About these time zones
EST. Eastern Time is EST (UTC-5) in winter and EDT (UTC-4) from the second Sunday in March to the first Sunday in November. It covers New York, Toronto, Miami and most of the US East Coast.
JST. Japan Standard Time is UTC+9 all year. Japan does not observe daylight saving, so any change in the gap comes from the other zone.
Overlap. There is no hour that falls inside a 9 to 5 working day in both zones, so one side has to meet early or late. Early morning in one zone and early evening in the other is usually the least painful option.
