How to read the chart
The left column is the local time in New York, the other columns show the same moment in Tokyo in January and in July. “+1 day” means it is already the next calendar day in Tokyo, “−1 day” — still the previous one. Rows outside 9:00–18:00 are dimmed. The converter above works the other way too: press “Swap” to enter a time in Tokyo.
