Convert JST to EDT Time Zone
A quick guide to JST → EDT: the time gap, the live clocks, scheduling tips, and how we keep it accurate.

JST vs EDT: what's the time gap?
EDT is 13 hours behind JST. In everyday terms, once you know the time on one side you just subtract 13 hours to get the other — so a call between Tokyo and New York is always 13 hours apart.
What's the current time in EDT?
Right now the time in Eastern Daylight Time (EDT) is Monday, June 29, 2026 · 1:54:04 PM. It ticks every second, so you’re always looking at the live EDT clock.
And what time is it in JST?
And in Japan Standard Time (JST), it’s currently Tuesday, June 30, 2026 · 2:54:04 AM. Compare the two and the 13 hours gap is easy to see.
What's the best time for a JST–EDT call?
For example, a 9:00 AM JST meeting takes place at 8:00 PM EDT (−1 day). The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the JST–EDT difference?
The labels JST and EDT are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this JST to EDT conversion?
We don’t guess. JST and EDT times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours behind JST is EDT?
EDT is 13 hours behind JST — a fixed 13 hours difference, since both are fixed-offset labels.
What time is it in EDT when it's 12:00 PM JST?
When it's 12:00 PM (noon) JST, it's 11:00 PM EDT the previous day.
Do JST or EDT use daylight saving time?
Japan Standard Time (JST) is a fixed offset with no daylight saving; Eastern Daylight Time (EDT) observes daylight saving, alternating with EST.
Why might the real-world JST–EDT difference change during the year?
The labels JST and EDT are fixed offsets, so this converter is always exact. But Eastern Daylight Time's region switches between standard and summer time, so for part of the year you may actually want JST to EST. Always check which label a region is currently using before you schedule.
