Planning a call with colleagues overseas? Here are the best windows where standard business hours (9 AM – 5 PM) overlap between popular city pairs.
Best overlap: 9:00 AM – 12:00 PM EST (2:00 PM – 5:00 PM GMT). A 3-hour window during afternoon London time and morning New York time. Most transatlantic meetings are scheduled in this slot.
Best overlap: 9:00 AM – 11:00 AM GMT (5:00 PM – 7:00 PM SGT). A narrow 2-hour window. For longer meetings, one side typically adjusts to early morning or late evening hours.
Minimal overlap during standard hours. 7:00 AM – 8:00 AM EST = 9:00 PM – 10:00 PM JST. Most teams use async communication or alternate early/late meetings between the two offices.
Best overlap: 8:00 AM – 9:00 AM PST (5:00 PM – 6:00 PM CET). Only a 1-hour window, making real-time collaboration challenging. Many US-EU distributed teams rely on morning standups Pacific time.
Best overlap: 5:00 PM – 9:00 PM GST (9:00 AM – 1:00 PM EST). A generous 4-hour window makes Dubai a surprisingly convenient hub for transatlantic and Asian business coordination.
Best overlap: 7:00 AM – 8:00 AM AEST (9:00 PM – 10:00 PM GMT previous day). Extremely limited. Teams typically rotate meeting times or use recorded video updates for async handoffs.
