Convert JST to EST
EST = JST −14 h
EST is 14 hours behind JST. JST is always UTC+9 and EST is always UTC−5, so this gap is the same on every date.

New York is on EST (UTC−5) right now.
- Next clock change: March 14, 2027. New York moves to EDT (UTC−4), so New York is then 13 hours behind Japan.
- Next clock change: November 7, 2027. New York moves to EST (UTC−5), so New York is then 14 hours behind Japan.
JST to EST for every hour
Each EST column holds for part of the year (dates in the header for 2027). The first uses the fixed offsets (JST UTC+9, EST UTC−5); the others give local clock time when daylight saving time changes the gap. Until 2:00 PM JST, EST is still on the previous calendar day.

Bold rows fall inside office hours (9:00 to 17:00) on both sides. The dot marks the current JST hour.

Does the difference change during the year?
As written, no: JST is always UTC+9 and EST is always UTC−5, so the gap is 14 hours on every date. But New York uses EST only in winter, and people often keep writing “EST” when they mean the local time. Between the local clocks of Japan and New York, the gap is 14 hours or 13 hours:
| From | What changes | Japan | New York | EST vs JST |
|---|---|---|---|---|
| January 1 | Start of the year | JST (UTC+9) | EST (UTC−5) | −14 h |
| March 8 | New York moves to EDT (UTC−4) | JST (UTC+9) | EDT (UTC−4) | −13 h |
| November 1 | New York moves to EST (UTC−5) | JST (UTC+9) | EST (UTC−5) | −14 h |
| From | What changes | Japan | New York | EST vs JST |

Converting JST to EST by hand
With the fixed offsets, take away 14 hours: 3:30 PM JST is 1:30 AM EST. In your head it is easier to swap AM and PM, then take away 2 hours: 3:30 PM, 3:30 AM, 1:30 AM.
With the −13 h gap (Mar 14 – Nov 7), take away 13 hours: 3:30 PM JST is 2:30 AM EST. In your head it is easier to swap AM and PM, then take away 1 hour: 3:30 PM, 3:30 AM, 2:30 AM.
Going back from EST to JST, do the opposite.
Where the JST and EST working days overlap
JST to EST (−14 h): Two 9:00–17:00 days do not overlap at all. To meet between 7:00 AM and 9:00 PM on both sides, start at 7:00 AM to 11:00 AM JST (5:00 PM to 9:00 PM EST), or 9:00 PM JST (7:00 AM EST).
−13 h (between Mar 14 and Nov 7, 2027): Two 9:00–17:00 days do not overlap at all. To meet between 7:00 AM and 9:00 PM on both sides, start at 7:00 AM to 10:00 AM JST (6:00 PM to 9:00 PM EST), or 8:00 PM to 9:00 PM JST (7:00 AM to 8:00 AM EST).
A meeting fixed in one city’s calendar moves by an hour for the other when the gap changes. Calendar apps handle this when the event is saved in a named zone (for example Asia/Tokyo) rather than as a fixed offset.
What JST and EST mean
Japan Standard Time
JST is UTC+9, Japan’s time all year. Japan has no daylight saving time, so only the other side of a JST conversion can move.
Eastern Standard Time
EST is UTC−5. The US East Coast and eastern Canada (New York, Washington, Miami, Toronto, Montreal) use it only in winter; from the second Sunday of March to the first Sunday of November they are on EDT, UTC−4. Jamaica, Panama and Cancún keep it all year, and since 2026 so does Manitoba (Winnipeg).
