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. -
San Diego is 16 hours behind Seoul
Best overlap: 8:00 AM to 10:00 AM in Seoul is 4:00 PM to 6:00 PM in San Diego.
Aim for 8:00 AM to 10:00 AM Seoul time — that's 4:00 PM to 6:00 PM over in San Diego. With about 2 hours of common time, this pairing rewards planning — 8:00 AM in Seoul / 4:00 PM in San Diego is the slot to defend. One thing to flag — this overlap crosses the date line, so San Diego is on the previous day relative to Seoul. These times hold for most of the year, but San Diego's daylight saving (which Seoul doesn't use) shifts them by an hour twice annually.
