About EST and JST
US Eastern Time (EST/EDT) is used in New York, Washington DC, Boston, Atlanta, Miami and Toronto. Clocks shift to EDT (daylight time) from March to November.
Japan Standard Time (JST) is used across Japan, including Tokyo and Osaka. Japan does not observe daylight saving time.
Time difference between EST and JST
JST is 14 hours ahead of EST in winter (January) and 13 hours ahead of EST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
