Best time to call Tokyo from New York (and vice versa)

With 13 hours between them there is no hour at which New York and Tokyo are both inside a 9:00–17:00 working day. Teams split across these two cities usually alternate the sacrifice: one week the meeting lands early (7:00–8:00) in New York and late (18:00–19:00) in the other city, the next week the other way round. The Timezone Matcher grid shades exactly those compromise hours.

The two time zones

New York — America/New_York

New York keeps Eastern Time (ET): UTC−5 in winter (EST) and UTC−4 in summer (EDT), the reference zone for US finance, media and the whole East Coast from Boston to Miami.

Tokyo — Asia/Tokyo

Tokyo keeps Japan Standard Time (JST), a fixed UTC+9 with no daylight saving. Japan and South Korea share the offset, so Tokyo and Seoul are always on the same clock.
