Meeting planner: the best time to meet across time zones

The hour that works in every city.

Japan & San Francisco has its own page, with the year ahead and calling hours

A working day · Japan time

9:30–10:30 am Japan

4:30–5:30 pm, day before in San Francisco

No hour fits everyone’s hours. At the closest fit, Japan starts 1½ hours early, and San Francisco stays 1½ hours late.

Works Tue–Fri, when everyone is on a working day.

Meeting every week?
Taking turns is fairer: rotate between 8 am and 11 am Japan time, a different one each week.

How it works

What counts as a good time?

The whole meeting has to sit inside everyone’s hours on their own clock: a working day, 9 am to 6 pm, unless you choose other hours.

What if there’s no hour that suits everyone?

Then Meridian picks the closest fit and says who has to start early or stay late. For a meeting every week, it says whether taking turns would be fairer.

Does it know about clock changes and weekends?

Yes. Every answer is for today’s clocks, and when weekends differ, as between New York and Tel Aviv, it says which days work.
