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 5:00 PM in New York is 9:00 AM to 6:00 PM in São Paulo.
Aim for 8:00 AM to 5:00 PM New York time — that's 9:00 AM to 6:00 PM over in São Paulo. São Paulo is 1 hour ahead of New York, but the generous 9-hour window means both teams can meet well within their normal day. These times hold for most of the year, but New York's daylight saving (which São Paulo doesn't use) shifts them by an hour twice annually.

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. -
