World Hour

The Real Scheduling Guides

Not just the time difference — the real overlap window, who absorbs the cost, and when your standing invites quietly break.

Europe ↔ North America
New York ↔ London Only ~3 real overlap hours — all at London's end of day. 5 hr gap Frankfurt ↔ New York The financial market axis. Two market opens, 6 hours apart, one narrow window. 6 hr gap Stockholm ↔ New York Overlap lives entirely in Sweden's late afternoon — 3 hours that disappear fast. 6 hr gap Gothenburg ↔ Detroit The Volvo–Michigan corridor. 3 hours of overlap, all at Sweden's end of day. 6 hr gap Amsterdam ↔ New York ASML, Shell, Philips and the Dutch–US corridor. 3 hours of overlap, all in Amsterdam's late afternoon. 6 hr gap
Amsterdam ↔ New York Dutch multinationals with US operations — same window as Frankfurt, different stakes. Coming soon
San Francisco ↔ London The startup and VC corridor — 8 hours apart, almost no clean overlap. Coming soon
Europe ↔ Middle East & Asia
London ↔ Dubai Dubai never moves. Only London's clocks shift — and that changes everything twice a year. 3–4 hr gap Dubai ↔ New York 8–9 hours apart. New York mornings and Dubai late afternoons are the only viable window. 8–9 hr gap London ↔ Singapore Near-zero standard overlap — 7 or 8 hours apart depending on UK DST. 7–8 hr gap Munich ↔ Seoul German automotive meets Korean manufacturing — 1–2 hours of overlap, all at Seoul's end of day. 7–8 hr gap Stuttgart ↔ Beijing Daimler and China JV coordination — 2–3 hours of overlap in Germany's morning and China's late afternoon. 6–7 hr gap London ↔ Mumbai The +5:30 offset — never round India to "5 hours ahead." 3–4 hours of clean overlap in London mornings. 4.5–5.5 hr gap
US Domestic
New York ↔ Los Angeles 3 hours, always. Still costs someone their morning or evening. 3 hr gap
Americas
São Paulo ↔ New York Only 1–2 hours apart — but the small gap is exactly why standing invites quietly break every March and November. 1–2 hr gap
APAC ↔ Europe & Americas
Stockholm ↔ Tokyo One real overlap hour — Japan never moves, Sweden does twice a year. 7–8 hr gap Sydney ↔ London Opposite hemispheres — the gap changes direction twice a year, passing through three different phases. 9–11 hr gap
Tokyo ↔ New York 13–14 hours apart. Every meeting lands on a different calendar day for someone. Coming soon
Singapore ↔ New York 12–13 hour gap — the corridor where no time is convenient for anyone. Coming soon
