Meeting planner
London, New York, and Tokyo have no hour that is 09:00-17:00 in all three cities on 09 Nov 2026.
The grid is calculated in the browser. Add or remove cities. Hours in the 09:00-17:00 window are marked.
How the grid is read
Working day
09:00 to 17:00, local
A cell is marked when that UTC hour is inside the working day in every selected city. Tokyo morning is still yesterday evening in New York. The table makes that visible.
Clock changes
DST shifts the overlap
When one city springs forward and another has not, the overlap band moves. Country DST pages list the local change.
