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, 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.
