Tokyo (next day).

Scheduling Tips

Use 5:00-7:00 PM EST / 7:00-9:00 AM JST (next day) as your primary meeting window. Japan is fresh; the US is wrapping up but still engaged.
For urgent issues, 7:00-8:00 AM EST / 9:00-10:00 PM JST works, but keep meetings short — it is late evening in Tokyo.
Establish a clear async handoff rhythm: Japan works on tasks during their day, US picks up and hands back by end-of-day EST. The 14-hour gap becomes an advantage for follow-the-sun workflows.

Frequently Asked Questions

What is the time difference between EST and JST?

EST (Eastern Standard Time, UTC-5) is 14 hours behind JST (Japan Standard Time, UTC+9). When it is 9:00 AM in New York, it is 11:00 PM the same day in Tokyo. During EDT (UTC-4), the gap narrows to 13 hours.

Does JST change for daylight saving time?

No. Japan does not observe daylight saving time. JST remains UTC+9 year-round. The offset between Eastern time and JST changes only when the US switches between EST and EDT.

What is 9 AM EST in JST?

9:00 AM EST is 11:00 PM JST the same day. During EDT, 9:00 AM EDT is 10:00 PM JST. The US East Coast morning is late night in Tokyo.

What is 9 AM JST in EST?

9:00 AM JST is 7:00 PM EST the previous day. During EDT, 9:00 AM JST is 8:00 PM EDT the previous day. The Tokyo workday starts while New York is in the previous evening.

What is 5 PM EST in JST?

5:00 PM EST is 7:00 AM JST the next day. During EDT, 5:00 PM EDT is 6:00 AM JST. End of the US workday coincides with the very start of the Japanese business morning.

What is the best meeting time for EST and JST?

The most practical window is 7:00-9:00 AM EST / 9:00-11:00 PM JST, though this is late for Tokyo. Alternatively, 5:00-7:00 PM EST / 7:00-9:00 AM JST (next day) catches the Japanese morning while the US wraps up.

When does the EST-JST offset change?

Since Japan has no DST, the offset shifts only with US clock changes. In March (second Sunday), the gap goes from 14 to 13 hours when the US moves to EDT. In November (first Sunday), it returns to 14 hours when the US reverts to EST.

What is noon EST in JST?

12:00 PM (noon) EST is 2:00 AM JST the next day. During EDT, noon is 1:00 AM JST. US midday is the dead of night in Japan.
