Best Meeting Times Between US and Japan Teams (2026)
8 AM Tokyo is 4 PM in Los Angeles the day before. West Coast afternoon windows, the East Coast dead zone, and why the Philippines slot is an hour off. -
Best overlap: 5:30 PM to 6:30 PM in Tehran is 8:00 AM to 9:00 AM in Denver.
The hours that work for both Tehran and Denver are 5:30 PM to 6:30 PM (Tehran) and 8:00 AM to 9:00 AM (Denver). Denver is 9.5 hours behind Tehran, which leaves a narrow 1-hour window. Treat 5:30 PM in Tehran (8:00 AM in Denver) as the time and build around it. Note the seasonal wrinkle: when Denver is on daylight saving and Tehran isn't, the gap between them grows or shrinks by an hour.

London to New York is five hours apart, except for the five weeks a year when it isn't. Exact overlap windows for every US zone, the 2026 DST mismatch dates, and where to put the recurring sync. -
The Philippines sits 12 to 16 hours ahead of the US and never changes its clocks. Exact overlap windows for every US coast, the tomorrow problem, and a rotation rule that works for product and BPO teams. -
