Best overlap: 8:00 AM to 11:00 AM in Amsterdam is 3:00 PM to 6:00 PM in Tokyo.
Your shared working hours run 8:00 AM to 11:00 AM in Amsterdam (3:00 PM to 6:00 PM in Tokyo). You get roughly 3 hours of shared time, so aim for the middle of that window to keep the call comfortable for both teams. Because only Amsterdam changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Amsterdam enters or leaves daylight saving.

An 8 AM Pacific launch is 5 PM in London and 1 AM in Sydney. Your blog post, your engineering on-call, your support team, and your Twitter schedule are all picking different hours. Here is how to plan a launch that does not embarrass you in any time zone. -
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. -
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. -
