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: 8:00 AM to 11:00 AM in New York is 3:30 PM to 6:30 PM in Tehran.
The overlap falls at 8:00 AM to 11:00 AM in New York, or 3:30 PM to 6:30 PM if you're in Tehran. Tehran is 7.5 hours ahead of New York. That leaves about 3 hours of common time — enough for a meeting or two, so use it deliberately. Watch the DST gap — when New York changes its clocks and Tehran stays the same, this window slides 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. -
Slack converts timestamps automatically and shows everyone's local time, but it can't fix a bare '3 PM' typed into a channel. The settings worth changing and the habits that do the rest. -
