US to Asia Meeting Planner
The US ↔ Asia corridor has the toughest overlap on the planet. Use these tools to find the least-bad windows for live calls and to plan async handoffs.
Standard 9-to-5 hours rarely overlap between US and East Asian offices. The most-used windows are 5–7 PM Pacific = 9–11 AM next-day Tokyo / Seoul (an hour later in each case from November to March, when the US is back on standard time), or 6–8 AM Pacific = late evening Tokyo. India sits roughly in the middle: 8–10 PM Eastern is the start of the next business day in Mumbai and Bangalore.
India, China, Japan, Korea, and Singapore do not observe daylight saving. The US does, so the offset between these cities and any US city shifts by one hour twice a year. The Clockjumper converter handles this automatically.
The US–Asia corridor is one of the lowest-overlap pairs studied in our global work-corridor overlap research — see the data for exact overlap hours per pair.
