Tokyo working hours seen from New York

Japan is 14 hours ahead of New York in winter and 13 hours ahead in summer. A 9:00 AM start in Tokyo is 7:00 PM the previous evening in New York in January and 8:00 PM in July. Enter a Japan time or press Use now to see the Eastern time.

Japan does not use daylight saving, so JST is always UTC+9. The change comes from New York, which moves its clocks in March and November. A fixed Tokyo time shifts by one hour on the Eastern clock twice a year, which matters for a regular meeting.

For a Tokyo team working with New York, the shared window is small. Tokyo 9:00 PM to 10:00 PM is 7:00 AM to 8:00 AM Eastern in January. A Tokyo evening call is a New York morning call, and Japan's late evening is the usual meeting slot. The hour-by-hour table shows a 9:00 to 17:00 Tokyo day on the Eastern clock, and it lands between 7:00 PM the night before and 3:00 AM.

Any Tokyo time earlier than 1:00 PM falls on the previous evening in New York, and the result says so. 6:00 PM in Tokyo is 4:00 AM the same Eastern day in January. Press swap to go from Eastern to Japan time.
