About JST and EST
Japan Standard Time (JST) is used across Japan, including Tokyo and Osaka. Japan does not observe daylight saving time.
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.
Time difference between JST and EST
EST is 14 hours behind JST in winter (January) and 13 hours behind JST 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.
