Summary
Tokyo runs on JST (Japan Standard Time, UTC+9) year-round with no Daylight Saving Time. Washington DC observes EST (Eastern Standard Time, UTC-5) in winter and EDT (Eastern Daylight Time, UTC-4) in summer. Tokyo is 14 hours ahead when DC is on EST and 13 hours ahead when DC is on EDT (under the current US rules, from the second Sunday in March to the first Sunday in November). Because Tokyo is often a calendar day ahead, scheduling between Japan and the US East Coast requires careful attention to both date and time.
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: 14 hours difference in winter (EST), 13 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.
