When are both sides at work?Each column is one hour of the day in the first city; the second row shows the same moment in the other city. Gold means office hours (09:00–18:00), dusk means awake but off work, night means asleep (23:00–07:00). Columns where both rows are gold are good meeting times.
No overlap in standard working hours. Closest workable window: 09:00–11:00 in Singapore, which is 21:00–23:00 in Saint John’s.
