What is the time difference between Tokyo and Washington DC?

Tokyo (JST, UTC+9) is 13 hours ahead of Washington DC when DC is on EST (UTC-5, roughly early November to mid-March), and 14 hours ahead when DC observes EDT (UTC-4, roughly mid-March to early November). Because the offset exceeds 12 hours, Tokyo is usually one calendar day ahead of Washington DC.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952 and has not used it since. Tokyo stays on JST (UTC+9) year-round.

Does Washington DC observe Daylight Saving Time?

Yes. Washington DC (and the rest of the US East Coast) switches to EDT (UTC-4) on the second Sunday of March and returns to EST (UTC-5) on the first Sunday of November. This means the Tokyo-Washington DC offset changes between 13 and 14 hours depending on the time of year.

What are the best meeting times for Tokyo and Washington DC?

Tokyo business hours 09:00-18:00 JST correspond to 20:00-05:00 EST (21:00-06:00 EDT) the previous day in Washington DC. There is virtually no natural business-hour overlap. The closest window is 08:00-09:00 Washington DC time, when Tokyo is already at 21:00-22:00 JST — one side will need to work outside normal hours.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser, which includes all historical and future DST transitions for America/New_York. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What does EST and EDT stand for?

EST stands for Eastern Standard Time (UTC-5), used by Washington DC in winter. EDT stands for Eastern Daylight Time (UTC-4), used during daylight saving months from the second Sunday of March to the first Sunday of November.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to America/New_York time, which covers Washington DC (EST UTC-5 in winter, EDT UTC-4 in summer).
The UTC offsets of both cities are compared: 13 hours difference in winter (EST), 14 hours in summer (EDT).
Both clocks and the offset refresh every second in real time.
The converter lets you enter any Tokyo time and instantly see the equivalent Washington DC time.
