Meeting window
Working days of 9 AM to 5 PM do not overlap. The least disruptive slot is around 4:30 PM EDT, which is 5:30 AM (next day) JST while EDT and JST apply.

Eastern Time changes its clocks twice a year; Japan Standard Time does not.

The same conversion works for every city on these clocks, such as New York to Japan, New York to Tokyo and Toronto to Japan.
