Daylight saving notes
In the United States and Canada, daylight saving time runs from the second Sunday in March to the first Sunday in November. That affects Eastern Daylight Time (EDT).

Below are the answers people search for most when converting Eastern Daylight Time (EDT) to Japan Standard Time (JST).
How does the EDT to JST converter work?
It takes three quick steps:
- Click the EDT field on the left and pick the time you want to convert.
- The matching JST time updates on the right automatically — there’s no button to press.
- Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.
What is the time difference between EDT and JST?
JST is 13 hours ahead of EDT. In everyday terms, once you know the time on one side you just add 13 hours to get the other — so a call between New York and Tokyo is always 13 hours apart.
What's the current time in JST?
Right now the time in Japan Standard Time (JST) is Tuesday, June 30, 2026 · 2:53:55 AM. It ticks every second, so you’re always looking at the live JST clock.
And what time is it in EDT?
And in Eastern Daylight Time (EDT), it’s currently Monday, June 29, 2026 · 1:53:55 PM. Compare the two and the 13 hours gap is easy to see.
When is a good time to schedule a EDT to JST meeting?
For example, a 9:00 AM EDT meeting takes place at 10:00 PM JST. 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 EDT–JST difference?
The labels EDT and JST 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 EDT to JST conversion?
We don’t guess. EDT and JST 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 ahead of EDT is JST?
JST is 13 hours ahead of EDT — a fixed 13 hours difference, since both are fixed-offset labels.
What time is it in JST when it's 12:00 PM EDT?
When it's 12:00 PM (noon) EDT, it's 1:00 AM JST the next day.
Do EDT or JST use daylight saving time?
Eastern Daylight Time (EDT) observes daylight saving, alternating with EST; Japan Standard Time (JST) is a fixed offset with no daylight saving.
Why might the real-world EDT–JST difference change during the year?
The labels EDT and JST 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 EST to JST. Always check which label a region is currently using before you schedule.
